某工业厂房二次改造结构加固设计与实践

The Design and Practice of Strengthening the Secondary Transformation Structure of an Industrial Workshop

某混凝土框架结构工业厂房建成于20世纪80年代末,2007年改造成快捷酒店使用至今,现将其再改造为办公楼,根据安全鉴定结果和建筑功能需要,经过系统的计算分析、全面复核,对局部桩基补强,对承载力不足框架柱加固,对较大范围楼板拆除再新建等有效措施,并考虑拆除与加固的施工次序,确保二次改造后的整体结构能满足现行规范要求。

A concrete frame structure industrial workshop was built in the late 1980s and transformed into a fast hotel in 2007.Now it is transformed into an office building.According to the results of safety appraisal and the needs of building functions,through systematic calculation,analysis and comprehensive review,some effective measures such as strengthening the local pile foundation,strengthening the frame column with insufficient bearing capacity,and removing and rebuilding the large-scale floor slab are considered Consider the construction sequence of demolition and reinforcement to ensure that the overall structure after the second transformation can meet the requirements of the current specifications.
