摘要
在总结大量已有研究文献的基础上,结合填充墙的破坏特点,提出了一种考虑填充墙作用影响的简化的框架结构有限元分析模型,该模型可以分别模拟墙体无洞口和有洞口的情况。通过进行精细有限元分析,给出了模型中关键参数的计算公式;考虑墙体开洞影响,给出了折减系数的计算方法。最后,结合实验结果对计算模型及参数的适用性进行了验证。
In this article,a new type of analysis model was given to calculate the influence of the infill walls in RC frame structures on the basis of the existing research literatures and the damage characteristics of the infill walls.The model can simulate the walls with and without holes.Through the fine finite element analysis,calculation formulae of the important parameters were put forward.In order to reflect the decrease of the stiffness of the walls with holes,stiffness influence parameter β was presented.Finally,combining with experimental results,the applicability of the model is verified.
