摘要
钢筋桁架混凝土叠合板在施工阶段容易产生较大的挠度,严重的会产生裂缝,因此精确计算叠合板的挠度尤为重要。基于钢筋混凝土板和钢筋桁架的刚度叠加理论,提出了一种施工阶段的挠度计算方法。通过与实验结果对比,证明计算方法具备一定的可行性和可推广性,为施工支撑架设提供了理论计算依据。
Reinforced truss concrete composite slab is prone to produce large deflections during construction and produces serious cracks.Therefore,it is important to calculate the deflection of the composite slab accurately.Based on the stiffness superposition theory of reinforced concrete slab and steel truss,a deflection calculation method is proposed in the construction stage.Compared with the experimental results,it is proved that the calculation method has certain feasibility and generalization,which provides the theoretical basis for the construction support.
