某新型压型钢板抗弯承载力试验研究

Experimental Research on the Flexural Capacity of a New Profiled Steel Sheet

查阅大量文献发现,有关压型钢板的研究,对于压型钢板—混凝土组合楼板的抗弯性能、耐火性能等性能研究颇多,对于单一压型钢板性能研究较少。对单一压型钢板性能的研究是推广板材使用的前提,论文对某新型压型钢板进行抗弯承载力试验,通过量测压型钢板在荷载作用下的挠度变化以及荷载—应变曲线,得出此新型压型钢板在承载能力极限状态下的受弯承载力。

After consulting a large number of documents,it is found that there are many researches on the performance of profiled steel plate—concrete composite slabs,such as the bending performance and fire resistance of profiled steel plates,but less research on the performance of single profiled steel plates.The research on the performance of a single profiled steel plate is the prerequisite for the promotion of the use of plates.This article conducts a flexural bearing capacity test on a new profiled steel plate.Through measuring the deflection change of the profiled steel plate under load and the load—strain curve,it is obtained that the flexural capacity of this new profiled steel plate in the ultimate state of bearing capacity.
