Abstract:The performance-based analysis and research were carried out for a high-rise out-of-code shear wall structure with top indentation and bottom staggered floors. Firstly, the strengthening measures for the tottom staggered and top indentation floors were put forward. Then, a comparative model was established for the top indentation floor to study the influence of the indentation floor on the structural stiffness and load-carrying capacity, and the performance-based analysis and dynamic elastoplastic damage analysis were carried out under the actions of fortification and rare earthquakes. The results show that the structural strengthening measures adopted  can basically meet the set performance objectives, ensure the reliability of the vertical irregular structure, and serious damage occurs to individual components in the tottom staggered and top indentation floors of the structure. Targeted strengthening measures should be taken in the construction drawing design stage.

Keywords:out-of-code high-rise building; shear wall structure; top indentation floor; bottom staggered floor
