| Abstract | Over 7000 earthquakes have been recorded around the world since the 1900s. Earthquakes cause high levels of damage to all structures. Out of these, high rise buildings have a high probability of being affected by seismic activity. Most structures in Thailand have been designed based on gravity designs. Due to this they are at a higher risk of being damage by seismic loads. This report is mainly focused on the seismic performance of 8 storey reinforced concrete structure which is located in the northern part of Thailand. In this assessment, mainly nonlinear finite element software called OpenSees is used to develop the nonlinear finite element model and to conduct the analysis process. Three damage limit state values have been defined by using the nonlinear static pushover analysis. In addition to this software, a software called seismo signal have been used to obtain the spectral acceleration values for 1st mode period of the structure. Finally, fragility curves have been developed by using these data and inter-storey drift values. They are utilized to ascertain the probability of the aforementioned damage limit states occurring in the building for specific spectral accelerations. With this information it will be possible to predict whether a structure needs retrofitting or not. In some cases it may show that the building has to be demolished. According to the results obtained from fragility curves, this reinforced concrete structure has a higher probability values for immediate occupancy level and life safety level than collapsing prevention level for all recorded spectral acceleration values. |
