联建房具有外观造型协调统一、节约土地资源、减少建设成本等优点,是农村现代化发展的产物,值得在全国村镇进行推广。目前,联建房在福建省宁德地区大量建设,形成闽东地区的特色民居。由于部分业主因资金短缺等因素缓建部分单元,采取的施工预留措施使结构形成竖向不规则结构。结合具体工程实例通过3种施工工况的抗震性能比较,房屋结构刚度下降,整体性差,抗震性能削弱。对其施工措施提出合理的抗震构造要求,并供同类工程参考。
Building with the appearance of building coordination, conservation of land resources, reduce the cost of construction, etc., is the product of the modernization of rural areas, it is worth in the country to promote village and town. At present, the United Building in Ningde, Fujian Province, a lot of construction, the formation of the characteristics of residential areas in eastern Fujian. As part of the owners due to lack of funds and other factors to ease the construction of some units, the construction reserve measures taken to the structure of vertical irregular structure. According to the comparison of the seismic performance of the three construction conditions with the concrete engineering example, the rigidity of the house structure is decreased, the integrity is poor and the seismic performance is weakened. Put forward reasonable seismic structural requirements for its construction measures and provide reference for similar projects.
