Problems solved by technology

[0004] However, the currently used liner concrete layout is almost full-section layout, which does not conform to the changing law of the vertical shear force near the fulcrum from large to small, which not only leads to a large amount of concrete used, but also reduces the efficiency of concrete and increases the The burden of construction, but also increases the weight of the structure, reducing the efficiency of applying longitudinal prestress

Abstract

The invention relates to a variable-cross-section corrugated steel plate-concrete combined plate structure. The combined plate consists of a variable-cross-section corrugated steel plate and lining concrete, wherein the lining concrete comprises three portions including a full-cross-section segment I, a transition-cross-section segment II and a minimum-cross-section segment III which are sequentially arranged along the longitudinal direction of the corrugated steel plate from a fulcrum to bear the shear force, which becomes small from large, of the corrugated plate in the longitudinal direction. The full-cross-section segment ensures that the top surface and the bottom surface of the corrugated steel plate are superposed to the top surface and the bottom surface of the concrete; the transition-cross-section segment II smoothly connects the full-cross-section segment I with the minimum-cross-section segment III; by the minimum-cross-section segment III, the buckling strength of the cross section of the combined plate is improved, and finally, the combined plate structure with light weight, strong shear resistance and good buckling stability is obtained.

Description

technical field [0001] The invention belongs to the field of steel-concrete composite structures, in particular to a variable-section corrugated steel plate-concrete composite structure. Background technique [0002] The shear strength and stability of corrugated steel plates are important issues in the design of corrugated steel composite structures. The shear force of the corrugated steel plate composite structure is relatively large near the fulcrum, and the structural conditions and constraints at the fulcrum are generally more complicated. Moreover, the longitudinal stiffness of the corrugated steel plate is relatively small. When the composite structure is formed with concrete, the corrugated steel plate bears almost all the shear force of the section, so the shear deformation is very significant. [0003] In order to improve the buckling resistance and stability of the corrugated steel plate, and at the same time make the stress of the corrugated steel plate uniforml...
