The effect of retrofitting high-rise buildings with steel plate shear walls

Abstract

The construction of high-rise buildings carries the potential for collapse due to lateral loads, such as wind and earthquake forces. Therefore, the use of lateral force retaining systems need to consider in designing high-rise building. This research provides an overview of how the performance of a high-rise building with stiffened steel plate shear walls (SPSW) as a lateral force retaining systems. The study evaluates the impact of SPSW on a story drift and cross-section capacity of beams and columns high-rise building. The results indicate that SPSW systems enhances the seismic performance of high-rise building. Specifically, the use of SPSW with the thickness 18.7 mm has the most significant effect on the story drift and cross-section capability of columns. Using thicker steel plate shear walls can effectively decrease the story drift experienced in high-rise buildings. Based on the results, the story drift value is reduced by 3-6 mm with a structural system with SPSW. On the other hand, the cross-section capability of the column element is also improved. However, the increasing thickness of SPSW does not have a significant impact on the cross-section of the beam element.
