【摘要】：秸秆的利用方式有很多,包括造纸,焚烧发电,饲料,产沼气,肥料,燃料,建筑材料等。其中草砖作为一种以秸秆为原料用于建筑的围护承重的建筑材料具有其它材料无法比拟的优势。例如,利用秸秆草砖替代浪费土地资源和能耗较高的传统砖,每块草砖可替代82块粘土实心砖[3]。草砖建筑的优点有,建设成本低,能源效率高,保温性能好,提高屋内空气品质,调节草砖房室内温度,能保持较好的适合健康居住的空气品质.阐述了秸秆草砖建筑的结构体系,包括承重墙体和非承重墙体,以及他们的受力性能。介绍了抵抗水平力的系杆和秸秆砖的互连、秸秆砖与支撑结构的连接。并分析了草砖墙体的破坏模式。测算了冷弯薄壁型钢的承载能力。主要阐述了冷弯薄壁型钢组合结构的模型,利用有限元软件进行模拟。对结果的理论分析以及材料的属性的分析.秸秆草砖可以大大提高冷弯薄壁型钢墙体的稳定性,提高墙体的承载力,也可以减小局部的屈曲。以安图县一示范建筑作为研究对象,介绍了冷弯薄壁型钢-秸秆草砖组合结构的施工方法以及钢梁、钢柱、楼盖、墙体、楼板、支撑、等构件。并对组合墙体进行有限元分析,分析结果表明草砖作为一种柔性材料可以有效提高结构的整体稳定性,并可承担一定的荷载。
[Abstract]:Straw is used in many ways, including papermaking, burning electricity, feed, biogas, fertilizer, fuel, building materials and so on. Straw brick, as a kind of building material with straw as raw material, has unparalleled advantages over other materials. For example, straw straw brick is used to replace the traditional brick, which wastes land resources and consumes more energy, and each straw brick can replace 82 solid clay bricks [3]. The advantages of straw brick building are low construction cost, high energy efficiency, good thermal insulation performance, improving indoor air quality, regulating indoor temperature of grass brick house, and keeping good air quality suitable for healthy living. The structure system of straw brick building, including load-bearing wall and non-load-bearing wall, and their mechanical properties are expounded. The interconnection of tie bar and straw brick to resist horizontal force and the connection between straw brick and supporting structure are introduced. The failure mode of straw brick wall is analyzed. The bearing capacity of cold-formed thin-walled steel is calculated. The model of cold-formed thin-walled steel composite structure is described and simulated by finite element software. The theoretical analysis of the results and the analysis of the properties of the materials. Straw brick can greatly improve the stability of cold-formed thin-walled steel wall, increase the bearing capacity of the wall, but also reduce the local buckling. Taking a demonstration building in Antu County as the research object, this paper introduces the construction method of cold-formed thin-walled steel-straw brick composite structure and its components, such as steel beam, steel column, floor, wall, floor, support and so on. The finite element analysis of the composite wall shows that the straw brick as a flexible material can effectively improve the overall stability of the structure and can bear certain loads.
