【摘要】 首都速滑馆是11届亚运会期间兴建的体育馆中平面尺寸最大的一个。速滑馆的屋盖结构,是由60榀预应力(?)形刚架和梭形空间桁架组成的。本文介绍了这种组合式屋盖结构的设计、主要构造、静力和动力性能。动力分析结果表明,地震作用时,下部支承结构的惯性效应对此类屋盖结构的影响不容忽视。更多还原

【Abstract】 The Capical Speed Skating Gymnasium built during the XI Asian Games is the largest among all the gymnasiums built in China. It can provide 6 basketball courts, 4 volleyball courts and 2 handball courts to bo used at the same time. The roof structure is composed of 60 prestressed concrete (?) shaped rigid frames and shuttle-shaped space steel truses. In this paper the space truss-rigid frames’interaction as well as its static and dynamic performances, and their main details are presented. Dynamic analysis shows that the effect of the inertia of the lower-support structure on such roof structure should not be ignored in aseismic designs.更多还原
