【摘要】 对大跨度超大空间体育场馆抗震体系设计提出新的布局和思路,成功地将型钢混凝土框架-钢支撑体系运用到国家体育馆的抗震设计中,对这种新型结构布局产生的问题和特点进行分析。由于钢支撑的斜向交接,更增加了型钢梁柱节点的复杂性,对新型平面三向交叉变截面节点建立力学模型并对其力学特征予以探讨。对复杂型钢节点及截面的开孔影响进行比较和分析,解决型钢与钢筋的结合问题。更多还原

【Abstract】 New layout and method are presented for the design of seismic system of large-span super space gymnasium. The shape steel concrete and steel brace system is used in the seismic design of National Gymnasiums, and problems and characters of this kind of structure are analyzed. Mechanics model is established for three-direction intersect plane joint, and the mechnics character of the joint is discussed. The effect of complex steel joint and hole in section is compared and analyzed.更多还原
