چکیده:
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.

چکیده:
The Steel Plate Shear Wall with Coupling (SPSW-WC) system consists of a pair of planar SPSWs linked together with coupling beams at the floor levels. The degree of coupling, which represents the level of interaction between the two piers, and the plastic strength for a SPSW-WC are important parameters in understanding behavior and developing designs for the system. This paper examines these two parameters using plastic analysis and numerical simulations of single story and multi-story SPSW-WC configurations. The focus is on desirable uniform-yielding mechanisms, but soft-story mechanisms are also briefly discussed, and analytical closed-form expressions are developed for ultimate strength and degree of coupling. Thirtytwo SPSW-WC structures are designed with emphasis on varying the following parameters: height of the structure (number of stories), coupled length and coupling beam properties. These structures are studied with numerical models using monotonic nonlinear static analysis. Good agreement is observed between the numerical simulations and the analytical predictions for the ultimate strength and degree of coupling. The degree of coupling is shown to have a significant impact on structural weight, particularly for the taller structures studied, and the optimal degree of coupling to maximize material efficiency is found to be in the range of 0.4 to 0.6.
