Horizontal displacement at the top of the building with frame and shear walls structures according to TCVN 2737:2023

Abstract

When designing the structure of a high-rise building, it is important to consider not only the load-bearing capacity of the entire building but also the issue of limiting horizontal displacement at the top of the building. In this study, the author used Etabs software to analyze and compare the horizontal displacement at the top of a building. The study focused on two different types of structural system: frame system (consisting of columns, beams, and floors) and shear walls (which consists just of reinforced concrete walls). The analysis was conducted in accordance with Vietnamese standards on loads and impacts, specifically TCVN2737:2023. The wind loads were applied to the geometric center of the structure. Research results suggest the impact of horizontal displacement at the top of high-rise buildings is significant. Additionally, it has been observed that the shear walls system shows an increased horizontal displacement value compared to the frame system.
