Abstract

Recently, a visco-elastic damper (VED) has been applied to multistory buildings to reduce the responses of structures under strong earthquakes. However, there is few study for the application of the VEDs to space frame structures. The purpose of this study is to show the effectiveness of the VEDs installed in a gable truss structure under severe earthquakes. Earthquake response analyses are carried out with varied parameters;(1) the position of the VEDs, (2) the size of the VEDs, (3) the magnitude of peak acceleration of earthquakes. The results based on the numerical studies have confirmed that the VEDs effectively suppress the earthquake responses of the gabled truss structures.
