组合楼盖在水平荷载作用下受力性能研究

钢-高效预应力叠合板组合楼盖是一种新型楼盖,分别利用试验分析方法和有限元分析方法来验证这种新型楼盖在水平荷载作用下具有较好的受力性能.在试验分析中,对叠合板组合楼盖的设计方面的问题进行了理论分析,并得到了板上与板下的应力分布图,沿梁纵向的滑移分布图,栓钉处的滑移曲线等等.在试验分析的基础上,对一榀组合楼盖进行了水平荷载作用下的有限元模拟分析.最后对试验数据和有限元分析结果进行比较,表明试验数据与理论分析结果吻合良好,并得到了几点对实际工程有重要指导意义的结论.

Research on mechanical behavior of composite slabs under horizontal load

The steel-high efficient Prestressed Concrete Composite Slabs is a new type of slabs.To study the mechanical behavior of the Composite Slabs under horizontal loading,the experimental analysis and the finite element simulation analysis are applied.In the experimental analysis,the theoretic analysis is discussed on how to design the steel-high efficient Prestressed Concrete Composite Slabs,and obstained the steain distribution at the top and the bottom of the slabs,longitudinal slid curve os specimen,slid curve of specimen at the studs and so on.Then based on the experiment,the finite element simulation analysisare carried on to study the preferable capability of Composite slabs under horizontal loading.Finaly,the experimental results are compared with the calculated results,and they agreed with each other.And those conclusions drawn from the results can be useful to practical engineering.
