不同波高的波折板连接件的抗剪性能试验研究

摘要

The corrugated perforated plate was a new type of shear connector.This paper presented the results from static push-out tests on six corrugated perforated plate connectors and two perfobond plate connectors,which had been designed and made.The effects of the different height of wave on shearing behavior were mainly studied.The load versus-slip curve,the load-stress curve,the load-strain curve of transverse rebar and the failure modes of the two shear connectors were obtained.The conclusions showed that the load versus slip curve of the corrugated perforated plate shear connectors approximately included no slip stage,the elastic stage and the plastic-developing stage.Increasing the height of wave could enhance the bearing capacity and shearing rigidity.Compared with the perforated shear connectors,the corrugated perforated plate shear connectors had advantages of higher bearing capacity,better slide-resistant behavior and ductility and so on.%波折开孔板连接件是一种新型剪力连接件。通过对设计、制作的6个波折板连接件和两个平开孔板连接件试件在单调静力荷载作用下的推出试验，主要研究波高不同对连接件抗剪性能的影响。得出了两种连接件试件的荷载一滑移曲线、荷载一应力曲线、横向贯穿钢筋的荷载一应变曲线及破坏形态。结果表明：波折板连接件的荷载一滑移曲线大致可分为无滑移阶段、弹性阶段和塑性发展阶段；其受剪承载力和抗剪刚度随着波高的增加而增大；与平板连接件相比，具有承载力更高、抗滑移性能更好、延性较好等优点。
