摘要
尼日利亚New Minna体育馆屋盖采用空间管桁架结构,跨度为75.4×86.8m,主桁架在短方向。体育馆看台采用混凝土框架结构,建筑外皮为外倾6°的混凝土结构。本文主要介绍了该工程设计过程中一些主要设计参数(基本风压、抗震设防烈度等)的选取、主体结构及屋盖钢结构的具体结构设计。
Space tube truss was adopted for the steel roof of the Gymnasium in the New Minna Sport Complex, Nigeria, The span is 75.4×86.8m, the main truss is in the short direction. The stands is concrete frame, and building skin is a concrete structures with 6 degree inclination. How to chose the proper design parameters （the basic wind pressure, seismic fortification intensity etc）, and the structure design of the tube truss and concrete frame was introduced.
