摘要
青海坎布拉大佛工程总高99.9m,分为下部基座和上部佛像两部分。其中上部72m高佛像采用钢框架支撑体系。对位于佛像颈部的关键节点进行了有限元分析,了解节点应力状况,找出影响节点受力的关键因素,然后改进节点构造并进行验证,从而确保关键节点满足"多遇地震弹性、设防烈度地震弹性"的性能设计目标,可为类似钢结构节点设计提供参考。
Kanbula Buddha in Qinghai,with the height of 99.9 meters,consists of the lower base and upper Buddha.Steel frame-braced system was applied to the upper Buhhda of 72 meters in height.A finite element method(FEM)analysis on the key joints of the Buddha neck was conducted to obtain the stress distribution and the key factors influencing the performance of joints.Based on the results,geometric structure of the key joints was optimized and verified by FEM.The performance of modified key joints could meet the needs of performance-based design under small and medium earthquake.The results of the analysis could provide reference for the design of similar steel joints.
