Damage assessment of high-rise reinforced concrete buildings in peninsular Malaysia subjected to Ranau earthquake

Abstract

This paper shows the analysis of high reinforced concrete buildings in Ranau that have experienced low intensity intensity earthquakes. This study refers to the performance of five (5) high rise reinforced concrete frame when subjected to a variation of low earthquake intensity analysis with 5% damping ground motion measurements. The IDARC software is used to study structures through nonlinear dynamic analysis. Beam-column points are examined to determine damage to the index and to build damage levels subject to varying seismic load. Result shows the first yielding occurred at 4.82 seconds for the beam element at when 0.05g load applied. Based on the result, all buildings cannot withstand seismic load when goes up to 0.2 ground acceleration. It may have arisen that the building is categorized to the extent of the major damage where there is structural affect and structural affect up to 0.15g intensity.
