Performance of High Rise Structure with Lead Rubber Base as an Isolation System

A weak story, often referred to as a soft story, is one that has insufficient ductility to withstand the forces placed on the building by an earthquake. Buildings with soft stories typically have a story with a lot of open space. Since soft stories are traditionally associated with retail establishments and parking garages, they are frequently located on the lower stories of a building. As a result, when they collapse, they have the potential to bring the entire structure down, resulting in severe structural damage that may render the building completely unusable. However, there have only been a few studies on the impact of soft storeys at various levels in tall structures. This study will therefore investigate the impact of soft storey level variation in 45 storey building with and without LRB isolated structures.
