张拉成形网格结构成形过程参数分析
|
摘要
为进一步掌握张拉成形网格结构成形性能,根据结构特点,以结构上弦截面、腹杆、刚臂、高跨比、中心环梁等为主要影响参数,通过理论模拟与分析,结合其现场施工方法,就一个100m跨的张拉成形网格结构工程实例,全面研究了各设计参数对结构成形性能的影响,结果表明,上弦截面、刚臂节间数和高跨比是影响结构成形的3个最主要的参数,其余参数对结构成形内力影响不大,适宜的刚臂对结构成形非常有利,并得出了各参数对结构成形的影响特点.
In order to catch on the forming performance of the stretch forming lattice structure(SFL),upper chord cross section、web member、rigid arm、high-span ratio,diameter and stiffness of center ring are selected as the main parameters affecting the forming process of SFL,which basing on the structural property.Taking practically tensioning method into consideration,a study of parameter effect on the forming process is carried out as far as an SFL with a long span of 100m is concerned by the theoretical simulating and analysis.The result shows that upper chord cross section、rigid arm number、high-span ratio are the most important factors affected the shaping process.The other parameters have little effect on forming process.It is favorable to the erection of SFL into its final configuration to choose reasonable stiffness of rigid arm.The structural properties about the forming process affected by the parameters are also given.
