Abstract | In this study, the performance evaluation of twenty-two reinforced concrete buildings from Dhakha, Bangladesh is examined. To select the representative reinforced concrete buildings, Comprehensive Disaster Management Programme (CDMP), the report on vulnerability assessment of Dhaka, Chittagong, and Sylhet is used. The member characteristic of all reinforced concrete buildings are analyzed from the surveyed data and drawing. It is found that the buildings have similar structural characteristic: similar longitudinal reinforcement ration, similar member length, similar axial load ratio, similar infill wall thickness, similar slab thickness, and similar story height. The seismic performance of these twenty-two reinforced concrete buildings is evaluated by using the pushover analysis (capacity spectrum method) procedure which is based on the assumption of the fundamental mode of vibration is the predominant response of the structure. The seismic evaluation results (capacity curves) are presented in terms of spectral displacement and spectral acceleration. The performance point which is the maximum response of building is defined by intersecting the capacity curve and demand spectrum. The study adopted the HAZUS methodology to define fragility functions by describing Slight, Moderate, Extensive, and Complete damage states. At the point of the performance point of spectral displacement, the probability of being in or exceeding a particular damage state can be checked. |
