摘要
本文是在考证有关历史资料及震害调查的基础上,对砖石古塔的抗震机制进行了探讨。分析了各种砖石古塔的结构特点与震害现象的关系,提出了对现存砖石古塔进行抗震鉴定的意见。并指出沿中轴线劈裂,是开洞空心砖塔震害的重要现象,以及以悬臂杆理论分析砖石古塔抗震性能的必要性和可行性。
This paper through the studing a lot of Literatures about earthquake in ancient China and investigating typical pagodas, points out that the main phenomenon of seismic damage in masonary pagodas with openings is splittingcrack on their neutural, plane along vertical axis of pagodas.
Also, it presents the principle to analysis stress of these kind of pagodas by contilever-beam model and the method to assess thier earthquake resistant capacity.
The paper consists of three parts:
1. Types and structural characteristics of chinese ancient masonary pagodas;
2. Seismic damages of ancient masonary;
3. Seismic resistant mechanism of ancient masonary pagodas.
