摘要
对包括栓钉和PBL剪力键在内的3大类11子类共33个试件进行试验研究,并将模型试验与有限元仿真分析相结合,主要开展以下几个方面的工作:研究PBL剪力键的传力机理、荷载-滑移规律及静载力学性能;分析PBL剪力键力学性能的影响因素;对比有限元分析结果与试验结果,分析采用非线性有限元分析来模拟推出试验的可行性;对比国内已有的典型推出试验的结果;对PBL剪力键的推出试验提出改进意见。
Model test is adopted to investigate the mechanical characteristics of 33 specimens in 11 sub-types and three types including stud and perfobond rib shear connectors. Combining the model test with finite element method, the main work has been done as follows： transmission mechanics, the load-slippage rule, mechanical property on dead-load have been researched, and the influencing factors for mechanical characteristics are analysed; the results of finite element method and typical push-out tests are contrasted, the feasibility of nonlinear FEM is analysed;and some recommendations of push-out test of PBL shear connector are presented.
