摘　　要：上海浦东足球场是国内外首个采用中置压环索承结构体系的足球场,将一般放置在柱顶的压力环向内移动到V形支撑上,形成空间的曲线的中置压环,解决了外置压环索承结构体系不能适应矩形建筑平面的问题。通过有效的找形分析,确定了内环和径向索的预应力,使压环在自重下几乎没有弯矩。通过物理风洞试验和数值风洞试验确定了结构的风荷载,并进行了双非线性整体稳定分析,分析结果表明安全系数满足规范要求。对径向梁进行了局部稳定分析,从考虑截面有效性和最大化利用钢材的角度来选择腹板壁厚。介绍了径向索与径向梁连接节点和索夹节点,以期为其他工程提供数据参考。在屋盖钢结构上布置健康监测系统,对其在施工和长期工作状态进行实时监测,结果表明,各个部位应力监测值与理论值相接近,位形与理论值基本相符,结构安全可靠。Shanghai Pudong Football Stadium is the first football stadium to innovatively adopt a cable-supported structure system with an intermediate compression ring in the world.The compression ring generally placed on the top of the column is moved inward to the V-shaped support to become a curved intermediate compression ring of space,which solves the problem that the outer compression ring cable-support structure cannot adapt to the rectangular building plane.Through effective form-finding analysis,the prestress of the inner ring and radial cable was determined,so that the compression ring has almost no bending moment under its weight.Physical wind tunnel tests and numerical wind tunnel tests were carried out to determine the wind load of the structure,and the double nonlinear overall stability analysis was carried out which analysis result indicates that the safety factor meets the requirements of the code.The local stability analysis of the radial beam was carried out,and the web wall thickness was selected by considering the section’s effectiveness and maximum utilization of steel.Connection nodes of radial cable and radial beam and cable clamp nodes were introduced in order to provide data reference for other projects.The health monitoring system was arranged on the steel structure of the roof to monitor its construction and long-term working state in real time.The results show that the stress monitoring value of each part is close to the theoretical value,the configuration is consistent with the theoretical value,and the structure is safe and reliable.
