中文摘要：
针对施工期钢筋混凝土结构的特点,分阶段地对影响施工期结构构件抗力的特征及其概率模型进行了研究,建议了施工期荷载随时间及空间变异的概率模型.基于动态模型,提出了考虑各个施工阶段相关性的结构可靠度阶段分析法,以矩形梁为例计算了工程实例.
英文摘要：
Based on the features of reinforced concrete structures during construction, the features and the factors which influence the construction resistance of structural elements are studied, and the probability model of the resistance is suggested. The probability models of the construction loads in space and time are proposed separately. Based on time-dependent reliability model, reliability analysis method is proposed for structural elements according to the stages of construction.
