Comparison of performance analysis of a moment resisting framed structure according to tbdy 2018 and asce 41-17

Abstract

Due to its simplicity, nonlinear static procedure (NSP) or pushover analysis has been using for the determination of the nonlinear performance of structural and non-structural members. While modeling the determination of the nonlinear properties and deformation capacities for each component of the structure should be determined. Pushover analysis is carried out for either user-defined nonlinear hinge properties or defaulthinge properties, available in some programs based on the TBDY 2018 and ASCE 41-17 standards. Assigning the incorrect default-hinge properties may lead to unreasonable displacement capacities for existing structures. In this study the performance analysis of a single span structure was performed according to TBDY 2018 and ASCE 41-17 codes and the results were compared. Number of stories of the structures were changed for the parametric study. Capacity curves have been obtained as a result of the analysis performed on the building systems. The peak displacement amount calculated according to ASCE 41-17 was obtained more than the peak displacement amount calculated according to TBDY 2018. The amount of base shear force and story shear forces calculated according to TBDY 2018 has been obtained more than ASCE 41-17. The most effective parameters for the plastic hinge properties are plastic hinge length and transverse reinforcement spacing. The results of analyses obtained from the TBDY 2018 and ASCE 41-17 codes show that the structural performance depends on the number of vertical loads, effective stiffness of the structural members and plastic hinge properties.
