中文摘要:
      为研究新型钢管脚手架外挂防护体系的破坏形式和极限承载力,为高层及超高层建筑施工钢管脚手架安全合理设计提供依据。依据风荷载作用计算公式,结合工程实例,对新型钢管脚手架外挂防护体系进行现场试验,并利用通用有限元软件ANSYS对单片外挂网进行数值分析。结果表明:有限元得到的极限承载力接近试验值,破坏形式与试验的相一致,相互之间得到了很好的验证;在风荷载作用下,新型钢管脚手架外挂防护体系能够承受的最大风荷载为3.25kN;外挂防护体系最薄弱的环节是卡座,变形最大的部位是外挂网斜撑交叉处。可见为了使两者更好的协同工作,在进行设计时,对卡座要进行着重考虑。
英文摘要:
      In order to study the damage form and ultimate bearing capacity of the new steel tube scaffold external protection system, and provide basis for safe and reasonable design of steel tube scaffold for high-rise and super high-rise building construction. The method was based on the calculation formula of wind loads and engineering examples. Field tests were carried out on the protective system of steel tube scaffold external hanging, and the numerical analysis of single-chip external hanging net was carried out by using the general finite element software ANSYS. The results show that the ultimate bearing capacity obtained by finite element method is close to the test value, and the failure mode is consistent with the test, which is well verified. Under wind load, the maximum wind load that the new steel tube scaffold external protection system can bear is 3.25 kN. The weakest link of the external protection system is the clamping seat, and the most deformed part is the intersection of the external net brace. It can be seen that in order to make the two work together better, the booth should be considered when designing.
