Ductility of the structural members and joints are usually adopted to dissipated the earthquake energy and to avoid the collapse failure of the whole structure. The design laterial force is also related to the characteristics of ductility of the structure. Since the structure with superior ductility can be designed by using smaller member size, theses structures may run into inelastic range under moderate earthquake or cause non- structural failure. Various types of damper have been found to be able to reduce the earthquake response effectively. Viscous elastic damper (VE damper) is one of the promising damper in solving these problems. VE damper has been used for the mitiga- tion of structure under wind excitation for quite a long period. However, the application of VE damper in the seismic resistant design is very limited. This reported study examined the behavior of steel frame with VE damer under strong ground excitation. A three stories modeled steel building with different design of damper was tested under various earthquake motion. Another bare frame (SMRF) was also tested as reference datum. The preliminary results shown that the frame with VE damper performs very good under small to moderate earthquake but not as good as was expected when it is under severe earthquake. It is suggested to consider the high amount of temperature rise if the structure is designed to resist strong earthquake.
