Comparison of tsunami and earthquake loadings on a reinforced concrete shear wall building_Lim Chee Hin_A9_2011_NI
Tsunami dan gempa bumi ialah dua bencana alam berlaku di seluruh negara dan impak dibawa oleh mereka ialah kerugian ekonomi dan nyawa manusia. Dinding ricih yang mempunyai kekuatan tinggi dan ketegaran menjadi salah satu sistem struktur yang sesuai untuk menentang daya sisi. Terdapat banyak bangunan tahan tsunami atau gempa bumi telah direka bentuk untuk pemindahan atau perlindungan bagi menyelamatkan nyawa manusia. Bagaimanapun, tiada atau sebilangan kecil bangunan yang dapat menentang kedua-dua jenis daya. Maka, kajian ini fokus pada siasatan kelakuan struktur bangunan dinding ricih terhadap kedua-dua jenis daya tersebut. Konsep dinding yang mudah terhancur telah diperkenalkan dalam kajian ini untuk meminimakan kesan daya tsunami. Dua gabungan daya tsunami iaitu, seretan hidrodinamik dengan daya impak dan seretan hidrodinamik dengan daya pengempangan puing. Analisis ini melibatkan tiga jenis ketinggian bangunan dinding ricih iaitu rendah (dua tingkat), sederhana (lapan tingkat) dan tinggi (lapan belas tingkat) dan kelakuan struktur yang berbeza telah diperolehi. Untuk bangunan yang rendah, pengiraan beban tsunami adalah sedikit dan oleh itu menyebabkan impak kecil pada bangunan. Untuk bangunan dinding ricih yang tinggi, beban gempa bumi ialah faktor utama dan menunjukkan keperluan untuk dipertimbangkan. Keseluruhan, pereka perlu menimbangkan beban gempa bumi daripada beban tsunami dalam reka bentuk terutama bangunan dinding ricih yang tinggi. Untuk bangunan yang rendah, pereka boleh menimbangkan kes kawalan dengan faktor muatan yang mencukupi untuk mengatasi keadaan yang tidak menentu seperti daya tsunami yang tidak dapat diduga. ___________________________________________________________________________________ Tsunami and earthquake are two natural disasters occurring all over the world and the impacts brought by them are huge and causes enormous loss in economic and human lives. Shear wall which has high strength and rigidity thus become a suitable structural systems to resist the lateral forces. There is a lot of tsunami or earthquake-resistant buildings have been designed for evacuation or shelter purpose to save the life. However, there is no or small number of building designed to resist both types of loadings. Hence, this study focused on the investigation of the structural behaviour of shear wall building subjected to both types of loadings. The breakaway wall concept was introduced in this study to minimise the effect of the tsunami forces. Two combinations of tsunami forces were considered namely, hydrodynamic drag with surge force and hydrodynamic drag with debris damming force. The analysis involved three different height of shear wall building namely low (two-storey), medium (eight- storey) and high (eighteen-storey) rise building and different structural responses were obtained. For low rise building, the computed tsunami load was small and hence resulted in small impact on the building. For medium and high rise shear wall building, the earthquake load is dominance and prudent care need to be taken into consideration. Overall, the designer should consider the earthquake load rather than tsunami load in design especially the high rise shear wall building. For low rise building, designer can consider the control case with sufficient load factor to overcome any uncertain circumstances such as underestimation of tsunami forces.
