Earthquake Effect on a 10-Storey RC Building

Abstract

Earthquakes are natural phenomenon that occurs around the world. They can cause severe damage to the buildings, the environment, and, most importantly, to the people. Thus, the need for seismic-resistant structures is really important to reduce the damage caused by seismic events.

Reinforced concrete structures have been used as seismic-resistant structures and have proved their efficiency in decreasing earthquake damage. Especially the structures that have shear walls. In this paper, five FEM models are made using Axisvm according to Eurocode8; four of the models have shear walls, and one does not. The shear walls are placed symmetrically, and their position is different in each of the four models.

The five models are designed for Ductility Class Medium (DCM), and this type of design is for areas with moderate seismic activity. Then, vibration and linear analysis were conducted for all the models and the results were compared between them.

From the vibration and linear analysis, the results for the displacement, inter-storey drift, and the period of vibration were compared and analyzed. It was concluded that the models that had a certain configuration of shear walls showed better and safer results than the other models. However, the shear force has increased in the models that had shear walls.
