Overview of Seismic Retrofitting of Existing Stadiums

Existing stadiums with low seismic fortification criterion can not satisfy the requirements of current seismic design code.Seismic evaluation and strengthening of stadiums built before 1990s are of great significance to enhance urban seismic regional planning and promote seismic shelter constructions.Reconstruction study of stadiums of different stages in different countries was introduced in this paper.Key retrofit techniques and factors needed to be considered in stadiums retrofitting were also summarized.As shelters after earthquake, the aim of stadiums retrofitting is to ensure life safety and the main methods are increasing resistance or dissipating energy.
