摘 要: | 超高层建筑施工中,钢平台模架体系是混凝土施工的重要装备。在超高层建筑施工智能化液压顶升钢平台模架体系中对设计的单榀贝雷架进行实例分析发现,各杆件在不同等级荷载作用下呈现的内力值是有一定规律的。本文使用同济大学钢结构-空间结构设计软件3D3S进行模拟计算得到跨度21米、24米、27米、30米四种等级荷载作用下单榀贝雷架内力情况,并且总结出相同跨度的贝雷架在不同等级节点荷载作用下的内力规律,以及不同跨度的贝雷架在相同等级的节点荷载作用下的内力规律。

Abstract: | In the construction of super high-rise buildings,the steel platform formwork system is an important equipment for concrete construction.In the intelligent hydraulic jacking steel platform formwork system of super high-rise building construction,it is found that the internal force value of each member under different levels of load has a certain rule during the case analysis of the designed Bailey frame.In this paper,3D3S software is used to calculate the internal forces of a single Bailey frame with spans of 21 m,24 m,27 m and 30 m respectively.The internal force rules of the same span Bailey frame under different loads and different span Bailey frame under the same load are summarized. |
