“…As shown in Table I, the review covers various design codes such as North American design codes for instance ACI (Committee, 2008), UBC (Conrad and Winkel, 1998), IBC (Code, 1997), ASCE (Vesilind, 1995), AISC (Muir and Duncan, 2011), NBC (Canada, 2015;Code, 1990), and CSA (Association, 2005), South American codes, for example, NBR (NBR, 2006), NSR (Galíndez and Thomson, 2007), CEC (Canchig Cola, 2016), and NCh (Guendelman, Saragoni and Verdugo, 2012), Asian codes such as IS (Haldar and Singh, 2009), BSLJ (Itabashi and Fukuda, 1999), NZS (Authority, 1992), BNBC (Islam, et al, 2011), NBC India (de León, 2010), NSCP (Deepshikha and Basu, 2011), ICS (Habibi and Asadi, 2013), TEC (Şengöz, 2007), OSC (Al-Sayed and Waris, 2017), ISC (Amer, Sobaih and Adel, 2016), and SBC (Shuraim, et al, 2007), European codes like EC (Gulvanessian, Calgaro and Holicky, 2012), BS (Arya, 2018), African codes such as ECP (Committee, 2007), RPA (Belazougui, 2017), and Australian code AS (Menegon, et al, 2018).

Building design codes (BDC) are used to control the construction industry in general and building design in particular. The BDC offers the construction sector with a standard language and set of requirements. There are several BDCs developed and utilized for construction purposes throughout the world. Certain design codes are employed in structural design to assure the structure’s health and safety, as well as its cost-effectiveness. It also assures that the structure is sufficiently sturdy to endure all potential climatic conditions, bear its intended load, and is integrated to ensure effective use of building materials and resources. This research aims to compare various building construction design codes to identify and explore the most appropriate standard in terms of safe design, economics, and availability of details. In Kurdistan and different parts of Iraq, many international companies have designed building structures with various codes during the past 20 years. This is a bad condition since the government has no control over the construction of the buildings, which includes both the code and the building materials. There is currently no overview of the design codes in use in Kurdistan, nor is it clear whether they are congruent with what students’ study in institutions.

“…Based on this precedent studies, simplified expressions and procedures to evaluate the response modification factors (R) for steel moment resisting frames are suggested in this study. Several researchers performed the nonlinear incremental dynamic analysis or time history analysis to evaluate the ductility and strength factors (Kim et al, 2005;Galíndez et al, 2007;Asgarian et al, 2009;Kurban and Topkaya, 2009). It would be required a lot of effort and time to carry out the nonlinear dynamic or time history analysis.…”

“…Kim and Choi (2005) evaluated the overstrength, ductility and response modification factors of the chevron type concentric braced frames by performing pushover analysis of model structures with various stories and span lengths. Galíndez and Thomson (2007) estimated the response modification factors for Colombian code compliant steel moment frame buildings of different heights (3-, 7-, and 11 stories), located in a high-risk seismic region. The response modification factor was evaluated and found to be five times lower than that recommended by the code for a seismic design demand level.…”

The design force levels currently specified by most seismic codes are calculated by dividing the base shear for elastic response by the response modification factor (R). This is based on the fact that the structures possess significant reserve strength, redundancy, damping and capacity to dissipate energy. This paper proposed the evaluation methodology and procedure of the response modification factors for steel moment resisting frames. The response modification factors are evaluated by multiplying ductility factor (R µ ) for SDOF systems, MDOF modification factor (R M ) and strength factor (R S ) together. The proposed rules were applied to existing steel moment resisting frames. The nonlinear static pushover analysis was performed to estimate the ductility (R µ ), MDOF modification (R M ) and strength factors (R S ). The results showed that the response modification factors (R) have different values with various design parameters such as design base shear coefficient (V/W), failure mechanism, framing system and number of stories.

“…Many scholars found that the response modification factor relates to the ductility and overstrength of a given structure [4][5][6][7][8][9][10].In the well-known documents such as ATC(1995), he response modification factor was calculated as the product of three factors: overstrength factor, ductility factor, and redundancy factor. FEMA695 (2008) points out that the redundancy factor becomes unity for structures designed using an ultimate strength method.…”

In current seismic design procedure, structure base shear is calculated according to the linear elastic response spectra divided by the response modification factor, which accounts for ductility and overstrength of a structural system. In this paper, the response modification factors of Y-eccentric braced steel frames (YECBF) designed based on Chinese Code were evaluated by an improved pushover analysis on 12 examples with various stories and spans lengths. According to the analysis results, the effects of fundamental periods, storey numbers, and spans of frames on the behavior factor were studied. In the end, an appropriate response modification factor was proposed for YECBF designed base on Chinese Code.
