淮阳太昊陵统天殿斗栱是豫东地区明清时期斗栱的典型代表,为了指导其修缮与加固,选取统天殿柱头科斗栱建立有限元分析模型,采用接触非线性理论并考虑大变形对其进行受力性能分析。分析结果表明:在承载力极限状态的竖向荷载作用下,斗栱沿荷载作用方向刚度较大,变形较小;斗栱的坐斗、各昂及栱的跨中易发生横纹受压破坏;单才万栱及头昂的跨中受拉区易发生剪切破坏;斗栱中各构件接触面的边缘部位易发生应力集中。研究结果将为统天殿斗栱的修缮设计提供科学依据,并为同类斗栱的修护提供技术参考。
In order to guide the repair and reinforcement of the temple in the Ming and Qing Dynasties in the eastern part of Henan Province, the Huidian Taihao Mausoleum Hall of Heaven Temple was chosen as the typical representative for the Ming dynasty. Using the nonlinear theory of contact and Considering the large deformation of its force analysis. The analysis results show that under the vertical load of ultimate bearing capacity, the stiffness of bucket 栱 along the direction of load is larger and the deformation is smaller. The buckets of bucket,, ; Only a million Wan and Tau span of the mid-span of the shear prone to shear damage; bucket joints in various parts of the contact surface prone to stress concentration. The results of the study will provide scientific basis for the repair and design of the temple of Tongti Temple and provide technical reference for the repair of similar doujinshan.
