[0073] Reference Figure 2 , Figure 2 This is a flow chart of the first embodiment of the method for constructing a steel truss floor deck structure of the present application. The method is used for a terminal device and comprises the following steps:

[0074] Step S11: constructing an initial finite element analysis model according to a preset construction target, wherein the initial finite element analysis model includes a main keel and a secondary keel.

[0075] It should be noted that the executor of the present application is a terminal device, which is equipped with a reinforced truss floor deck structure construction program. When the terminal device executes the reinforced truss floor deck structure construction program, the steps of the reinforced truss floor deck structure construction method of the present application are implemented.

[0076] Generally speaking, a preset construction target may refer to parameters set by the user based on needs for constructing an initial finite element analysis model. The parameters in the preset construction target may be parameters set for an actual steel truss floor deck structure. The initial finite element analysis model is constructed using the preset construction target. The initial finite element analysis model includes the main purlin, secondary purlin and steel truss floor deck (including the corrugated steel plate at the bottom and the support columns of the lower temporary support).

[0077] Furthermore, the step of constructing an initial finite element analysis model according to a preset construction target includes: constructing an initial finite element analysis model using ABAQUS according to the construction target.

[0078] When modeling the corrugated steel sheet, the complex shape of the closed corrugated steel sheet is ignored, the steel consumption of the protruding part is converted, and added to the corresponding structural members according to its corresponding size and position. In the initial finite element model, the bottom corrugated steel sheet is simulated by shell elements in a four-node reduced integration format. The thickness direction of the shell element adopts the Simpson integration method with 9 integration points, and the steel support adopts a three-dimensional solid element in an 8-node reduced integration format. The interaction between the corrugated steel sheet and the bottom temporary support adopts surface-to-surface contact. When defining the contact properties, the contact in the normal direction adopts "hard" contact, and the friction formula in the tangent direction is defined as "penalty", with a friction coefficient of 0.1. The force loading method is to apply a uniformly distributed load on the upper part of the corrugated steel sheet. Three-dimensional displacement constraints and three-dimensional rotation constraints are applied around the corrugated sheet and the end plate of the temporary support.

[0079] Reference Figure 3 , Figure 3 1 is a structural diagram of the initial finite element analysis model of this application, 11 is a steel truss floor deck, 12 is a secondary keel, 13 is a main keel, and the main keel is Figure 3 There are 4 in the middle.

[0080] Step S12: Reconstructing the main keel and the secondary keel according to preset setting rules and multiple primary and secondary keel connection methods to obtain multiple intermediate finite element analysis models, each of which includes a steel truss floor deck.

[0081] In the present application, various primary and secondary keel connection methods include direct connection, in which the primary keel is directly in contact with the secondary keel, and indirect connection, in which the primary keel is connected to the secondary keel via a supporting member.

[0082] Among them, direct connection, first lay out the steel along the length direction, the upper surface of the steel is in direct contact with the floor steel plate, and its ends are in direct contact with the web of the main beam of the structure. In order to ensure the stability of the ends of the steel, the ends are supported on the lower flange of the main beam with wooden squares. Then lay out the steel along the short side direction, which is in direct contact with the steel arranged along the length direction, and its ends are also in direct contact with the web of the main beam. In order to ensure stability, its ends need to be connected to the stiffening ribs of the main beam by bolts.

[0083] Indirect connection, the two are connected by a support member. The main body of the support member is solid round steel, with a rectangular steel pad welded on the upper part to support the upper secondary keel. The lower part that contacts the main bracket is welded with a hollow cylindrical sleeve corresponding to the position of the main keel. The lower part of the support member passes through the hollow cylindrical sleeve, and the support member is fixed to the main bracket with a clamp on the upper part of the hollow sleeve. The end of the main keel extends to the belly of the steel beam and is directly placed on the lower flange of the main beam without other reinforcement measures.

[0084] Reference Figure 4-5 , Figure 4This is a schematic diagram of the structure of the direct connection between the primary and secondary keels in this application. Figure 5 This is a schematic diagram of the indirect connection structure of the primary and secondary keels in this application. Figure 4 In the keel, the main keel and the secondary keel are directly connected, and the secondary keel is set between the main beams on both sides. Figure 5 In the , the main keel and the secondary keel are connected by a dowel bar (a supporting member). Figure 4 and Figure 5 In the structure, the primary and secondary purlins are arranged on one side of the lower surface of the steel truss floor deck.

[0085] Specifically, the step of reconstructing the main keel and the secondary keel according to preset setting rules and multiple primary and secondary keel connection methods to obtain multiple intermediate finite element analysis models includes: setting a secondary keel at a target position on the surface of one side of the steel truss floor deck, and setting multiple main keels on a side of the secondary keel away from the steel truss floor deck, and connecting the secondary keel with multiple main keels according to the multiple primary and secondary keel connection methods to obtain multiple first finite element analysis models, wherein the secondary keel extends along the length direction of the steel truss floor deck, and the main keel extends along the width direction of the steel truss floor deck. The plurality of main keels are extended, and the plurality of main keels are spaced from each other in the length direction according to the first preset spacing; the plurality of main keels in each first finite element analysis model are reconstructed using the second preset spacing, and the secondary keels are connected to the reconstructed plurality of main keels according to the plurality of primary and secondary keel connection methods to obtain a plurality of second finite element analysis models; a force transmission component is set between the main keel and the secondary keel in each second finite element analysis model to obtain a plurality of third finite element analysis models; the plurality of first finite element analysis models, the plurality of second finite element analysis models and the plurality of third finite element analysis models are merged to obtain a plurality of intermediate finite element analysis models. A first finite element analysis model is an intermediate finite element analysis model, a second finite element analysis model is an intermediate finite element analysis model, and a third wired original analysis model is an intermediate finite element analysis model.

At this time, the intermediate finite element analysis models include 16.

[0089] Furthermore, before the step of merging the first finite element analysis model group and the second finite element analysis model group to obtain a plurality of the intermediate finite element analysis models, the method further includes: adding a plurality of secondary keels to each fourth finite element analysis model, and adjusting the spacing of the secondary keels of each fourth finite element analysis model after adding the secondary keels by using the seventh preset spacing to obtain a plurality of ninth finite element analysis models; adjusting the spacing of the secondary keels of each fourth finite element analysis model after adding the secondary keels by using the eighth preset spacing to obtain a plurality of tenth finite element analysis models; adding a plurality of secondary keels to each sixth finite element analysis model, and adjusting the spacing of the secondary keels of each sixth finite element analysis model after adding the secondary keels by using the ninth preset spacing to obtain a plurality of eleventh finite element analysis models; and adjusting the spacing of the secondary keels of each sixth finite element analysis model after adding the secondary keels by using the tenth preset spacing. The spacing of each secondary keel of the sixth finite element analysis model after the secondary keel is adjusted to obtain multiple twelfth finite element analysis models; a force transmission component is set between the main keel and the secondary keel in each of the twelfth finite element analysis models to obtain multiple thirteenth finite element analysis models; multiple ninth finite element analysis models, multiple tenth finite element analysis models, multiple eleventh finite element analysis models, multiple twelfth finite element analysis models and multiple thirteenth finite element analysis models are merged to obtain a third finite element analysis model group; the first finite element analysis model group and the second finite element analysis model group are merged to obtain multiple intermediate finite element analysis models, including: merging the first finite element analysis model group, the second finite element analysis model group and the third finite element analysis model group to obtain multiple intermediate finite element analysis models.

[0090] Specifically, based on the parameters of the actual corrugated steel sheet mentioned above, multiple (3) secondary purlins are added to each fourth finite element analysis model, and the spacing of the secondary purlins of each fourth finite element analysis model after the secondary purlins are added is adjusted using the seventh preset spacing (1 meter), so as to obtain two ninth finite element analysis models; the spacing of the secondary purlins of each fourth finite element analysis model after the secondary purlins are added is adjusted using the eighth preset spacing (1.5 meters), so as to obtain two tenth finite element analysis models; multiple (3) secondary purlins are added to each sixth finite element analysis model, and the spacing of the secondary purlins of each sixth finite element analysis model after the secondary purlins are added is adjusted using the ninth preset spacing (1 meter), so as to obtain two eleventh finite element analysis models; the spacing of the secondary purlins of each sixth finite element analysis model after the secondary purlins are added is adjusted using the tenth preset spacing (1.5 meters), so as to obtain two twelfth finite element analysis models; a force transmission member is set between the main purlin and the secondary purlin in each of the twelfth finite element analysis models, so as to obtain two thirteenth finite element analysis models. At this time, the intermediate finite element analysis models include 26. It can be understood that an Nth finite element analysis model (N is any value from 1 to 12) is an intermediate finite element analysis model.

[0091] It can be understood that in the present application, three groups of adjustments are mainly performed. The first group is the first finite element analysis model group mentioned above, including 6 intermediate finite element analysis models, the second group is the second finite element analysis model group mentioned above, including 10 intermediate finite element analysis models, and the third group is the third finite element analysis model group mentioned above, including 10 intermediate finite element analysis models.

[0092] Step S13: applying a uniformly distributed load to the steel truss floor deck of each intermediate finite element analysis model, and determining the deflection value of the steel truss floor deck of each intermediate finite element analysis model;

[0093] Step S14: determining a selected intermediate finite element analysis model from the plurality of intermediate finite element analysis models based on the deflection value of each intermediate finite element analysis model;

[0094] Step S15: using the selected intermediate finite element analysis model, constructing an actual steel truss floor deck structure corresponding to the preset construction target.

[0095] Among them, before the step of applying a uniformly distributed load to the steel truss floor deck of each of the intermediate finite element analysis models, the method also includes: obtaining the first self-weight of the steel truss floor deck in the initial finite element analysis model, the second self-weight of the concrete corresponding to the initial finite element analysis model, and the construction live load corresponding to the initial finite element analysis model; using the first self-weight, the second self-weight and the construction live load to determine the uniformly distributed load.

[0096] The uniformly distributed load is a uniformly distributed load, and the uniformly distributed load applied to the steel truss floor deck of each intermediate finite element analysis model is the same; the deflection value at the maximum deformation of the steel truss floor deck of each intermediate finite element analysis model is the deflection value.

[0097] The larger the deflection value, the larger the deformation, and the smaller the deflection value, the smaller the deformation. At this time, it is necessary to select the intermediate finite element analysis model with the smallest deflection value, and use the intermediate finite element analysis model to construct the actual steel truss floor deck structure corresponding to the preset construction target.

[0098] The technical solution of the present application proposes a method for constructing a steel truss floor deck structure, by constructing an initial finite element analysis model according to a preset construction target, the initial finite element analysis model including a main keel and a secondary keel; reconstructing the main keel and the secondary keel according to preset setting rules and a variety of primary and secondary keel connection methods to obtain a plurality of intermediate finite element analysis models, each of the intermediate finite element analysis models including a steel truss floor deck; applying a uniformly distributed load to the steel truss floor deck of each intermediate finite element analysis model, and determining the deflection value of the steel truss floor deck of each intermediate finite element analysis model; based on the deflection value of each intermediate finite element analysis model, determining a selected intermediate finite element analysis model from the plurality of intermediate finite element analysis models; and using the selected intermediate finite element analysis model to construct an actual steel truss floor deck structure corresponding to the preset construction target.

[0099] At present, the same scheme is used to set the actual steel truss floor deck structure, which makes the form of the steel truss floor deck structure single, and it is difficult to achieve effective resistance to the load in the scenarios corresponding to different preset construction targets. However, by using the method of the present application, a selected intermediate finite element analysis model is determined from a plurality of intermediate finite element analysis models, and the actual steel truss floor deck structure corresponding to the preset construction target is constructed by using the intermediate finite element analysis model. The actual steel truss floor deck structure can better match the scenario corresponding to the preset construction target, so that the actual steel truss floor deck structure can achieve effective resistance to the load, thereby improving the load resistance effect of the actual steel truss floor deck structure.
