Comparison of Damage Indexes in Performance Assessment of Special Concrete Moment Resisting Frames

The earthquake is one of the natural disasters that caused the many death. 10,000 people die annually due to earthquake around the world, and this incident has so far caused a lot of economic damages. In the structures review, earthquake damages can be classified into three categories: physical, soc...
