摘要
门式刚架的中柱设计中,常因为平面外计算长度较大,所选实腹式截面无法满足平面外稳定验算,从而导致用钢量增加。文中针对设有吊车梁的门式刚架中柱,对3种设计方案进行比较,证明利用吊车梁设置隅撑,为中柱提供可靠侧向支承点,从而减小其平面外计算长度,该方法最经济实用。
In the mid-column design of gabled frames, the selected solid web section, isn＇t satisfied by in-plane stability checking because of the biggish out-plane effective length. Aiming at mid-column with crane beam in gabled frames, three projects are compared to prove that it is most economic to take advantage of the crane beam to setup knee bracing as the reliable lateral support, thereby to minimize the out-plane effective length. The calculate method hereinto can be referenced and discussed.
