COMPARISON OF MRF AND CBF STRUCTURAL RESPONSE TO EARTQUAKE IN OFFICE BUILDING SURABAYA

Indonesia is a country that prone earthquakes. Therefore, knowledge of earthquake-resistant building construction needed in reducing the risk damage caused by There are several methods planning, one which pushover analysis method. Pushover nonlinear static method structure subjected to gravity loading and displacement-controlled lateral loads continue increase through elastic inelastic behavior until final condition. One popular materials structural planning steel construction, has uniform structure, lightweight, strong, easy work with. In modeling structures, models MRF CBF models. configuration model configured on beams firmly connected columns. Based rigid beam-column connection, moment frame cannot be moved laterally without bending beam or column depending connection geometry. Results The case study comparison two concluded design structures using method, it was found had higher ductility than CBF, namely 2.1:1.6.
