抗震设防高烈度区异形柱结构设计应注意的两个问题

Two Important Questions About Structural Design of Special-shaped Columns in the High Earthquake Fortification Zones

讨论了抗震设防高烈度区异形柱结构设计中的框架节点抗剪验算和地震作用方向,提出需要通过节点抗剪验算来控制抗震设防高烈度区异形柱结构的适用高度。分析发现地震作用计算方向对异形柱配筋计算影响较大,并讨论了目前异形柱结构设计中存在的相应问题。

Two important questions about the structural design of special-shaped columns in the earthquake fortification zones are discussed. The shearing capacity checking computation of joint is the key factor on proper height decision. The direction of earthquake action greatly influences the bearing capacity checking computation of column with special-shaped section. And some problems in the structural design of special-shaped columns are analyzed.
