Suitability Of Dbela Methods As Seismic Vulnerability Assesment For Buildings In Kota Kinabalu, Sabah

Sabah experienced moderate seismicity in the active fault zones located in Kundasang, Ranau of 6.0 MW within minor damage recorded at Sabah recently. The damage following the earthquake and more than 100 aftershocks affected 61 buildings such as schools, hospital and mosque, 22 roads and 22 slopes. Over the past 114 years, a total of 124 with magnitudes ranging from 2.9 to 6.0 are known to have occurred. The earthquake in Sabah that struck Ranau, carrying a moment magnitude of 6.0 on 5 June recently lasted for 30 seconds. This earthquake was the strongest to affect Malaysia since 1976 in Lahad Datu. The latest thesis in the Sabah region had been carried out in Kundasang, Kudat and two buildings in KK city. The objective was to presents the evaluation of soil sample taken in Kota Kinabalu (KK) city that could possibly subjected to low intensity earthquake effects. The evaluation of determination of the soil amplification factor is used to determine the influence of soil condition on buildings in KK city. With the input motion of Whittier Narrows (6.0 Mw, ts = 0.005 s) and KKM Ranau (5.9 Mw, ts = 0.01 s), the analysis of the maximum acceleration for PGA and PSA will be varies with the use on program of NERA and DEEPSOIL V5.1. From the appendixes as shown in appendix, it is known that most of their soils are consisting of a surface alluvium layer varying the thickness in between of approximately 5 m and 20 m in refer to some researcher. Most of the soil condition is reviewed that there are soil type of B, C, D and E in according to (Technical Committe B/525, 2005). This study shows that the soil amplification factors for each location in KK city are various with the input motion of 5.9 Mw, ts = 0.01 s and 6.0 Mw, ts = 0.005 s.
