Studying the Effect of Wind Loads on a 16 Story RC Building Using Nonlinear Static Analysis (Dual System)

Abstract

This research aims to evaluate wind effect on high-rise RC-buildings using nonlinear static analysis, and to compare performance objectives with acceptance criteria, with the aim of improving their structural design resulted under severe wind loads.

A model of a 16-storey RC Dual System (Frame-Shear Wall) building was studied. Designed according to the Syrian Arab Code and its Appendixes, to evaluate the nonlinear structural response under the influence of wind loads.

The 3D model was created and analyzed using finite element software (ETABS 2018), taking into account the nonlinear behavior of the concrete and rebar and the geometric nonlinearity through P-Δ effects.

Results shows that Demand/Capacity Ratio (DCR) values for some structural frame elements (columns and beams) have exceeded the acceptance criteria limits. In this paper structural modifications were made to achieve required response.
