Two weakness floors near the equipment floor are formed under the earthquake. The characteristics of the structure are analyzed. In order to prevent the weakness floor destroy seriously under rare earthquake, some measures are used, such as adjusting the location of shear walls and the section of members. The structure analysis results show that the deformation and bearing capacity satisfy the demands of the code. Based on the engineering design, the anti-seismic conceptual design method of frame shear-wall structure with double-weakness floor is given. The main technical measures can be referred in similar engineering.Keywords:frame shear-wall structure; double-weakness floor; detail measure; conceptual design
