摘　　要：砖木结构房屋在我国农村地区广泛使用,而这种房屋普遍无抗震设防构造措施。木屋架、檩条及其他相关构件之间没有可靠连接,在竖向、水平地震力作用下极易脱落、破坏,造成结构的整体或者部分坍塌,进而产生较大灾害。结合实际工程,对木柱作为竖向承重体系的典型结构进行了结构抗震技术优化研究。研究结果表明,对于无抗震构造措施的既有农村砖木结构,抗震加固技术优化后的结构体系不仅能够满足本区域的抗震设防要求,而且经济效果明显。Brick-wood houses are widely used in rural in China with no earthquake-proof housing construction measures in general. Wooden frame structures, crossbeam and other related components have no reliable connections, which are easily fell off and destroyed by vertical and horizontal earthquake force. Combined with actual project, the structural seismic technology optimize study on the typical structure of wood column as the vertical load-bearing system are introduced, the study results show that the structure system with the seismic reinforcement technology optimization can meet the seismic requirements of the region, and the economic effect is good.
