中文摘要：
针对古木构件在保护和加固中的剩余寿命问题,提出了一种基于强度累积损伤理论的计算方法.同时,在多种因素综合作用下的截面时变模型的基础上,利用蒙特卡洛法,对构件的强度进行反算.得到具有一定可靠度指标的剩余寿命.与文献中的实例进行对比分析,验证该方法的可行性;通过2种不同的算例,得出了梁构件应该多注意裂缝的结论.
英文摘要：
For the problem of remaining life in the protection and reinforcement of ancient components,a calculation method based on the cumulative damage theory has been presented. On the basis of the crosssection model under a variety of factors based on the Monte Carlo method,the remaining life with a certain reliability index is obtained. The examples of the literatures have been compared to verify the feasibility of the proposed method. The comparison of two different examples shows that more attention should be taken in cracking for beam member.
