| 摘 要： | 对我国几本钢结构设计规范 (程 )中格构式压弯杆的平面内稳定计算公式与数值分析的结果进行了对比 ,定量地说明了当前格构式柱子平面内稳定性计算公式存在偏不安全的问题。根据数值分析结果 ,建议对格构式压弯杆采用与实腹式压弯杆相同的计算公式。

| Abstract: | Several formulas calculating the in-plane stability of latticed columns under compression and bending in each design code for steel structures are compared with numerical results,and it is found that the current formula is unsafe when the slenderness is large.It is suggested that the same formula for in-plane stability of I-section beam-columns may be used for latticed beam-columns. |
