钢结构抗侧力构件的连接计算与分析
|
摘要
构件拼接和连接是抗震性能化设计中十分重要的环节,其主导思想是连接的承载力应大于构件的承载力.根据理论和实际工程经验,将现行建筑抗震设计规范的钢结构抗侧力构件连接计算公式与一般设计中采用的构件与节点等强设计公式进行对比分析,结果表明:如现行建筑抗震设计规范中的节点极限承载力计算公式改用节点的承载力设计值大于构件的承载力设计值表达,则显得较直观和安全.
The matching and jointing of members is an important link in the the seismic performancebased design,whose dominant idea is that the bearing capacity of jointing should be larger than that of the members. Comparing and analyzing the connection calculation formula of steel structural lateral force resistant members in the current code for seismic design of buildings and the member and node design formula of general design,according to the theory and practical engineering experience,we draw the conclusion: if the limit bearing capacity calculation formula in the current current code for seismic design of buildings is expressed that the design value of node bearing capacity is greater than the design value of member bearing capacity,it will become intuitive and safe.
