对4个带楼板的钢管混凝土柱连接进行抗震性能分析,包括2个内部和2个外部节点。研究目的主要是对台湾地区广泛采用的钢梁组合楼板的性能进行分析。其次对梁末端楔形翼缘或者较大剪切键等连接处的抗震性能也进行了研究,以避免如Northridge地震后出现的那种不可预料的脆性破坏导致的梁翼缘焊缝完全熔透。此外,通过试验研究,推导了评估此类节点连接力-变形特性的分析模型。同时还对板域剪力转换区的楼板作用进行了研究。
Seismic performance analysis of four concrete-filled steel tubular column connections includes two internal and two external nodes. The main purpose of this study is to analyze the performance of the composite floor slab widely used in Taiwan. Second, the seismic performance of joints such as the wedge-shaped flange at the end of the beam or the large shear bond was also studied to avoid complete penetration of the weld of the flange of the beam caused by the unforeseen brittle failure that occurred after the Northridge earthquake. In addition, through the experimental study, the analytical model for evaluating the connection-deformation characteristics of such joints has been derived. At the same time, the effect of floor slab shear-transfer zone floor was also studied.
