摘要
采用弹性理论的方法,考虑轴向力的影响,以杆件变形后的状态为依据建立平衡方程,探讨了轴向压力对框架结构动力性能的影响。通过一个算例分析,表明当轴向压力较大时,轴力对结构动力性能的影响不可忽略。
The equilibrium equations are developed based on the elastic theory and the deformation of bar elements. The influences of axial force on dynamic characteristics of steel frame construction are analyzed. Through a calculated example, it is shown that the influence of the axial force on dynamic characteristics of the construetion is not negligible when the axial force is relatively great.
