THE INFLUENCE OF DILATATION ON REINFORCED CONCRETE STRUCTURES WITH U-SHAPED FLOOR PLAN DUE TO EARTHQUAKE LOADS

Abstract

Earthquakes are defined as vibrations originating from the movement of tectonic plates beneath the earth's surface, with the greatest impact on building damage, especially high-rise asymmetrical buildings that have a high potential for horizontal displacement in the building structure. For this reason, it can generally be overcome by using dilatation in order to reduce building irregularities. In this analysis process, the building model is divided into 5 structural models, namely a model without dilatation (intact with a U plan), with two column dilatation divided into 2 parts called buildings A, and B, and cantilever dilatation divided into 2 parts called buildings A and B. All models are designed with a truss system. All models are designed with a special truss system. From the results of the structural analysis, it is found that the dilatation greatly affects the deviation between floors, the structural vibration period and the p-delta that occurs in the building. The internal forces that occur in columns and beams also show significant results, especially in columns with structures without dilation compared to using dilation.
