Abstract:The analysis of the application range, mechanical behaviour and economic benefit of the diagonal grid-beam structure was carried out according to several project cases. The results show that this structure have better structural performance and economic benefit, and is suitable to rectangle whose length-width ratio is more than 1-5 or oval plane structures. Besides, it can make full use of the framework columns to form the better structural rigidity which performed well in ductility and bearing capacity.

Keywords:diagonal grid-beam structure; structural efficiency; project example
