Description

Technical Field

[0001] The invention belongs to the technical field of building engineering, and in particular relates to a sheet-column cluster multi-story building structure and a design method thereof. Background Art

[0002] As an exhibition building with display as its main function, the building height will not be particularly high, but there are high requirements for the fluidity of the building space, the simplicity of the appearance, and the lighting and ventilation. At present, an architectural concept style that uses thin column clusters is very popular. All column sections in the building adopt thin columns with smaller cross-sectional widths to achieve space and appearance requirements. However, the column sections of existing frame, shear wall, frame cylinder or frame shear wall structures are usually large, otherwise it is difficult to meet the requirements of stability or strength. In addition, the building column grid is usually an orthogonal standard column spacing, and a single column is arranged at the intersection of the grid. The form is relatively simple and lacks variety, which cannot meet the requirements of the architectural style. It can be seen that the structural forms recommended by the current design specifications, such as frame, shear wall, frame cylinder or frame shear wall, cannot achieve this architectural form.

[0040] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the claims attached to the present invention.

It should be understood by those skilled in the art that technical users or manufacturers may refer to the same component or part by different nouns or terms. This specification and subsequent claims do not use differences in names as a way to distinguish components or parts, but use differences in functions of components or parts as the criteria for distinction. "Including" and "comprising" mentioned throughout the specification and subsequent claims are open-ended terms and should be interpreted as "including but not limited to".

[0043] The multi-story building structure of the column cluster of the present invention includes at least three building corners, for example, three building corners, and the overall appearance is triangular, but the present invention is not limited thereto, and the building corners can be four, five, etc., which are all within the scope of the modified examples of the present invention.

[0044] like Figure 1 and Figure 2 As shown, in the illustrated embodiment, the multi-story building structure 10 of the sheet-column cluster includes four building corners, and the overall appearance of the structure is a rectangular body. The following is an explanation of this commonly used appearance structure. The multi-story building structure 10 of the sheet-column cluster includes a lateral force-resistant corner tube 100, a non-lateral displacement gravity sheet column 200, a floor 300, and a roof 400, wherein the lateral force-resistant corner tubes 100 are arranged one-to-one with the building corners, that is, there are four lateral force-resistant corner tubes, which are distributed at the four corners of the building as the main lateral force-resistant structure. The outer peripheral connection lines of the lateral force-resistant corner tubes 100 constitute a building space, that is, the outer peripheral connection lines of the four lateral force-resistant corner tubes 100 constitute a rectangular building space.

[0045] There are multiple non-lateral gravity sheet columns 200, which are arranged in the building space and extend vertically, and the floor 300 and the roof 400 are arranged horizontally and connected to the lateral force resistance angle tube 100. Among them, the non-lateral gravity sheet columns 200 extend through the floor 300 of each layer and the roof 400 connected to the top.

[0046] In this embodiment, the multi-story building structure 10 of the sheet-column cluster is three-story, having two floors 300 and a roof 400 on the top, and the non-laterally shifted gravity sheet column 200 passes through the two floors 300 and is connected to the roof 400 on the top. In other embodiments, for example, the multi-story building structure 10 of the sheet-column cluster is two-story, having one floor 300 and a roof 400 on the top, the non-laterally shifted gravity sheet column 200 passes through one floor 300 and is connected to the roof 400 on the top.

[0047] In the present invention, the cross-sectional width of the non-lateral displacement gravity sheet column 200 does not exceed 150 mm. The slender column cross section cannot form effective lateral stiffness, and all columns are designed as swing columns that only bear gravity loads, and do not bear horizontal loads such as wind and earthquakes. The primary task of structural design is to improve the vertical stability bearing capacity of a single column. To this end, the structural system is first designed as a non-lateral displacement system to reduce the calculated length of the column by multiples.

[0048] The lateral force resisting angle tube 100 is a steel concrete shear wall component, which is used to bear the lateral force resisting requirements of the main structure. The column section width of all non-lateral displacement gravity sheet columns 200 is too small to be designed as frame columns, and they are all designed as gravity columns that only bear gravity.

[0049] Specifically, concrete shear wall components are arranged at the elevator traffic cores at the four corners of the building to form four lateral force-resisting corner tubes 100 with large lateral stiffness, which become the main lateral force-resisting system. Steel hidden columns and steel frame hidden beams are set inside the concrete shear wall, and the design is based on the medium earthquake non-yielding performance target to ensure the seismic ductility performance of the lateral force-resisting system under medium and large earthquakes. The four lateral force-resisting corner tubes 100 of the steel and concrete composite structure provide sufficient lateral resistance for the overall structure and ensure that the slender columns become gravity columns without lateral displacement. Figure 5 , which shows a perspective view of an embodiment of the arrangement of the core tube steel frame 110 of the lateral force resisting corner tube.

[0050] The architectural column network formed by the non-lateral displacement gravity sheet columns 200 is based on the natural growth concept of free thin column clusters like a forest, and the positions of the columns have certain random characteristics. The non-lateral displacement gravity sheet columns 200 mainly appear in the form of groups and clusters, and all column cross-sections are unified into rectangular shapes, but all have the basic characteristics of being slender.

[0051] It should be noted that the structure only retains necessary load-bearing columns, and each column is arranged as a single column or double column as required. On the other hand, single columns are avoided as much as possible in the side span. The non-lateral displacement gravity sheet column 200 of the present invention has a cross-sectional width controlled at 150MM, a length controlled at no more than 900MM, and a slenderness ratio of 106.7, which is greater than the limit of 82.5 for frame columns. The material is made of high-strength Q345 steel and a box-type section with a large cross-sectional turning radius. For a large number of column clusters, some columns are defined as decorative sheet columns 500. Figure 3 As shown, the decorative sheet column 500 is arranged between adjacent floor slabs 300 or between adjacent floor slabs 300 and roof slabs 400. For example, the decorative sheet column 500 is mainly arranged on the first floor. Of course, the decorative sheet column 500 can also be arranged on the second floor, the third floor, etc.

[0052] In the present invention, a plurality of zero-lateral-shift gravity sheet columns 200 are arranged adjacent to or closely to each other, or a plurality of decorative sheet columns 500 are arranged adjacent to or closely to each other, or a plurality of zero-lateral-shift gravity sheet columns 100 and decorative sheet columns 500 are arranged adjacent to or closely to each other, forming a cluster.

[0053] In general, the above-mentioned non-lateral displacement gravity sheet column 200, as a structural column, needs to bear the vertical gravity. Although its position is random, it is designed to meet the load-bearing requirements. The decorative sheet column 500 does not bear the vertical force and is only used for architectural decoration. Its position is arbitrary and random. In terms of construction sequence, the non-lateral displacement gravity sheet column 200 is part of the main structure, and the decorative sheet column 500 is a decorative column and can be installed after the main structure is completed.

[0054] like Figure 1 and Figure 4 As shown, the column cluster multi-story building structure 10 of the present invention further includes a ventilation and lighting cavity 600 , which extends vertically and penetrates the floor 300 and the roof 400 .

[0055] The floor 300 and the roof 400 are provided with horizontal steel structure supports 30, which form an integral horizontal truss with the floor and roof steel beams 20, and further form an integral lateral force resisting system together with the steel concrete lateral force resisting corner tubes 100 at the four corners of the building.

[0056] In order to ensure the effective lateral support of all thin columns by the four lateral force-resistant corner tubes 100, the horizontal steel structure support needs to be systematically designed to ensure the smoothness and completeness of the horizontal force transmission path. The design fully considers the impact of the setting of the full-height ventilation and lighting cavity 600 on the force transmission path. The horizontal steel structure support is designed to be non-yielding in moderate earthquakes to ensure the integrity and force transmission reliability of the structure under moderate and large earthquakes.

[0057] Among them, the large-span floor slabs of the second and third-floor column-drawn exhibition halls are spanned by one-way steel beams with large bearing capacity, and the gravity columns on the two supporting sides of the large-span steel beams are arranged in a random position with a small column spacing (3M~5M).

[0058] All the non-lateral displacement gravity sheet columns 200 are designed as three-story high gravity columns, and do not bear horizontal loads. In addition, the non-lateral displacement gravity sheet columns 200 provide vertical support for the horizontal steel structure support of the floor 300 and the roof 400, and the horizontal steel structure support of the floor 300 and the roof 400 in turn provides horizontal support for the non-lateral displacement gravity sheet columns 200.

[0059] The present invention not only ensures the safety of the structure but also satisfies the requirements of economic rationality through a hybrid structural system composed of steel-concrete shear walls, steel supports, steel columns, steel beams and corrugated steel plate concrete composite floor slabs. The present invention realizes the architectural expression of a forest-like free cluster of thin columns growing naturally, which has unique aesthetic value and artistic effect, and meets the functional requirements of providing natural lighting and ventilation by setting up multiple full-height long strip cavities inside the building. The new structural form proposed by the present invention enriches the selection of structural systems and provides the possibility of creating more new architectural forms.

[0060] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
