A REPEATEDLY LOADED EXPERIMENTAL STUDY OF BEAM-PILLAR SUPPORTED JOINT IN LARGE COAL-FIRED POWER PLANTS

摘要: 以发电厂厂房钢结构中普遍采用的梁-柱-支撑节点为对象,介绍了其反复加载试验研究。根据工作点的不同,设计了3个试件,研究了梁-柱-支撑节点的强度和滞回性能,并对斜支撑及节点板进行受力分析。研究结果表明,该类节点具有较好的抗震能力,工作点的不同可导致节点承载能力的区别。

Abstract: A repeatedly loaded experiment of beam-pillar supported joint widely used in steel structure workshop was introduced. Three specimens of different working places were studied. The strength and hysteresis behavior were obtained and the stress analysis of slanting brace and joint board was carried out. The result showed that this kind of joint had good aseismic ability. The joint has different load carrying capacity in different working places.
