Comparison Study on Damage Pattern of Two Stories Building: Simulation vs Field Record

Abstract

A study on the damage pattern of the two-story building is needed for quick assessment soon after the earthquake. In Indonesia, quick assessment is needed at least for two reasons: to determine the Government subsides Fund and to retrofit the damaged houses. The previous article has been analyzed and simulated the case study of the two-story building due to earthquake load base on Indonesia Earthquake Code by considering the soil conditions. It shows that the influence of soil conditions as well as column properties, especially at a lower level, are an important factor in determining the damage patterns. However, that study was not verified yet with the damage data of the two stories building in the field. This paper discussed the comparison between the simulation results with the field record of two stories building damage in Indonesia. The data are collected base on the recent earthquakes in Indonesia: Padang Earthquake ( 2009) and Palu Earthquake (2018). It shows that they are confirmed the damage patterns are in line with the simulation results. Base on this study, the guidance for quick assessment of a two-story building then is developed.
