PREDOCTION OF MAXIMUM INTER-STORY DRIFT ANGLES IN CONVENTIONAL BRACED STEEL FRAMES

Abstract

This research is concerned with the seismic design of conventional braced steel frames. During earthquakes, the steel brace in buildings behave with some problems. To be more precise, they cause buckling under compression and slip under the tension. This study proposes a method of predicting the maximum inter-story drift angles for steel frames with conventional steel braced on the principle of energy balance. This paper aims to develop a utilization of conventional braces as a vibration control system to reduce the maximum inter-story drift angles during earthquakes.
