| 摘 要： | 基于现役结构的服役状态具有显著的时变性,提出增层改造项目必须考虑时间因素影响的观点。针对现今刚度可靠性分析处于相对匮乏的研究阶段,根据现役结构荷载、抗力的固有特点,考虑计算模式不确定性、材料性能劣化、构件几何尺寸损伤等多因素影响机制,对现役结构增层进行了动态可靠性分析,并给出了现役结构增层刚度影响因素的时变规律。

| Abstract: | Based on the distinct time-dependent feature of the structure service state,a viewpoint was presented that the aging effect on retrofit of the building by adding a storey must be considered.In view of the shortage of the reliability analysis on the stiffness,based on the intrinsic features of the loading and the resistance of the in-service structure,a dynamic reliability analysis was done for adding a storey onto an in-service structure.In the analysis many factors including the uncertainty of the calculat... |
