INVESTIGATION OF STEEL SLIT PANEL EFFECT ON MODAL PARAMETERS OF REINFORCED CONCRETE STRUCTURE BY FINITE ELEMENT METHOD

Abstract

The destructive effects of seismic loads on structures are known. Earthquake engineers have taken many precautions in their building designs to protect and minimize these destructive effects. In this way, many new design and reinforcement methods have been developed against seismic loads. The use of a steel slit panel (SSP) is one of the developed methods. Therefore, in this study, the effects of SSP on dynamic performance in a 5-storey reinforced concrete building model were investigated. For this, two models with and without SSP were created by the finite element method and modal parameters were compared. As a result of the data obtained, it has been observed that the building model makes more balanced displacements, as can be understood from the mode shapes. In addition, the SSP model made the structure more rigid by reducing the periods of the structure. It can be used in SSP prestressed reinforced concrete structures.
