摘    要:提出了一种波纹腹板H型钢梁与普通H型钢柱采用端板螺栓连接的节点构造.基于高强螺栓抗拉性能的刚性端板模型和T形连接件理论,提出波纹腹板H型钢梁柱端板螺栓连接节点的设计方法.进行了2个波纹腹板H型钢梁柱端板螺栓连接节点的静力试验,并使用商用有限元分析软件ABAQUS建立节点的有限元模型,将设计弯矩下的高强螺栓最大拉力的试验结果与有限元计算结果进行对比,证明了高强螺栓拉力计算公式的可靠性;通过对比设计弯矩和有限元计算的端板屈服弯矩,证明了端板厚度计算公式的合理性.

关 键 词:波纹腹板H型钢  端板连接节点  静力性能  试验研究  有限元方法

Abstract:Bolted end-plate connection is proposed as beam-to-column rigid connection between H-beams with corrugated webs and common H-columns. Based on rigid end-plate model and T-stud method on tensile performance of high-strength bolts, designing method for bolted end-plate connections of H-beams with corrugated webs is proposed. Then 2 static tests of beam-to-column bolted end-plate connections of beams with corrugated webs have been conducted, and finite element (FE) analyses of the specimens have been carried out using the commercial software ABAQUS. The maximum tension in bolts under designing moment from test results and FE analysis are presented, which proves the designing method for high-strength bolts to be secure. The designing moment is compared with the end-plate yielding moment, which proves the reliability of designing method for end-plate.
Keywords:H-beams with corrugated webs  bolted end-plate connections  static behavior  experimental investigation  finite element analysis
