Abstract

The horizontal load greatly affects the horizontal displacement of the top of the reinforced concrete frame, especially for the frame with small stiffness. In high-rise buildings, it is necessary to check whether the horizontal displacement of the top of the building and the story drift is satisfied or not. This paper introduces the investigation of the influence of lateral loads on the horizontal displacement of the top of the reinforced concrete flat frame with regard to material nonlinearities using Lira-Sapr software. Therefrom, comment on the difference between the analysis of reinforced concrete frames with regard to material nonlinearity with the analysis according to the elastic.
