| description | Malaysia is under the menace of earthquake event. Despite its weakness in resisting seismic excitation, soft storey building still gains its popularity due to the functional and aesthetic purpose, which has always been the preference for hotelier and shopping complex. Nonlinear Static (Pushover) Analysis (POA) is time saving and simple
assessment procedure in Eurocode 8 (EC8), however, its reliability in designing structure remains a question. It is the same for fragility curve produced by using SPO2FRAG
through POA. Therefore, Nonlinear (Incremental) Dynamic Analysis (IDA) is used as a reference for results generated POA. This study is to assess seismic performance of
building using POA in EC8. Also, empirical accuracy of fragility curve generated by POA (using SPO2FRAG) is studied. Regular and soft storey of 5- and 11-storey frames
that composed four models of varying height were designed according to Eurocode 2(EC2) for sizing and reinforcement of structural member, while EC8 is used to determine
earthquake loading. SAP2000 software was used to carry out POA. Capacity curve obtained is served as main input in SPO2FRAG software, which generate fragility curve
based on results of POA. Then, IDA is performed to generate IDA curves and fragility curves. Peak ground acceleration, PGA was converted into corresponding Sa (T1) using
design spectrum from EC8. Performance level of Life Safety (LS) and Near Collapse (NC) proposed by Vision-2000 (1995) are the main interest in this study. Results from
POA and IDA shown that soft storey frame has higher demand than regular one. Fragility curve generated by POA (using SPO2FRAG), indicated that regular 5-storey frame can
capture the trend of fragility curve of IDA, but some deviation is observed for soft storey structure (5-storey). All 11-storey frames shown unsatisfactory match of fragility curve from what was generated by POA, compared to IDA. |
