RESEARCH AND APPLICATION ON ASEISMIC ENERGY-SAVING STRUCTURAL SYSTEM FOR RURAL BUILDINGS

  • 摘要: 我国村镇建筑多数为农民自建,抗震能力较差,节能技术落后,历次地震村镇建筑破坏严重,亟待研发低成本村镇建筑抗震节能结构体系。分析了传统村镇建筑生土墙体承重结构、土木混合承重结构、木结构、石结构、砖砌体结构特点,以及抗震建筑节能技术现状。介绍了课题组近年研发的多种低成本村镇建筑抗震与隔震结构,包括带竖向构造钢筋再生混凝土砖结构、带构造柱保温承重混凝土砌块结构、玻璃丝布-石墨隔震砌体结构、玻璃珠砂浆隔震砌体结构和异形柱边框保温模块单排配筋剪力墙结构及其工程应用情况。研究表明:该文提出并研发的村镇建筑低成本抗震与隔震结构,施工简便,经济适用,抗震节能效果好。结合村镇建筑产业化技术研发、生态环保建材应用和绿色施工需求,指出了村镇建筑抗震节能结构体系发展的关键问题。

     

    Abstract: Rural buildings in China were mostly self-built by farmers and destroyed severely after earthquakes due to poor aseismic capacity and inefficient energy saving measures. Thusly, it is an urgent need to develop an aseismic energy saving structural system with low-cost rural construction. The paper analyzed the characteristics of traditional rural building structures, including raw soil wall bearing structure, soil-wood bearing structure, wood structure, stone structure and brick masonry structure, as well as their status quo on the energy saving technologies for aseismic buildings, respectively. The research on the low-cost aseismic and isolation structures for rural buildings by the author’s group in recent years were introduced, which include a RAC brick masonry structure with vertical constructional reinforcements, a new type concrete block masonry structure with constructional columns, an isolated masonry structure with glass fiber cloth and panels-graphite-glass fiber cloth panels layer, an isolated masonry structures with low-strength glass bead mortar layer, a RAC shear wall with heat insulation blocks and a single layer of reinforcements, as well as the corresponding engineering applications. The studies show that the aseismic and isolated structures proposed above have the advantages of being constructed easily, economical and applicable to use, and good aseismic energy saving effect. Combined with the demand of industrialization application technology development for rural buildings, the application of the ecological environmental protection materials, and green construction, the key problems were pointed out for the development of a structural system of rural aseismic energy saving construction.
