摘要
某宾馆因功能改变,扩大会议室使用空间,需拆除2根中柱。为满足抗震和结构安全的需要,采用预应力技术、化学植筋技术、碳纤维加固技术、粘钢加固技术及扩大截面等手段对原结构进行加固处理后,安全拆除了柱。
Two columns in the middle of a hotel will be cut because of the change of fimction. To satisfy the safety of structure and seismic behavior, engineers take some strengthening methods, such as prestress technology, chemically-planted steel bar, CFRP strengthening, sticking steel strengthening and extending area. Finally, engineers succeed in solving this problem.
