Evaluation of structural systems in slender high-rise buildings

Abstract

With the rapid population growth and scarcity of developable space, especially in large cities, there is a need for increased density in both commercial and residential housing, and hence a strong demand to maximise floor space by constructing not only tall, but also slender buildings. This study considers different structural systems available for constructing slender high-rise buildings and evaluates their feasibility in terms of the lateral deformation being one of the key governing design criteria for very tall buildings. To examine the performance of different structural systems in buildings of varying height and floorplan, this study applies finite element analyses in a parametric study to compare nine different building configurations under static loading with heights varying from 80m to 460m. The study shows that buildings with square footprints can achieve greater heights over rectangular footprints with the same area and that multiple towers when connected structurally at one or more levels can achieve even greater heights.

Effects of dynamic soil-structure interaction on seismic behaviour of high-rise buildings

“…However, the seismic response of low-rise and high-rise structures are different. In the same way, the seismic response of frame structures is different from that of the frame-shear wall structures in which foundation rotation is significant (Sharma et al 2018;Walsh 2018). Therefore, it is imperative to investigate the behaviour of high-rise wall-frame buildings with different superstructure geometry considering SSI.…”

Shear Capacity Analysis of Welded Steel I-Girders with Corrugated Webs based on First Yield

“…Since CWBs are actively used in different design fields, some essential properties including post-buckling strength, deflections, and shear capacities of corrugated-web beams need to be investigated. Beams are the significant components to support floors and the loads will be transmitted to the foundation by the beam-column connections (Ingkiriwang & Far 2018;Walsh et al 2018;Haydar et al 2018, Far 2019. Therefore, different aspects of strength of structural beams or girders should be clearly determined to eliminate the potential failure of the structures.…”
