Nowadays, use of curvilinear architecture in tall buildings design is becoming increasingly important, so as structural engineers, we need to study these curved configurations from a structural point of view.
This paper summarizes the results of a performance-based assessment of buildings with curved shear walls.
The assessment was carried out using nonlinear static pushover analysis of Four (G+10 Typ.
) concrete buildings which were divided into two categories.
Each category included two buildings.
The main parameter was the shape of the shear wall in plan and all the other parameters as the reinforcement ratio, the concrete volume, and position of shear walls were the same.
A comparison was made between different plans with straight and curved shear walls.
First, a modal analysis was carried out to determine the building's dynamic characteristics.
Then an ASCE7-16-based [1] equivalent static procedure was performed to approach a fair design data based on ACI318-14 Code [2] and to determine the design base shear required by the ASCE7-16 [1].
After that the four buildings were subjected to a monotonic pushover loading in triangular vertical pattern using software PERFORM 3D [3].
The response modification factor, R, was then calculated based on the displacement ductility and the overstrength of the different buildings.
The results of the analysis have shown that buildings with curved shear walls have larger response modification factor and are more energy dissipating than buildings with straight shear walls.
