矗立于浦东陆家嘴金融贸易区中心的上海环球金融中心,是当今建筑屋顶高度和人可到达高度均创世界第一的高楼,屋顶高度达492m,超过了目前屋顶高度世界第一的中国台北101大厦(480m);在上海环球金融中心钢结构项目中,尤以三角形核心筒柱(以下简称三角柱)的焊接难度最大。本文介绍三角柱在焊接过程中如何保证焊接质量和有效控制焊接变形。
The Shanghai World Financial Center stands in the center of Pudong Lujiazui Finance and Trade Zone. It is the highest building in the world today with rooftop height and human reachable height. The roof height reaches 492m, surpassing the current peak roof height of China Taipei 101 (480m). In the steel structure project of Shanghai World Financial Center, the triangle core column (hereinafter referred to as triangle column) is the most difficult to weld.
