摘　　要：上海世博会综艺大厅由老厂房改建而成。建筑设计中需要抽掉原厂房中间跨的一根钢柱,此钢柱为网架屋面的一个重要支承点。结构设计中主要采用"抽柱换梁"的方式对网架进行改造,并对施工过程、正常使用状态下引起的网架杆件内力重分布情况进行分析研究,采用管壁外粘结钢管的方法对网架局部杆件进行加固处理。Shanghai EXPO performance hall was reconstructed from the old plant.Architectural design needs to remove a steel column locating at the original plant center.This column is an important supporting point of the grid structure roof.The concept of replacing column with beam was applied in the rebuilding construction of grid structure roof in the structural design.The re-distribution of internal forces of grid bars was studied and analyzed respectively in the following two cases,construction process and normal use condition.Furthermore,a number of grid bars were strengthened using the method of bonding steel tubes outside the grid bars.
