摘要:
通过实地调查,分析了大理、丽江地区木结构榫卯结构的配置情况以及二者结构上的差异。为了研究二者的抗震性能与受力特性,通过有限元软件对两个地区的典型穿斗式木结构山架进行低周往复荷载模拟。结果表明:丽江地区穿斗式木结构山架抗震性能优于大理地区,两地木结构的薄弱点均在横向构件与纵向构件的榫卯节点处,榫卯节点的薄弱点位于榫头末端,二者的抗侧刚度均不高,易在水平荷载下倾斜。
Abstract:
Based on field investigation of the residential houses in Dali and Lijiang of Yunnan province,we analyze the difference of the tenon structure of the column-and-tie timber structures between the two places.In order to study the seismic performance and stress characteristics of the timber structure in the two places,we use the finite element analysis software to simulate the low-cycle reciprocating load to the gable-shaped frame of the column-and-tie timber structure in the two places.The results show that the gable-shaped frame in Lijiang has better seismic performance than that in Dali.The tenon joint of the transverse member and the longitudinal member is the weak part of the timber structure in both Dali and Lijiang,the end tenon is the weak part of the tenon joint.The gable-shaped frame in both Dali and Lijiang have low lateral stiffness,and they are apt to tilt under the lateral load.
