根据现场调查结果,对带有半刚性节点的墙体、屋面、楼板、木骨架等构件的结构形式进行了研究。对布达拉宫典型三层结构单元进行了数值模拟研究。研究了El-Centro地震波作用下结构的加速度响应。结果表明,节点的布置有利于提高结构的抗震性能。总结了结构构件的典型损伤问题,分析了造成结构构件损伤的主要原因。讨论了可实施的不同修复方法,为结构的维护提供参考。
Tibetan ancient timber structure has great historical, cultural, artistic, and scientific values. The structural configuration of members such as wall, roof, slab, and timber skeleton with semirigid joints is studied in this paper based on field survey results. The aseismic characteristics of Tibetan ancient timber structure have been summarized and introduced. One of the unique features of the Tibetan ancient timber structure is its special beam-column joint which has a semirigid behavior. Numerical simulations of a typical 3-storey structural unit in the Potala Palace are studied. The acceleration responses of the structure under the action of El-Centro seismic waves are studied. Results show that the arrangement of the joints is helpful for seismic resistance of the structure. Most Tibetan ancient timber structures are suffering from different types of damage to certain extent which is vulnerable to seismic actions. Typical damage problems of the structural components are summarized and the main causes of this damage are analyzed. Different rehabilitation methods that can be implemented are discussed, providing references for maintenance of the structures.
