摘要:
研究福建土楼外部夯土墙和内部木构架对土楼整体抗震性能的贡献,探讨方形和圆形土楼抗震性能的差异.采用有限元数值模拟方法,选取与福建土楼地质条件相近的两组天然地震波(EL Centro波和Taft波)和一组人工地震波,以圆形土楼承启楼和方形土楼世泽楼为例进行分析.分别对外部夯土墙和夯土-木构架混合结构进行计算,得到在地震作用下的应力、层间相对位移、层间位移角、木结构承受的水平地震剪力等性能指标.结果表明:地震力主要是由夯土墙的惯性力引起的,夯土墙占水平地震总剪力的97.4%;圆形土楼的应力和应变比方形土楼更均匀,空间整体性更好.
Abstract:
The contribution of external rammed earth wall and internal timber frame of Fujian Tulou to the overall seismic performance of Tulou was studied, and the difference in seismic performance of square and round Tulous was discussed. Using the finite element numerical simulation method, two natural earthquake waves(EL Centro wave and Taft wave)and one artificial earthquake wave were selected, which was similar to the geological conditions of Fujian Tulou. The round Chengqi Tulou and square Shize Tulou were analyzed. Calculating the external rammed earth wall and rammed earth-timber frame mixed structure separately, the performance indexes including stress, interlayer relative displacement, layer displacement angle and timber frame horizontal shear force were obtained. The results show that the seismic force is mainly caused by the inertial force of rammed earth wall, which accounts for 97.4% of the total horizontal seismic shear force. The stress and strain of the round Tulou is more uniform than the square Tulou, and the spatial integrity of the round one is much better.
