【摘要】 为助力国家“双碳”目标的实现，促进我国城镇民居的节能减排，提出了一种竹缠绕装配式建筑。该建筑的结构体系是钢结构框架，在现场将工厂预制好的竹缠绕筒体作为房屋单元通过螺栓实现与钢结构框架的连接。由于竹缠绕筒体的底板作为楼板，代替传统装配式钢结构中的钢筋桁架楼承板，结构的整体刚度较弱。基于某一试点工程，采用YJK软件对该结构进行小震作用下的反应谱计算和时程分析，结果表明主体结构和连接构件安全可靠。采用ABAQUS软件对竹缠绕房屋单元进行了使用荷载和重力荷载作用下的有限元计算，结果表明竹缠绕房屋单元的强度和变形满足要求。基于以上有限元计算方法，给出不同房屋单元尺寸所需要的最小壁厚供设计人员参考。更多还原

【Abstract】 To help achieve the "dual carbon" target and promote energy conservation and emission reduction in urban residential areas, a bamboo winding prefabricated building was proposed. The building is a steel frame. The prefabricated bamboo winding cylinder is used as a housing unit to connect with the steel frame through bolts on site. Due to the fact that the bottom plate of the bamboo winding cylinder serves as floor, replacing the steel truss floor deck in traditional prefabricated steel structures, the overall stiffness of the structure is relatively weak. Based on a pilot project, using YJK software to perform response spectrum and time his-tory analysis of the structure under frequent earthquakes. The results show that the structure and connecting components are reliable. ABAQUS software was used to perform finite element analysis on bamboo winding cylinder under service load and gravity. The results show that strength and deformation of bamboo winding cylinder meets the requirements. Based on the above finite element method, providing the minimum wall thick-ness required for house units of different size for designers to use.更多还原
