| 摘 要： | 对设有弯曲型支撑的钢框架结构的整体弹性稳定进行了分析,得到了理想状态下,弯曲型支撑框架结构的稳定方程.通过对r=0.5～1.0时的大量计算分析,得到了弯曲型支撑框架结构的临界相对支撑刚度Rth的近似计算公式.用有限元方法验证的结果表明,近似解析解具有足够的精度,该公式可以作为稳定计算时,框架有侧移和无侧移的判定准则.对弱支撑框架,本文给出了临界荷载和支撑刚度的关系.

| Abstract: | The elastic stability of steel frame with bending-type bracing system is studied in the paper Some formulae and tables for determination of the threshold stiffness of the bracing system are obtained A comparison is shown that the results of the proposed formulae are in good agreement with the results of finite element method The formulae may be used as a criterion to judge the sdiesway and no sidesway frame in the stability analysis When the stiffness of a bracing system is less than the threshold value,the relation between the critical load and relative bracing stiffness is discussed in detail in the paper |
