Maximum response estimation of a mid-story isolated building based on complex complete quadratic combination method considering mode-dependent peak factors

Abstract

Many researchers have investigated the vibration characteristics of mid-story isolated buildings. However, a formula to estimate their maximum responses has still room for improvement. A complex complete quadratic combination method is reformed using mode-dependent peak factors. The response of a mid-story isolated building model under white noise ground motion is analyzed and it is confirmed that the reformed formula gives slightly larger, safer-side estimates in most cases.
