seismic performance evaluation of code-designed grandstand structure of a roofless sport stadium

Nowadays, special structures such as sports stadiums have become part of the megacity’s engineering symbols. given the significant investments made by the public or private sectors for construction and operation of these specific structures, it is essential to develop appropriate approaches for facilitating decision making in risk management of building financialsectors, especially in the seismic prone areas. currently, stadiums have considered in the category of buildings with high importance according to the iranian code of practice for seismic resistant design of buildings (2015). therefore, no major damages maybe expected for these buildings under the seismic hazard level of 10% probability of exceedance in 50 yearsand they can be repaired quickly for reusing during the design level earthquake events. however, the adequacy of simplified seismic code design procedures when applied to this type of buildings is questionable in terms of seismic performance byconsidering randomness and uncertainty in both the seismic loading and building resistance.
