| 摘 要： | 施工过程中的安全分析与控制要求对施工活荷载有较准确的估计。本文通过对一批钢筋混凝土结构在施工期间活荷载的现场调查、统计和分析,发现施工活荷载中堆积荷载是主要的,施工活荷载可以用指数分布描述,对指数分布的参数进行估计,并将施工活荷载转化为均布荷载。参照结构正常使用阶段荷载标准值的取法,给出了钢筋混凝土结构施工活荷载标准值的建议。研究结果可用于施工期结构的安全分析与控制,承包商也可以据此合理安排施工进度及现场材料的堆放。

| Abstract: | Safety analysis and control during construction require better estimation of live loads. In this paper, a survey on live loads of reinforced concrete buildings during construction has been conducted. It is found that stack load is the major live loads during the construction of reinforced concrete buildings and the live loads submit to exponential distribution. The parameters are estimated and the live loads are turned into uniform loads. Referring the method of choosing the standard value of loads in service phase, the standard value of live loads during construction is suggested. The results provide information on live loads in safety analysis and control of reinforced concrete buildings during construction. Contractors may arrange construction schedule and locate construction materials more reasonably, based on the information. |
