摘要
进行古建筑的维修加固,首先要确定的就是施加于结构或构件上的作用,然后通过作用效应与其承载力相比,才能确定该结构或构件能否继续使用或需经加固后继续使用。施加于结构上的作用直接影响维修加固方案的确定。对古建筑修缮设计基准期进行重新考虑,分别讨论了永久作用和可变作用对古建筑的影响,另外还对地震作用进行了研究,确定了木材及其加固材料的强度,为古建筑的维修加固提供了技术资料。
For the purpose of maintenance of historic buildings, the first step is to determine the load applied on the structure or member, and then calculate effects of actions. Compared with the bearing capacity, a structure or a member can be determined whether it can be used continually or it needs to be strengthened. The load applied on the structure directly influences the plan of maintenance. In this paper, design reference period for repairing is reconsidered, the effect of variable and permanent action on the historic buildings is discussed, in addition, the role of earthquakes is studied. At last, the strength values of timber and strengthening materials are determined, which provides technical data for maintaining the historic buildings.
