［提要］  施工期间钢筋混凝土结构的承力体系是由低龄期的混凝土构件和模板支撑系统组成。目前，采用有限元方法和简化方法来计算竖向荷载在混凝土构件和模板支撑间的分布。在有限元方法和简化方法的基础上，提出一种近似计算方法。根据施工过程，确定一些基本结构，通过有限元方法计算出基本结构中竖向荷载在混凝土构件和模板支撑间的分配系数，然后按照施工过程进行分析，能够简便地计算出施工期间混凝土构件和模板支撑所承受的荷载。

Approximate Method of Vertical Load Distribution Analysis of Reinforced Concrete Structures During Construction/Cong Shuping, Liang Shuting (College of Civil Engineering, Southeast University, Nanjing 210096, China)

Abstract:The bearing structure of reinforced concrete building during construction consists of formwork shores and early age concrete members. Now, the FEM and simple method are used to calculate the distribution of vertical load between concrete members and formwork shores. An approximate method is put forward to calculate the distribution of vertical load based on FEM and simple method. The primary structures are obtained according to the construction process. The coefficients of vertical load distribution between concrete members and formwork shores are confirmed through the FEM. The loads of concrete members and formwork shores could be obtained conveniently by the approximate method.
