Abstract | Bangkok, the capital of Thailand, is one of the largest cities in Asia, has never experienced a destructive earthquake. Consequently, large number of buildings have been designed and constructed without any consideration on earthquake loading. Due to the potential risk of having damage causing earthquakes, there is a crucial necessity of evaluating seismic capacity of structures to mitigate the possible hazards during future eaiihquakes. This work presents seismic evaluation of a typical low-rise reinforced concrete commercial building based on the capacity spectrum method (CSM) recommended in ATC-40. To simulate the actual behavior of the building during ground motions, a nonlinear threedimensional FEM model incorporating the effects of foundations, masonry infills, and other site-specific features is constructed. Applying pushover analysis seismic capacity of the structure is determined and compared with the demand imposed by the predicted ground motions. Results indicate that this building possess the most undesirable brittle failure with low level of seismic capacity. Further, this analysis method reveals lots of earthquake vulnerable features and the effectiveness of 3D modeling of buildings with strength and stiffness inegularities. Finally, strengthening of the superstructure is limited by the poor foundation system. |
