| 摘 要： | 钢筋混凝土结构在施工阶段实际上是一个部分完成结构和模板支撑系统构成的“时变结构”.经验表明,随着模板支撑系统的撤换,这种“时变结构”很可能处于整个“生命周期”中最不安全的受力状态,从而引发事故.近些年来,环境日夜温差对结构安全的影响逐渐得到重视.本文在国内外相关研究的基础上,提出了新的考虑日夜环境温差影响的钢筋混凝土框架、板柱和剪力墙结构在施工期的结构模型和分析方法,并编制了相应的“考虑温度影响的施工过程安全分析”（Safety Analysis during Construction considering Temperature,SACT）应用软件.

| Abstract: | The reinforced concrete structure during construction is a time-dependent structure which consists of a partly completed structure and a formwork-shore system.Experience shows that,as the formwork-shore system changes,the time-dependent structure may be under the most critical state during its lifecycle and accident may occur.In recent years,the effect of ambient temperature variation between day and night on the analytical results attracts more and more attention.In the present paper,a new structural model and analysis methods for reinforced concrete frames,slab-column systems,and shear wall structures is proposed based on related researches,and a new software named Safety Analysis during Construction considering Temperature （SACT） is programmed. |
