Seismic evaluation of low to meduim rise of regular rc building

Seismic evaluation of low to meduim rise of regular rc building / Siti Hajar Noor Aidy
Gempa bumi berlaku disebabkan oleh pembebasan tenaga secara mendadak atau pergerakan yang tidak dijangka dari permukaan bumi. Tsunami yang berlaku pada 24 Disember 2004 yang disebabkan oleh gempa bumi bermagnitud 9.1 telah membawa kepada kerosakan bukan sahaja kepada struktur bangunan tetapi juga kepada kehidupan manusia. Kajian dalam prestasi seismik telah dilaksanakan sejak beberapa dekad yang lalu untuk menilai risiko dan kelemahan seismik di bawah gempa bumi. Objektif kajian ini adalah untuk menentukan prestasi 3D sekata ‘Moment Resisting Concrete Frame’ (MRCF) di bawah peruntukan seismik. Analisis statik tidak linear dan dinamik telah digunakan dalam kajian ini untuk menilai prestasi bangunan rendah ke sederhana bagi bangunan konkrit tetulang. Analisis ini menyediakan maklumat dalam menilai prestasi bangunan struktur di bawah gempa bumi. Kajian ini menggunakan struktur 3D untuk mewakili bangunan sebenar di bawah beban seismik. Tiga tingkat yang berlainan, N: 3, 6, dan 9 telah digunakan untuk model struktur di mana beberapa parameter telah diambil dari Hatzigeorgiou and Liolios (2010). Tujuh gerakan tanah tunggal telah dikenakan untuk mewakili gerakan seismik tanah. SAP 2000 dan STERA 3D adalah perisian yang digunakan untuk analisis. Keputusan dari analisa ‘pushover’ telah menunjukkan bangunan sembilan tingkat mempunyai peratusan drift yang paling tinggi berbanding bangunan tiga dan enam tingkat. ‘Drift shear relation curve’ menyatakan tentang tingkat tinggi mempunyai anjakan tertinggi. ‘Incremental Dynamic Analysis’ (IDA) menunjukkan anjakan bangunan meningkat apabila ada peningkatan dalam PGA Ini membuktikan yang setiap gerakan gempa bumi mempunyai nilai anjakan yang berlainan untuk bangunan. _______________________________________________________________________________________________________ Earthquake is caused by the sudden release of energy or an unexpected movement from the earth surface. Tsunami that occurred on the 24th December 2004 caused by earthquake with a magnitude of 9.1 had brought damages not only to structural buildings but also to human lives. Research on seismic performance had been carried out over the past decades to evaluate the risk and seismic vulnerability under earthquake. The main objective for this study is to determine the performance of regular 3D moment resisting concrete frame (MRCF) under seismic provision. Nonlinear static and dynamic analysis had been used in this study to evaluate the performance of low to medium rise RC building. These analysis provide information in evaluating the performance of the structural building under earthquake. This study implemented 3D structure to represent real building under seismic loading. Three different storey, N: 3, 6, and 9 were used as the structural models which some of the parameters used were adopted from Hatzigeorgiou and Liolios (2010). Seven single ground motions data were employed to represent the seismic ground motion. STERA 3D and SAP 2000 software were used to run the analysis. Results from the pushover analysis shows that nine storey has the highest percentage of drift compared to three and six storey. The drift shear relation curve exhibited that higher storey levels has the highest displacement. The Incremental Dynamic Analysis (IDA) shows that the displacement of the building increases when there is an increase in PGA. It can be proved that each earthquake ground motion has a different value of displacement for the structure.
