新型钢-混凝土组合板的力学性能研究

On performance of a new type of steel-concrete composite slab

以加劲肋形式、组合板厚度和栓钉布置为参数,进行了9块新型组合板的力学性能试验.试验结果表明,组合板的正截面承载力可按基于修正平截面假定的极限状态计算;组合板的跨中挠度,可在按现行规范计算的基础上,加上考虑界面滑移影响的附加变形值予以修正.

With the form of stiffening rib, the thickness of composite slab and the arranged mode of stud as parameters, the mechanical experiments are made on 9 specimens of a new type of composite slab. The result indicates that the normal section load-carrying capacity of the composite slab can be calculated by the limit state based on the amendatory plane cross-section assumption, and the deformation by the additional deform-ation value influenced by the interface slippage. The nonlinear property of the typical composite slab is analyzed by the software of finite element analysis based on the test results. The calculated values fit close to the experimented ones.
