摘要

研究目的:劲性支撑弯顶结构是一种新型的预应力空间结构,克服了索弯顶结构的许多施工技术难题。该结构具有节点定位容易、结构效率高及自支撑自平衡等特点。从工程应用的角度,结合劲性支撑弯顶结构的自身特点,本文提出了一种施工安装张拉方法,并给出了模拟分析策略及程序实现方法。
研究结论:(1).提出逐节点拼装整体张拉提升的施工安装张拉方法,给出了施工控制和监测方法;(2)采用改进的动力松弛法对施工过程进行模拟分析,给出实现策略,采用FORTRAN和ANSYS的APDL语言编制程序;(3)算例分析表明,提出的施工安装方法可以有效减小结构构件在施工张拉过程中的超张拉问题;(4)研究成果为劲性支撑弯顶结构的工程实践提供施工和分析方法等方面的参考。

Abstract

Research purposes: Rigid bracing domes are a new type of prestressed spatial structures,many construction technology challenges of cable domes are overcome by it. The structure has characteristics of easy node location, high efficiency,the support from the balance and so on. According to characteristics of rigid bracing dome,the construction method was proposed from the engineering view,and then simulation analysis strategies and procedures for implementation were given.
Research conclusions:(1)The method is that rods are installed in accordance with the order of nodes and then the system are enhanced the overall and tensioned. Construction control and monitoring methods were given.(2)The construction process was simulated by the improved dynamic relaxation method. Implementation strategy was given. Program was programmed by using FORTRAN language and ANSYS APDL language.(3)Numerical example shows that super-tensioned problem can be effectively reduced through the proposed construction and installation methods. (4) References to the construction and analysis are provided by the results for practical engineering of rigid bracing dome.
