摘要
建立一个有效的数值分析模型,模拟槽钢剪力连接件的性能。重点研究单调加载下槽钢剪力连接件的抗剪能力。通过试验数据证实模型是有效的,引用加拿大设计规范CAN/CSA-S16-2001和GB50017-2003《钢结构设计规范》中给出的公式进行对比。利用该非线性模型进行的研究表明:混凝土强度、槽钢腹板和翼缘厚度、槽钢高度以及槽钢的长度对槽钢剪力连接件的承载力有较大影响,混凝土块高度的影响较小。
An effective numerical model is proposed to simulate the property of channel shear connectors.The focus is on the shear capacity of channel shear connectors under monotonic loading.The model has been validated against test results and compared with data given in CAN/CSA-S16-2001 and GB 50017-2003 Code for Design of Steel Structures.The results show that the concrete strength,web and flange thicknesses of the channel,height of the channel section and the length of the channel are significant parameters in determining the bearing capacity of channel shear connectors,whereas the height of the concrete is not a significant parameter.
