| 摘 要： | 现有钢筋混凝土构件的抗力时变模型,多是关于仅受弯的梁式构件,对偏压构件的考虑较少.针对此不足,首先分析了影响偏压构件抗力的各因素的时变模型.在此基础上,计算了不同参数情形下偏压构件抗力退化的若干数值特征,得出钢筋锈蚀后偏心距较大时抗力均值的下降程度会大一些,同时整个服役期内偏压构件的破坏模式可能会发生改变的结论.最后采...

| Abstract: | The current time dependent models of resistance for RC member are mainly on bending beam members,lacking enough consideration on reinforced concrete members subjected to eccentric compression.In order to overcome this disadvantage,first,the time dependent models of the factors influencing resistance for RC members subjected to eccentric compression were analyzed.Then,some numerical characteristics of resistance degradation for the members with different parameters were analyzed.It shows that with large ecce... |
