该文以研究外壳核心现浇预制装配式钢筋混凝土T型边节点的抗震性能为目的,制作一个新型装配式边节点和一个现浇边节点,开展两个T型节点抗震性能的低周反复试验,考察并分析比较采用两种不同施工方法的T型边节点的破坏形态、滞回特性、位移延性、能量耗散、刚度退化等抗震性能,研究表明新型装配式T型节点与RC现浇T型节点相似,具有良好的整体性和抗震性能,可以满足RC框架结构的抗震设计要求。
In this paper, a new type of fabricated edge node and a pour-on edge node are fabricated for the purpose of studying the seismic performance of cast-in-situ precast prefabricated reinforced concrete T-edge joints. Two low-cycle repeated tests of seismic behavior of T-joints , The seismic performance of the T-shaped edge joints with two different construction methods was investigated and compared, such as failure mode, hysteretic behavior, displacement ductility, energy dissipation and stiffness degradation. The results show that the new type of T-joints with RC cast-in-place Type nodes are similar, with good integrity and seismic performance, to meet the seismic design requirements of RC frame structure.
