Abstract

At present seismic evaluation of structures has become very crucial in Bangladesh as the country is in earthquake prone region. Lots of studies have been performed and many methods have been proposed for the rapid seismic evaluation of reinforced concrete (RC) buildings. Over the past two decades the country has been going through an important evolution which is rapid construction of pre-engineered steel buildings (PEB). Unfortunately, there has not been a single research work done or any method proposed for the seismic evaluation of these type of structures. In this work, simplified structural evaluation which is based on Japanese Index Method has been used for the seismic evaluation of 05 existing PEB steel structure. The structural seismic index of the building, IBS has been compared with the seismic judgement index IBSO which is a function of seismic zone co-efficient, structural importance coefficient and normalized acceleration response spectrum. The service load index IBD has also been compared with service load judgement indices, IBD01 and IBD02 which has been calculated from the material strength. For example, from the judgement of one building at ground floor, 0.5IBSO ≦ IBS＜IBSO and IBD02＜IBDhave been observed hence immediate detail evaluation recommended.
