Next, we conducted a sample survey in four townships： Huji, Shipai, Zhangji, and Jiuli. According to the census and sample survey data of the rural residence buildings, we evaluated the quality and earthquake-resistant performance of the rural buildings for the various local rural residential structural types. The results showed that there are four main factors affecting the seismic performance of the local rural residences ： （ 1 ） Foundations are not made appropriately （ such as by compaction or some other fill） but are built directly in the farming soil. （2） Seismic measures are not completely implemented. Structure construction measures are not in place at the junction of the vertical and horizontal wall. The vertical wall joints are not the result of the same masonry techniques as the horizontal joints. There are no lintels above the door and window openings, or if there are any, the length of the lintels is less than 240 mm. （3） The brick masonry wall has low strength. The greatest housing wall mortar strength is between M0. 4 - 1.5, much lower than the strength of the brick. （4） The building material and construction quality are poor. The quality of the mortar masonry wall is poor. The cracks between the bricks are uneven, even in the seams.展开更多
