建筑物整体移位托换体系的计算机模拟
|
摘要
结合历史保护性建筑——上海音乐厅整体移位工程,建立了建筑物整体移位托换体系模拟计算模型。通过对建筑物整体移位工程——上海音乐厅钢筋混凝土托换体系材料参数输入试验值,对经该音乐厅柱子传递到托换体系的上部结构荷载视为集中荷载,对用于顶升该音乐厅的千斤顶分别按于设计分布位置集中受力,采用三维结构计算程序进行模拟计算,预测出建筑物整体移位托换体系的变形及用于顶升该建筑物的千斤顶的受力状况,计算结果与实际较一致,为指导该工程信息化施工做出了较大的贡献。研究成果表明,建立的研究建筑物整体移位托换体系的安全、可靠性方法科学,模拟计算结果可靠。
This paper established a calculation model of Shanghai Concert Hall integer shift's underpinned system,combined with the historic and protective architectural shift project. It considered the structural load of the Hall's upper part as the concentrating ones to deliver through its pillars,and regarded the lift system's jacks as focus loads at the design sites. It finished the simulating calculation by inputting the trial values of material parameters about the Hall's reinforced concrete underpinned system and using three-dimensional structural simulation procedure. The forecasting results are more consistent with the actual,which made a great deal of contribution guide the project's information construction. The study showed that it is safe about the underpinned system of Shanghai Concert Hall integer shift,and the method is scientific,and the calculation results are reliable.
