“…Moreover, Mehanny and El Howary [34] and El Howary and Mehanny [35] focused on the buildings designed based on the Egyptian seismic code. Finally, Duan and Hueste [36] investigated the seismic performance of a multi-story RC-frame building designed according to the provisions of the current Chinese seismic code, GB50011-2010. Astriana et al [37] utilized fragility curves in order to compare the seismic performances of moment-resisting frames and frame-wall systems.…”

Structural collapse is the main concern for the existing structures which are built in the seismic-prone regions. Therefore, the primary goal of the seismic provisions in building codes is to prevent the global collapse. Iran is located in the Alpine-Himalayan belt, and has experienced some of the most destructive earthquakes in the past century. To evaluate the extent to which the Iranian building code provisions meet the abovementioned objective, the authors conducted a detailed assessment of collapse risk on a set of moderate moment resisting Reinforced Concrete (RC) buildings. While many features might a ect the seismic performance of the RC structures, this study considers P e ects, deterioration in strength and sti ness, and cyclic deterioration in structural components. Structural assessment was performed using OpenSees platform and the multiple-record Incremental Dynamic Analysis (IDA). Results were obtained in terms of IDA capacity curves and collapse fragility functions at di erent seismic hazard levels. Results showed that probability of instability increased with height of the buildings. Moreover, the collapse con dence level was evaluated considering the available uncertainties. Assuming a minimum con dence level of 90% for the buildings, the Collapse Prevention (CP) Limit State (LS) under the 2%/50 yr hazard level was not satis ed for the 9-and 12-story frames, and they needed to be redesigned .

Failure mode of reinforced concrete (RC) structures are classified according to tension reinforcement ratio of beam elements. To determine effect of tension reinforcement ratio on performance of RC structure, two planar RC structure were selected. One of them is 5 stories other of them is 7 stories. Two different concrete class, C20 and C25, were considered for analysis. Three tension reinforcement combinations were considered, three different tension reinforcement ratios were used. First case is the ratio of the tension reinforcement is lower than that of the compression reinforcement, second case is the ratio of the tension reinforcement is equal to the ratio of the compression reinforcement and third case is the ratio of the tensile reinforcement is higher than the compression reinforcement.

“…Duan and Hueste investigated earthquake behaviour of a five-story reinforced concrete building designed according to the requirements of the Chinese seismic code. They used the distributed hinge model in these analyses [20]. Kadid et al investigated behaviour of reinforced concrete buildings under simultaneous ground motions using the fibre hinge approach [21].…”

The existing reinforced concrete (RC) buildings are analysed in the paper before and after shear-wall retrofitting. For numerical application, an existing RC building was selected and retrofitted with shear walls. Incremental dynamic analyses and static pushover analysis of these buildings were performed using the distributed plastic hinge approach. The results show that seismic retrofitting with shear walls increases rigidity and capacity of the building, while decreasing lateral displacements and damage.
