双钢板-混凝土组合构件面外受力性能研究综述

Review of study on the out-of-plane mechanical performance of steel-concrete-steel sandwich composite members

主要对双钢板-混凝土组合构件面外受力性能的相关研究进行综述。从影响因素和承载力计算两方面介绍了国内外有关双钢板-混凝土受弯性能、受剪性能、受压性能的研究成果。总结相应的设计方法,介绍相关规范,重点对有关抗震性能的研究进行分析。通过对收集到的现有试验数据进行拟合及概率分析,提出对应不同保证率的屈曲应力计算公式;指出双钢板-混凝土组合构件研究中存在的若干问题,展望研究前景。

The research on the out-of-plane mechanical performance of steel-concrete-steel sandwich composite members was reviewed.The research results of flexural performance,shear performance and compression performance at home and abroad were introduced from two aspects:influencing factors and bearing capacity calculation.The corresponding design methods were summarized,the relevant codes were introduced,and the research on seismic performance was mainly analyzed.Through fitting and probability analysis of the collected existing test data,the calculation formulas of buckling stress corresponding to different guarantee rates were proposed.Some problems existing in the research of steel-concrete-steel sandwich composite members were pointed out and the research prospect was prospected.
