ANALISIS KINERJA STRUKTUR PADA BANGUNAN BERTINGKAT TIDAK BERATURAN DENGAN ANALISIS DINAMIK MENGGUNAKAN METODE ANALISIS RESPONS SPEKTRUM

Agus Hariyanto, 2011. Peformance Analysis on The Structure of Irregular Multistory Building with A Dynamic Analysis Using Respons Spectrum Analysis Methode. Earthquakes frequently hit Indonesia, many caused thousands of casualties and damage to buildings. Earthquakes often occur because Indonesia was in two regions of the Pacific seismic lines (circum-Pacific Earthquake Belt) and the path of asia earthquake (Trans Asiatic Earthquake Belt). The earthquake caused damage to building structures. When an earthquake happens, the building is expected to be able to accept a certain level of earthquake forces without any significant damage to the structure. In general, seismic analysis is divided into two major parts namely the earthquake analysis of static and dynamic earthquake analysis. In buildings that are very high, irregular, and the multistory buildings that require a very large used precision planning of dynamic analysis, which consists of the analysis range of the response spectrum and time history dynamic response analysis. This study aims to determine the safety of the building seen from the displacement, drift and shear bash. The method used is the dynamic response spectrum analysis using ETABS program. Maximum total drift in the X direction is 0.00825 m and the Y direction is 0.00588 m, so the building is safe against the ultimate limit of performance (0.02h) and serviceability limit the performance of {(0.03 / R) xh}. Value of displacement in the X direction is 0.06941 m and the Y direction is 0.05274 m, so the displacement at the building does not exceed the maximum displacement, so that the building is safe against earthquake plan.
