摘要
研究了钢筋混凝土底层框架结构在水平荷载和竖向荷载共同作用下的二阶效应,通过简化的计算模型,建立了考虑二阶效应的平衡方程,在一阶效应内力计算的基础上,通过修正系数对其内力进行修正,从而体现二阶效应影响,并分析了影响二阶效应的主要因素。
The internal force should be analyzed considering second-order effect in reinforced concrete structure of bottom story frame under horizontal load and vertical load.The equilibrium equation considering second-order effect was established by simplifying calculation model.The internal force was corrected with correction coefficient on the basis of the internal force calculation of first-order effect,which embodied affection of second-order effect and analyzed the major factors of affecting second-order effect.
