【摘要】 用解析法研究了横向载荷和初始挠度对梁柱结构稳定性的影响,提出预拱度可以有效抵制横向载荷对结构稳定性的不利影响。在此基础上,通过解算横向载荷与初始挠度对梁柱稳定性的影响系数——综合因子n取值范围的计算,解决了强度稳定综合理论方法预测结构稳定性的部分难题。更多还原

【Abstract】 In this paper,the influencing of lateral load and initial deflection are studied with analytic method on stability of beam-to-column.It is put forward that the pre-arch can effectively enhance structural stability when lateral load exist.On this basis,comprehensive factor n value scope is calculated which is lateral load and initial deflection’s influence coefficient.It solves the problem that designers forecast the structure stability by Combine Theory of Strength and Stability.更多还原
