【摘要】 针对装配式混凝土结构的施工,提出一种在附着层添加钢柱,钢柱与楼板通过抗剪件和螺杆进行连接,塔机附着在钢柱上的塔式起重机附着方案。采用有限元法对该附着方案进行非线性有限元分析,并以某实际工程中的1根附着钢柱作为监测对象,测试极端受力条件下的受力状态,结果表明钢柱处于弹性状态且有较大的安全储备,该附着方案可行。更多还原

【Abstract】 Aiming at the construction of prefabricated concrete structure,an attachment system of tower crane was presented in this paper,in which the tower crane was attached to a steel column,and the steel column was connected to floor plate using shear connector and screw arbor.Nonlinear finite element analysis for this attachment scheme was carried out,and an attached steel column in a real project under extreme stress state was monitored.The results show that the steel column is in elastic state and has larger safety reserves.The presented attachment scheme is feasible.更多还原
