| 摘 要： | 矩形钢管柱属于非劲性钢结构,在超高矩形薄壁钢管内浇筑混凝土极易引起变形.通过理论力学和有限元方法计算浇筑过程产生的变形值,论述在超高矩形钢管柱中浇筑混凝土采用螺栓外加固的变形控制措施和监测方法.竣工后的工程不仅节约了钢材,而且外观美观、牢固可靠.并通过施工分析现阶段设计和标准存在的问题.

| Abstract: | The rectangular steel-pipe column belongs to the non-stiffness steel structure,and the deformation can easily occur when depositing concrete in the tall rectangle thin wall steel pipe.Through the theoretical mechanics and the finite-element method it is computed the distortion value produced in construction process.It is also described the distortion-controling measures with bolt reinforcing and the monitoring method during the depositing concrete in the tall rectangle steel-pipe column.The completed projec... |
