EXPERIMENTAL STUDY OF THE BEARING CAPACITY OF LONG SPAN PROFILED STEEL SHEET CONCRETE COMPOSITE SLABS

Through the experiments of four concrete composite slabs under static loading to compare their flexural properties (deflection, bearing capacity, failure mode), this paper discusses the influence of composite slabs flexural behavior on different length of additional bars and sectional effective height. The results showed that they will improve the bearing capacity effectively by reasonably increasing the sectional effective height and controlling the length of additional bars.

The Stability

This paper presents a study aimed to estimate the flexural performance of profiled steel sheet-bamboo plywood composite slabs as a first step to evaluate its potential application as structural components. Nine specimens were tested to investigate the stability of steel-bamboo composite structure. According to different connection methods, three types of composite slabs were discussed, including pure bonding slabs (PBSs), composite bonding slabs (CBSs), and reinforced composite bonding slabs (RCBS). The result showed that specimens employed multiple composite methods (RCBS) exhibited excellent flexural bearing capacity and stiffness compared with PBS. The increase of bamboo plywood thickness could improve bearing capacity and flexural stiffness of composite slabs, while the reduction of screw spacing could enhance the bearing capacity and ductility of composite slabs. The RCBS, which can provide higher bearing capacity and stiffness and possess excellent deformation capability, are well worth of research and practical application.

Composite Slabs

In this research, a kind of composite cement plates are utilized as permanent formworks, and poured concrete together to form composite slabs. Through static test of composite slabs with different bonding modes of interface between formwork and concrete, bearing capacity, deformability and cooperation states of concrete and composite formwork are studied. Through static test of composite slabs with splicing joints formworks at different positions, bond quality near the splicing joints are observed visually, stress nature and deformability variations resulted from different splicing joint positions of formwork are analyzed. And meanwhile, stress and deformability of the ordinary concrete slab without formwork is researched under the same conditions. Through above experiments, acting as a part of the slab, how composite formwork influence bearing capacity and deformability of the combined slab is investigated.
