An Evaluation of High-Rise Concrete Building Performance Under Low Intensity Earthquake Effects

The paper presents an evaluation of high rise building in Kedah which subjected to low intensity earthquakes effects. The earthquake study is relevant even though Malaysia is outside the earthquake region but still had experienced and did suffered from major cases in the past like Tsunami. Engineers should concern and consider the loading for reinforced concrete building due to earthquake in Malaysia’s building design procedure. The study addresses on the earthquake study due to performance of critical frame reinforced concrete building. The Quarters Tentera Laut Diraja Malaysia (TLDM) Langkawi, Kedah was chosen as a main model for this study. The building was analyzed using Finite Element Modelling (FEM) under different types of analyses using IDARC 2D depend on variety of earthquake intensities from Time History Analysis (THA) considering low to medium earthquake intensities. The yield point at beam-column connections was analyzed to determine the damage index and damage level of the building. The building performed the early yielding point at 3.115 s for beam element at intensity 0.20 g. Based on result, the critical frame 2A/F–B of the building can stand an earthquake happen with intensity up to 0.20 g. There is no structural damage but some non-structural damage is expected in the non-linear analysis of modal frames which indicates that the building was categorized in the light damage level.
