Determining Coefficient Behavior of Reinforced Moment Frame Having the Steel Plate Shear Wall using incremental Non-linear Dynamic Analysis (IDA)

Nowadays the researchers and experts are interested in steel plate shear wall throughout the world particularly in the regions with high frequency of earthquakes. There has been a number of numerical and experimental studies to get more information about the behavior of this system.to make more use of the capacity of inelastic behavior of the systems and structures it makes necessary to apply Non-linear methods in designing structures. As this method is rather time-consuming the static linear technique is used instead of it, designing elastic is not economical, so it is replaced by coefficient behavior. In this study, the seismic coefficient for the reinforced concrete moment frame with the thin steel plate shear wall is carried out using incremental nonlinear dynamic analysis. Three 7-story, 15-story, and 30-story buildings with different near fault and far fault records were analyzed. The ductility factor, additional strength, and coefficient behavior of the structure were calculated as 4.24, 2.48,9 respectively. The result of this study show that the coefficient behavior, and ductility factor of this system is decreased as the height of the structure goes up but it leads to the increase in the strength Factor.
