     the response modification factor r represents a number of structure behaviors including ductility, overstrength and the inherent redundancy. thus, this factor is to be defined according to the type of lateral force resisting system. however, there are some complexities and/or uncertainties with regard to the codes related to the r factor in terms of height, form of irregularities and structural systems. in the present study, assuming a low-rise, vertically irregular structure with a heliport and a dual structural system, and applying a complete design, including a nonlinear finite element approach, pushover analysis, and implementation of different codes, an extensive investigation of the r factor has been conducted for different orientation of concrete core and/or irregularities in structure. it is expected that with the help of to this wide-ranging study, we can come up with an appropriate and reasonable understanding of the r factor in these types of structures
