江苏大剧院大跨钢结构施工健康监测技术

摘要

江苏大剧院钢结构工程包括歌剧厅、音乐厅、戏剧厅、综艺厅4个单体钢结构工程.外罩钢结构形式类似,均由斜柱、摇摆柱、中环梁、顶环梁以及内凹顶盖的钢拉梁与环梁等主要部分组成.屋盖跨度大、结构受力复杂,为验证钢结构施工方案的合理性,确保钢结构施工过程中结构的安全性,对钢结构进行变形和应力、应变监测,监测结果可作为结构安全与否的重要评估指标.%The steel structure engineering of Jiangsu Grand Theatre includes opera hall,concert hall,drama hall and arts hall of four monomer steel structure engineerings.The housing steel structures are similar,consisting of inclined column,swinging columns and ring beam,top ring beam and the concave top steel beam ring beam and other major parts.The roof span is large and the structure is complicated.In order to verify the rationality of the steel structure construction scheme and ensure the safety of the structure during the construction of steel structure,the deformation,stress and strain monitoring of the steel structure are conducted,which can be used as an important evaluation index for the structural safety.
