Assessment of Redundancy Factors for the Seismic Design for Building Structures

Assessment of Redundancy Factors for the Seismic Design for Building Structures

In recent years, the investigation results of the earthquake damage that occurred due to the 2016 Meinong and 2018 Hualien earthquakes has shown that mid-to-high-rise buildings with only one-to-two spans in the direction of the earthquake are prone to significant earthquake damage. However, in the current Taiwanese building seismic code, the impact of structural redundancy on the seismic performance of a building is not considered. This study reports the design requirements of American and Mexican building codes for redundancy and proposes a design plan for structural redundancy that is suitable for the characteristics of buildings in Taiwan for the purpose of safely engineering such buildings.
