dc.description.abstractThe deflection amplification factor (Cd) is an important parameter in seismic design. Cd is essential in seismic design according to the American Society of Civil Engineers minimum design load standards (ASCE7-16) especially for the drift check and for the calculation of the seismic separator distance. Contractors face difficulty in implementing seismic separation, especially in high-rise buildings. The seismic separator is computed in ASCE7-16 depending on the Cd factor by calculating the inelastic displacement, which is crucial for calculating the seismic separation. Cd remains constant for the same structural system, as per ASCE7-16, regardless of the building characteristics such as (time period which depends on span length, story height and numbers of bays). The goal of this work is to obtain a Cd value for each building based on the building’s characteristics, which helps in reducing the width of the seismic separator, especially for high-rise buildings. To achieve this goal, various parameters associated with building characteristics that may influence Cd value were studied. 36 case studies of square-shaped building models with varying numbers of floors, floor height, span length, and the number of bays were analyzed using both linear and nonlinear time history analysis. Three-time history records that match the response spectrum in SAP2000 and seismomatch are used to compute Cd. On the other hand, the computer software, ETABS was used for the structural design considering both gravity and seismic loads. Results from the analysis show that ASCE 7-16 is conservative in presenting Cd values and that Cd varies depending on the characteristics of the building. The results show that the value of Cd decreases with increasing span length, story height, number of bays, and time period (Tn). The results of this study were used to develop an equation to estimate Cd based on the building characteristics. Keywords: Deflection amplification factor, Cd, SMRFs, Time history, Response Spectrum, nonlinear displacement, liner displacement, fiber hinge.
