| Abstract | The present research aims to experimentally verify the reduction of soft-story effect in buildings using RC infill wall which is based on numerical optimization.Buildings which are often used for parking, commercial spaces, or business open areas, might be left open on the ground floor, could have one of the vertical irregularities which is called soft-story effect. This soft-story effect becomes a significant concern during earthquakes because it can lead to disproportionate structural damage and potential collapse. The soft-story floors may undergo excessive lateral displacement and deformation due to their reduced stiffness.Seismic retrofitting can be highly effective in reducing the vulnerability of buildings in high seismic areas. Retrofitting involves making structural enhancements to existing buildings to improve their ability to withstand the forces generated by earthquakes. Retrofitting solutions for developing countries should be implementable and meet usability, local availability without too much complexity. The global and local performance after retrofitting should also be better. The retrofitting cost should also be within the affordable range for the local people. Numerical Optimization is used to get the solution which fits all these requirements. This research is to experimentally verify the retrofitting solution which is based on numerical optimization and already accepted theoretically.Experiments in structural engineering bridge the gap between theoretical models and real-world behavior, leading to safer, more efficient buildings for people. This research hopes to fill the gap between the experimental and theoretical validation of the optimized RC infill wall retrofitting solution according to local accessibility, cost, performance, usability and complexity for buildings. |
