[摘要]：某酒店为满足建筑功能的需要，计划对原七层的混凝土框架结构建筑进行加层改造，增加两层钢结构。由于加层后结构整体的刚度、周期、质量等均有较大变化，故需要对结构进行整体性分析。本文通过对加层前后结构受力性能的对比分析，以及结构的构件配筋和整体变形的验算，论证该工程加层方案的合理性，并提出可行的加固处理方案。

Abstract：In order to satisfy the construction function,a hotel,which is a seven-story concrete framed structure,is planed storey-adding transformation by increasing two layer steel structure.Because there is comparatively big change in entirety stiffness、period and mass after storey-adding transformation,it is needed to analyse integrity of the structure.By the comparative analysis in the force function of original structure and storey-adding transformation structure,and the check in Component reinforcement and entirety deformation.the book is demonstrated the rationality of the storey-adding transformation and proposed feasible reinforcement program.
