Dynamic Response of Reinforced Concrete Buildings with Coupled Beams

Abstract

Resistance of a building against seismic forces is one of the practical design parameters that considered while designing as well as during construction. In addition to the parameters, structural ponding is also a problem that occurs when the buildings are spaced closely during the earthquake. However, the functionality and objective of these buildings are different, which translates into different dynamic systems. Many techniques have been introducing and developing to design the structures safe. Coupling and bracing are some of the methods which hold the building together and act as a single inverted pendulum during the earthquake. In the present study, a horizontally coupled building system of 20 storey’s is developed separately with coupled beams and bracing systems. It is assumed that the two adjacent buildings were similar in this coupled building system, so the two adjacent stories could be coupled at the same height by an inter-building. And coupling with beams is introduced at different storey’s in the building, and results reveal that the building coupled beam at all storey showed the performance of the building in terms of displacement, storey drift, and storey shear.
