Abstract

Purpose Basically, connections are used to transfer the force supported by structural members to other parts of the structure. The flush end-plate bolted beam to column connection is one type that has been widely used because of its simplicity in fabrication and rapid site erection. The purpose of this study is to determine the moment-rotation curve, moment of resistance (MR) and mode of failure, and the results were compared with existing results for normal flat web connections. Design/methodology/approach In this study, the connection modeled was the flush end-plate welded with triangular web profile (TriWP) steel beam section and then bolted to a UKC column flange. The bolted flush end-plate semi-rigid beam to column connection was modeled using finite element software. The specimen was modeled using LUSAS 14.3 finite element software, with dimensions and parameters of the finite element model sizes being 200 × 200 × 49.9 UKC, 200 × 100 × 17.8 UKB and 200 × 100 with a thickness of 20 mm for the endplate. Findings It can be concluded that the MR obtained from the TriWP steel beam section is different from that of the normal flat web steel beam by 28%. The value of MR for the TriWP beam section is lower than that of the normal flat web beam section, but the moment ultimate is higher by 21% than the normal flat web. Therefore, it can be concluded that the TriWP section can resist more acting force than the normal flat web section and is suitable to be used as a new proposed shape to replace the normal flat web section for a certain steel structure based on the end-plate connection behavior. Originality/value As a result, the TriWP section has better performance than the flat web section in resisting MR behavior.

研究使用三角形腹板型钢截面的梁柱连接

目的基本上，连接用于将结构构件支撑的力传递到结构的其他部分。平端板螺栓连接梁柱是一种因其制造简单、现场安装快速而被广泛使用的连接形式。本研究的目的是确定弯矩-旋转曲线、阻力矩（MR）和失效模式，并将结果与正常平腹板连接的现有结果进行比较。设计/方法/方法在本研究中，建模的连接是用三角形腹板型材（TriWP）钢梁截面焊接的平端板，然后用螺栓连接到UKC柱法兰上。采用有限元软件对螺栓平齐端板半刚性梁柱连接进行了建模。使用LUSAS14.3有限元软件对试样进行建模，有限元模型尺寸和参数分别为200×200×49.9 UKC、200×100×17.8 UKB和200×100，厚度为20 端板为mm。结果表明，TriWP钢梁截面的MR值与普通平腹钢梁的MR值相差28%。TriWP梁截面的MR值低于正常平腹板梁截面，但极限弯矩比正常平腹板高21%。因此，可以得出结论，基于端板连接行为，TriWP截面比普通平腹板截面能够承受更大的作用力，适合作为一种新的形状来代替某钢结构的普通平腹板。独创性/价值因此，TriWP截面在抵抗MR行为方面比平腹板截面具有更好的性能。
