ESTIMATION OF RESPONSE AND BEAM ENDS DAMAGE OF STEEL FRAME HIGH-RISE BUILDINGS UNDER LONG PERIOD MOTIONS

Abstract

Earthquake response analysis of 30 high-rise building models under long period motions is carried out. There are some cases in which the response exceeded the safety limit, when the level of input long period motion is larger. Damage to beam ends of high-rise building models is estimated. Damage ratio tends to be larger as story drift angle becomes larger.
