| dc.description.abstract | All structural systems are not treated equally when the response to earthquake-induced forces
is of concern. Structural configuration, symmetry, mass distribution, and vertical regularity
must be considered. The importance of strength, stiffness, and ductility in relation to acceptable
response must also be appreciated. While considering the lateral force resisting systems, we
came up with many options to have structural systems like Bearing wall systems, Moment
Resisting frames, and Lateral Bracing systems, designing the moment resisting concrete frame
structures we have the option to use IMRF, OMRF, or SMRF. The basic step in conceptual
design is to find the best suitable framing system and then lateral load-resisting mechanism,
while designing structures it is often found to be complicated to make decision of Response
Modification Factor (R), which is a measure of ductility and over-strength of the structures. It
is used to find the base shear, which is distributed on different stories. SMRF and IMRF are
emphasized in the research and a detailed computer simulation of the different RCC structures
in Zone-II with different R-values i.e., 5 and 8 given in BNBC-2020 are used. In this study,
there are a total of 3 models of different frame systems are developed and several comparisons
are made among them, such as drift, displacement, sway, column and beam Size comparison,
longitudinal reinforcement requirement comparison, column cost analysis, and base shear
comparison. Conclusions are drawn from the study after all the comparison analysis it is found
that the SMRF frame system is a better and more effective framing system than the other two
framing systems such as IMRF and OMRF. | en_US |
