近十几年来,我国钢产量有了迅速地提高。发展一种经济、实用、美观的轻型钢结构住宅符合我国社会发展的要求,对提高我国建筑技术水平和人民生活水平有着重要的意义。轻钢交错桁架结构正是适应这种需要的一种工厂化、标准化的新型结构体系,故而研究这种结构体系的受力性能和设计方法具有重要和深远的意义。
In the past ten years, China’s steel production has rapidly increased. The development of an economical, practical and aesthetically pleasing light steel structure house meets the requirements of our country’s social development and is of great significance to improving the level of China’s building technology and people’s living standards. The light steel staggered truss structure is just a kind of industrialization and standardization new structural system which adapts to this kind of needs. Therefore, it is of great and far-reaching significance to study the mechanical properties and design methods of this kind of structural system.
