ABSTRACT

In Hollow Structural Section (HSS) column-beam-brace connections, offset between gusset plate and HSS column webs leads to large distortion and out-of-plane deformation in HSS column face. To alleviate such undesirable effect, this paper proposes a new connection which consists of concrete infill and gusset plate passing through HSS column, called Through-Gusset Plate (TGP).The results indicated that the proposed connection increases the lateral stiffness, lateral strength, and energy dissipation capacity of frame specimens by up to 74, 67, and 73%, respectively. Moreover, due to using this novel connection, the normal force component capacity of connection is enhanced by approximately 3.2 times.

摘要

在中空结构截面（HSS）柱-梁-支撑连接中，节点板与高速钢柱腹板之间的偏移会导致高速钢柱面发生较大的变形和面外变形。为了减轻这种不良影响，本文提出了一种由混凝土填充和节点板穿过高速钢柱组成的新连接，称为通孔节点板（TGP）。结果表明，所提出的连接增加了横向刚度、横向强度和框架试样的能量耗散能力分别高达 74%、67% 和 73%。此外，由于采用了这种新颖的连接方式，连接的法向分力能力提高了约3.2倍。
