Analysis On Shear Resistance Behavior Of HPS-HPC Composite Beams

Based on the analysis of steel-concrete composite beam on and abroad, the shear reasistant behavior of the HPS-HPC composite beam is analysed and researched.The main content is as follows: the development and application of the HPS ,HPC and composite beam are introduced Firstly,and the performance of the composite beam is also introduced in detail,which provided the foundation for the analysis of the composite beam; the calculational methods and experiential formula about the lognitudinal shear resistance and vertical shear resistance have been sum up in the chaper Two; the test,work mechanism,crab mode and carrying capacity of the stub are also introdeced,which provided the foundation for the next step.The sample which have been tested by Qinghua University are simulated and validitied by Ansys software in the same condition,then two HPS-HPC composite beams and the two commons are founded respectively for analysing their capacity , distortion ,shear capacity and slippage of the stub;Lastly six HPS-HPC composite beams which have six different connections are founded and analysed,the result showed that the carrying capacity ,distortion and slippage of the HPS-HPC composite beam can be affected by the connection of the stub clearly, and the effect is also showed,which can offer the referrence for design and application in practice.
