摘要
首先介绍了广州科学中心幕墙支承索网的设计特点,并对这种新型的梁索杂交支承体系在索网张拉过程中的力学问题进行了剖析,然后提出了一种基于拟滑轮、虚拟温度荷载和生死单元技术的索网张拉迭代算法,并运用此算法对广州科学中心索网的张拉过程进行了精确模拟分析,为索网的设计和施工提供了重要依据。
At first the feature of cretin wall supporting cable nets in Guangzhou Science Center(GSC) was introduced. Then, many mechanical problems for this new hybridism support system was pointed out. Lastly, a kind of iteration algorithm, based on simulating block, virtual thermal load and element live and death technique, was presented and used to simulate the cable nets tension process. Some important references were given to the design and construction of GSC.
