| Abstract | More apparent natural disasters that hit the country on a more regular basis, consideration of earthquake as a serious design condition has long been overlooked in most of the developing countries. The increased regularity and intensity of earthquakes over the countries, poor performance of traditional buildings have raised awareness about earthquake resistant design (ERD). However, many Reinforced Concrete (RC) building structures in most of the developing countries are still designed for vertical loads only with nominal reinforcement details, according to non-seismic detailing practices.When it's come to the structural design engineering, the selection of the frame systems holds the significant impact on structural stability, resilience and safety of the buildings. Among various options, Ordinary Moment Resisting Frame (OMRF), Intermediate Moment Resisting Frame (IMRF) and Special Moment Resisting Frame (SMRF) stand out as key players while offering the unique characteristic of each frame. The major aims of this research are to explore the story level and component level responses of OMRF, IMRF and SMRF under the same DBE level earthquake by applying Linear Response Spectrum Analysis method. Furthermore, Nonlinear Static Pushover Analysis will conduct to see the seismic performances of OMRF and SMRF under same lateral forces push in both X and Y-direction of the buildings. Linear and Non-linear analysis were conducted to compare the seismic demands and the responses of OMRF and SMRF.The linear analysis results show that the displacements in SMRF are higher than OMRF and IMRF while the base shear of OMRF is highest among 3 frames. Nonlinear static pushover analysis results shown that SMRF performance can undergo large displacements without significant loss of strength. OMRF have limited ductility tends to be resist higher forces but may not perform well beyond elastic limit, leading to brittle failure. |
