空间网架是建筑上一种先进的新型结构,十几年来由于电子计算的发展,提高了对网架的分析计算能力,如对高次超静定结构的应力分析提供了可能性。使网架结构得到了广泛应用。我国首先在首都体育馆比赛大厅工程上采用,赶上和超过世界同类型最大屋顶的跨度,体现了我国工程结构有了新的发展。 Space grids are an advanced new type of structure for buildings. Over the past decade or so, due to the development of electronic calculations, the ability to analyze and calculate grids has been increased. This has provided possibilities for stress analysis of high-order statically indeterminate structures. The grid structure has been widely used. China first adopted the project in the competition hall of the Capital Stadium to catch up with and surpass the span of the world’s largest roof, reflecting the new development of our country’s engineering structure.
