Performance based Seismic Evaluation of a Residential Reinforced Concrete Frame Building Using Nonlinear Static Analysis and Fast Nonlinear Analysis

Abstract

In this paper, a performance-based seismic evaluation of a residential reinforced concrete frame building located in Italy which was designed only for gravity loads is performed using Nonlinear Static Analysis and Fast Nonlinear Analysis (FNA). This building within the current study is subjected to three moderate earthquakes that occurred in Italy with a close magnitude level and different types of faults, two of them are aftershock earthquakes. The current investigation has shown that the Fast Nonlinear Analysis has given more critical values for performance-based seismic evaluation, which is expected. However, the used earthquakes have different effects on the structure, where the non-aftershock primary earthquake has given a more critical behavior for the building in both directions. This confirms the necessity of selecting earthquakes methodically depending on site geology, mechanisms of faults formed, and other conditions as codes and researches refer.
