Embodiment 1

[0055] A corrugated steel composite wall structure system suitable for steel structure residences, characterized in that, the principle: design a new type of corrugated steel composite wall as a side-resistant component unit, by adopting the design idea of ​​​​separating the side-resistant and load-bearing components of the structural system, according to the building Functional requirements, arrange sufficient and appropriate cross-sectional shapes at appropriate locations Corrugated steel composite wall anti-side member (referred to as Anti-side member elements, Figure 4 ); the anti-side member units are connected by hinged steel beams in the horizontal direction, and the anti-side member units are connected by joints in the vertical direction, thus forming a new structural system. At the same time, the overall analysis of the new structural system is carried out, and the corrugated steel plate composite wall and hinged steel beams are designed according to the results...

Embodiment 2

[0072] Based on Embodiment 1, a set of design methods for realizing the structural system is further disclosed.

[0073] Such as Figure 10 As shown, the design method of the corrugated steel composite wall structure system includes the following steps in sequence:

[0074] S1 First, obtain the possible arrangement positions of corrugated steel plate composite walls and hinged steel beams according to the building layout drawings;

[0075] According to the specific building layout, select side-resistant member units with different cross-sections such as in-line, L-shaped, T-shaped, Z-shaped, and cross-shaped, which are suitable for actual needs. The walls are connected by hinged steel beams (6-1) .

[0076] When conditions permit, energy-dissipating combined limb walls (cylinders) (5) with greater lateral stiffness can be arranged in conjunction with stairwells, elevators, etc., and energy-dissipating connecting beams (6-2) can be used to connect. When an earthquake occur...

Embodiment 3

[0082] Based on the design operation method of Embodiment 2, this embodiment envisages the development of a set of application software for designing and outputting construction system cases.

[0083] For example and not limitation, the application software includes building databases, including prefabricated three types of splicing structure models, including prefabricated cross-sections with different straight, L-shaped, T-shaped, Z-shaped, and cross-shaped anti-side member unit modules; application software algorithms The process is:

[0084] Step 1. Input the electronic drawings of the building layout, and obtain the possible arrangement positions of corrugated steel plate composite walls and hinged steel beams in the plan space, and provide step 2 after screening;

[0085] Step 2. Model and analyze the structure

[0086]In the analysis model, the corrugated steel plate composite wall is analyzed as a square steel pipe-corrugated steel plate-concrete composite structure s...

Abstract

The invention provides a corrugated steel plate composite wall structure system and a design method thereof. The corrugated steel plate composite wall structure system is characterized in that a novel corrugated steel plate composite wall is designed as a lateral-resistant component unit, and by adopting the design thought that lateral resistance and load bearing of the structure system are separated, according to the building function requirement, different corrugated steel plate composite wall lateral-resistant components which are enough and appropriate in section shape are arranged at appropriate positions; and the lateral-resistant component units are transversely connected through hinged steel beams, the lateral-resistant component units are spliced and connected in a node mode in the vertical direction, and therefore the novel structure system is formed. The corrugated steel plate composite wall and the hinged steel beams are preliminarily arranged according to a building drawing; modeling analysis is conducted on the preliminary arrangement, mechanical parameters of each component design are obtained, and an arrangement scheme which cannot guarantee the structure safety is eliminated through checking calculation; the specific corrugated steel plate composite wall and the hinged steel beams are designed according to the mechanical parameters of the components, and the section specification of each specific component is determined; and connecting nodes are designed according to the section specification of each component.

Description

technical field [0001] The invention relates to the technical field of structural engineering. Background technique [0002] Steel structures have been widely used in developed countries such as the United States, Japan, and the United Kingdom because of their advantages such as light weight, high strength, good earthquake resistance, factory production, fast construction speed, and recyclable materials. It accounts for more than 40% of the total construction, while the proportion of steel structure buildings in my country is less than 5%. [0003] The prefabricated steel-concrete composite structure residence has the advantages of high degree of industrialization, good quality, short construction period, good seismic performance, and high comprehensive technical and economic indicators. It is one of the prefabricated building systems supported by the state. Existing multi-story prefabricated steel-concrete composite structures can generally be divided into steel-concrete co...
