张弦梁是一种新型的结构体系,近年来常用于大型的展览和体育建筑中。在张弦梁结构中,张拉索虽然材料量和工程量都不大,却对整个结构起到了至关重要的作用。在张拉过程中,结构各部分的内力都在不断的改变,影响这种改变的因素也很多,因此张弦梁的施工是一个动态的变化过程。通过有限元模拟施工过程,可以对张弦梁及其它结构之间的相互作用有了充分的了解,确定了施工特别是张弦梁张拉的有关条件和参数,并且通过计算了解各个施工工况中结构内力的变化过程,以科学的分析来指导屋面的安装施工及整体张拉工作。
Zhang Xianliang is a new type of structural system, which is commonly used in large exhibitions and sports buildings in recent years. In the string beam structure, the tension cable although the amount of material and engineering are not large, but the entire structure has played a crucial role. In the process of tensioning, the internal forces of various parts of the structure are constantly changing, and there are many factors that affect this change. Therefore, the construction of the beam string beam is a dynamic process of change. Through the finite element simulation of the construction process, the interaction between the beam string and other structures can be fully understood, and the relevant conditions and parameters for the tensioning of the construction beam, especially the beam string beam, have been determined. The internal forces of the beam in various construction conditions The process of change, scientific analysis to guide the installation and construction of the roof and the overall tensioning work.
