后加混凝土构件的加固方法是在原有砌体结构外部新增钢筋混凝土构件,形成一种新型的组合结构.本文提出了考虑连接节点的后加混凝土构件-砌体组合结构的简化理论计算模型,并推导了不同构件的等效计算公式.考虑均布分布荷载和倒三角分布荷载作用,对组合结构的变形、剪力分配进行计算分析.计算结果从定性方面验证了本文提出的简化计算模型的可行性和有效性.同时针对某实际工程进行理论计算,与三维空间模型在弹性阶段的计算结果进行对比,从定量方面验证了本文提出的简化计算模型的准确性.
The method of adding post-reinforced concrete members is to add new reinforced concrete members outside of the original masonry structure to form a new type of composite structure.This paper presents a simplified theoretical model considering post-added concrete members-masonry composite structures of connecting nodes, And the equivalent formulas of different components are deduced.The deformation and shear distribution of the composite structure are calculated and analyzed considering the distributed load and the inverted triangular load.The results of the calculation verify the simplified calculation model proposed in this paper Feasibility and effectiveness of the proposed method.At the same time, the theoretical calculation of a practical project is compared with that of the three-dimensional model in the elastic stage, and the accuracy of the simplified calculation model verified in this paper is verified quantitatively.
