Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, in particular to a hybrid lateral force resisting structural system of residential building. BACKGROUND

[0002] Traditional high-rise steel structure residential buildings generally adopt steel frame support structural system. Although this system can bear vertical and horizontal loads, it still has many significant defects. In terms of spatial layout and use, in order to meet the vertical bearing requirement, the steel frame support structural system needs to set more columns, resulting in dense column grid and large column section size, which often protrudes from the wall surface, seriously encroaches on the effective use area of the indoor space, and directly affects the flexibility of furniture arrangement and space division. Sometimes, the diagonal bracing set to ensure lateral stiffness will inevitably pass through the wall, greatly limiting the location and size of the door and window openings, and bringing inconvenience to the building facade design and indoor space planning.

[0003] Secondly, the lateral stiffness of the steel frame support system is still relatively insufficient. Under the action of wind load or earthquake, the inter-story displacement of the structure is large, which easily leads to cracking or even falling of non-structural components (such as infilled walls, decorative plaster layers, etc.), affecting the normal use and safety of the building.

[0004] The floor system of the steel frame support structural system is mostly cast-in-place concrete with steel bar truss floor slab, which produces a large amount of wet work, has a long construction period, and has great difficulty in quality control; and such floor slab has a small applicable span to realize formwork-free and bracing-free; for the beamless large space area, the thickness of the slab increases and a large amount of temporary support needs to be set up, further reducing the construction efficiency. Therefore, it has become a key technical problem to be solved in the field to develop a structural system that can meet the requirements of seismic resistance and wind resistance of high-rise buildings and maximize the utilization rate of building space and the efficiency of industrialized construction.
