Abstract:
Modularized construction is a new type of prefabricated building system with green environmental protection and excellent performance. There are few studies on the seismic performance of its key connection joint. This paper presents a new type of assembled connection joint for the high-rise modularized construction. Cyclic shear tests of full-scale joints were carried out, and the key indexes of their seismic performances including the hysteretic performance, ductility, and energy dissipation capacity were analyzed and obtained. The results show that the hysteresis loops of longitudinal and lateral cyclic shear tests were both plump in shapes. The ductility coefficients were 4.54 and 4.98, and the energy dissipation coefficients were 1.83 and 1.43, respectively. The test joint had good ductility and energy dissipation capacity. The positions of yield failure of specimens were mainly concentrated in the connection areas between the column and short beam or end-plate. The research can provide the technical reference for the seismic design and engineering application of related modularized constructions.

摘要

模块化建筑是一种绿色环保、性能优良的新型装配式建筑体系,其节点抗震性能的研究比较欠缺。本文针对高层装配式模块化建筑体系,设计一种新型装配式连接节点,完成了三个足尺节点拟静力试验,分析并获得了节点面内、面外的滞回性能、延性及耗能能力等抗震性能关键指标。研究结果表明,长轴向和短轴向面内抗剪拟静力试验滞回曲线较为饱满,延性系数分别为4.54和4.98,能量耗散系数分别为1.83和1.43,节点在平面内具有良好的耗能能力和延性;试件发生屈服破坏的位置主要在柱与短梁连接部位及柱与端板连接的部位。本研究可为相关装配式模块化建筑的抗震设计和工程应用提供技术参考。
