Abstract

Non-linear static analysis serves as a suitable measure to evaluate the performance of a structural system. The careful selection of the load pattern is critical to arrive at an adequate performance evaluation. These force distributions do not represent the exact effects of varying dynamic characteristics during the inelastic response or the influence of higher modes. Hence, meticulous consideration must be given in choosing a certain load pattern. The present analysis seeks to evaluate and compare the response of an eight-story reinforced concrete structure by applying load patterns prescribed by several guidelines using Etabs 18.1.1. The results indicate with acute clarity that, in all cases, the shape of the lateral load distribution is what the response of the building is finely accustomed to. This is especially true when different patterns of load are considered and analyzed. The first mode is found to be predominant, and higher modes are negligible.
