摘要

在装配整体式结构中,连接节点部分比较重要且受力较为复杂。通过对新型外包钢板箍连接节点(钢板箍和钢板箍+栓筋的两种连接方式)进行单向反复加载试验,与现浇构件对比其承载力、变形能力、延性性能等整体工作性能;分析出装配整体式结构中连接节点正截面的破坏机理和工作性能,为其在工程中和其他方面的运用提供一定的参考。
In the prefabricated structure,the nodes were in the complex force condition and its always were the weak part.Therefore,the new connection,the connections were surrounded by steel cover plates,was taken the monotonous repeated loading test experiment and the results were compared with the cast-in-situ component in the area of carrying capacity,deformation capacity,ductility and deformation properties.The failure mechanism and working performance of the normal section was also analyzed.finally,the best configuration was given by changing certern parameters of the nodes which sourrounded by steel cover plates in order to prove certern evidence for its design in the engineering.
