不同规范对现浇混凝土结构侧模板水平荷载规定的差异分析

Analysis of the Difference of the Torizontal Load Regulations of the Side Formwork of Cast-in-situ Concrete Structures in Different Codes

在制定现浇混凝土结构模板专项方案实践中,对侧模设计、安装影响较大的是不同施工工况的水平荷载,但铁路、公路、建筑行业规范对水平荷载效应组合值的计算规定,存在一定差异,在使用时难以准确理解掌握,通过梳理、比较不同行业规范的差异及其原因分析,提出了在计算侧模水平荷载组合设计值时的处理原则、方法。

In the practice of formulating the special scheme of cast-in-place concrete structure formwork,the horizontal load of different construction conditions has a greater impact on the design and installation of side formwork.However,there are regulations on the calculation of the combined value of the horizontal load effect in the railway,highway,and construction industry codes.Certain differences make it difficult for practitioners to accurately understand and master.This article sorts out the differences between different codes and regulations for the calculation process of the horizontal load effect combination value,and conducts an inductive analysis on it,and proposes processing principles and methods.
