摘要
稳定同题一直是钢结构设计的关键问题之一,整体失稳与局部失稳都是设计中应该避免的问题.钢结构梁柱节点是受力过程中、特别是地震作用时结构最薄弱的环节,而考虑节点的局部稳定性问题通常易被忽略.通过分析钢结构粱柱节点的稳定性问题,介绍了防止失稳的一系列措施以及屈曲后强度的利用,并对梁柱节点的复杂性研究进行了探讨.
Abstract
The stability problem is always the key problem of steel structure design,holidtic stability and partial instability should be avioded in the design.Beam-column joint of steel structure is the weakest tache in the course of stress,especially in the earthquake;But the problem of partial stability of joint is easy to be neglected,usually.The stability of beam-column joint was analysed,and a series of measures to avert instability and to take use of strength after-buckling were introduced,and the complicated research of beam-column joint was also discussed.
