新型装配式临时作业棚结构开发与有限元分析
|
摘要
目的改进施工现场不可重复利用、不标准化的临时作业棚.开发一种可工厂预制,现场拼装、安装及拆卸简易、可重复使用且整体安全的新型装配式临时作业棚.方法针对沈阳地区的雪荷载和风荷载对新型装配式临时作业棚结构各构件截面及连接节点进行设计,并通过有限元分析软件ABAQUS对新型装配式临时作业棚整体结构施加雪荷载和两个方向的风荷载进行分析.结果新型装配式临时作业棚在雪荷载作用下,最大位移为13.85 mm,出现在上层檩条;最大应力为108 MPa,出现在横向框架.在两个方向的风荷载作用下,最大应力分别出现在斜撑与柱底处,分别为153 MPa与121.6 MPa;最大位移均出现在上部防护结构,分别为58.47 mm与25.21 mm.结论设计的新型装配式临时作业棚在正常使用中满足《钢结构设计标准》(GB50017—2017)与《门式刚架轻型房屋钢结构技术规范》(GB51022—2015)中对钢结构强度与刚度设计要求,具有良好的受力性能,可以应用于实际工程中.
A new prefabricated temporary work shed was developed by improving its shortages in construction site,such as non-reusability and non-standardization,which can be prefabricated in factory and assembled in site,installed and disassembled simply,reused and safely.Considering the snow and wind load in Shenyang,the section and joint of the new prefabricated temporary work shed were designed,and the snow and wind load are applied to the structure of the new prefabricated temporary work shed by the finite element analysis software ABAQUS.The results showed that under snow load,the maximum displacement of new prefabricated temporary work shed is 13.85 mm,which appears on upper purlin;the maximum stress appears on the transverse frame,which is 108 MPa.Under wind load in two directions,the maximum displacements both appear on upper safeguard structure,the displacements are 58.47 mm and 25.21 mm,respectively;the maximum stress appear on diagonal brace and columns base,which are 153 MPa and 121.6 MPa,respectively.The New prefabricated temporary work shed not only meets the requirements of strength and stiffness design in Standard for design of steel structure(GB50017—2017)and Technical code for steel structure of light-weight building with gabled frames(GB51022—2015)in normal use,with good mechanical performance.The New prefabricated temporary work shed can be applied in practical projects.
