大跨度落地格构式框架结构的设计探讨

THE DESIGN OF FLOOR TYPE LONG-SPAN LATTICE FRAME

大跨度落地格构式框架结构是结合门式刚架结构和拱式桁架结构的受力优点而衍生的一种大跨度结构形式。对该结构体系的结构特点、布置原则、计算控制要点进行探讨。并结合工程实例,论证该大跨度结构体系不仅受力性能、抗震性能良好,而且技术经济指标优良,值得推广。

Floor type long span lattice frame is a derived long span structure combining portal frame with arch truss.This paper mainly focuses on structural features, arrangement and computing control.It is worth spreading since it demonstrates the structure is good both in stress and earthquake-resistant performance,moreover,the technical and economic target is excellent too.
