| 摘 要： | 考虑混凝土结构和模板支撑体系的主要失效模式，提出施工期混凝土结构可靠度分析方法。利用施工现场调研统计资料和试验数据，研究钢筋混凝土结构和模板支撑体系在施工过程中的抗力和荷载的概率模型，计算出不同支模方案对应的施工期钢筋混凝土结构体系可靠度，并分析施工活荷载统计参数对模板支撑体系可靠度的影响。 |
| 关 键 词： | 钢筋混凝土结构 施工 模板支撑 体系可靠度 |

| Abstract: | Making full use of site investigation and references,probabilistic models of loads and resistances during building construction were presented.In view of the significant failure modes of formwork-supporting system and reinforced concrete member,the reliability of time-dependent system during the construction of typical multistory reinforced concrete buildings was developed.The influences of the number of levels of shoring/reshoring and live load during construction of the building on system reliability were included in the analysis. |
| Keywords: | reinforced-concrete building construction formwork-supporting system system reliability |
