设计参数对施工过程中环形索桁结构的力学性能影响分析

RESEARCH ON MECHANICAL PROPERTY OF ANNULAR CABLE-TRUSS DURING SLING CABLE ERECTION PROCESS BASED ON DESIGN PARAMETERS

基于参数化的性能设计,进行了结构边界条件、拉索类型、索初始高度等参数的变化对吊索施工过程中结构力学性能的影响分析研究。结果表明:边界条件选取的不同对结构的力学性能有较大影响;拉索类型的选取对结构的受力也有一定的影响;吊索边界高度越高,结构受力越趋向合理,但也受建筑设计要求高度的限制。

In order to meet the thought parametric design, the impact on mechanical of integration of design and construction, based on properties of the structure was analyzed by different boundary conditions, cable types, and initial cable height. The results showed that： different boundary conditions on the mechanical properties of the structure have a greater impact; cable type selection has a certain influence on the structure; the higher altitude of lifting cable, the more mechanics of structure tend to be reasonable, but also restricted by architectural design requirements.
