| Abstract: | The reinforced concrete core wall-steel frame hybrid structure is a non-proportional damping system. In practical structural designs, equivalent damping ratio is used and specified in the Technical Specification for Concrete Structures of Tall Building JGJ3-2002 of China. In this paper, a reinforced concrete core wall-steel frame hybrid structure under frequently-occur earthquake is calculated by using time history method in elastic range, with the non-proportional damping model and the equivalent damping model, respectively. It is found that there are great differences between the displacement and inner force responses by the two damping models. Some suggestions for using equivalent damping ratio of the structures is put forward. | |
