“…They are taken from PEER site (PEER, 2015) and the characteristics of these records are given in Table 4. Also, Sa (T1, 5%) is chosen as the spectral acceleration during the period of the first mode along with 5% damping to show the intensity index (Usefvand et al ., 2020). Figure 19 illustrates the design response spectrum along with the ground motion response spectrum and average records.…”

“…The Canadian Standards Association (CAN/CSA S16-01/2001) and AISC Seismic Provisions have accepted SPSW as a structural system resistant to lateral loads (CAN/CSA S16-01/2001; AISC 341–16). In the Canadian Standards Association (CAN/CSA S16-01/2001) and AISC seismic Provisions, the design of SPSWs is similar to a precast tension brace (Usefvand et al ., 2020; CAN/CSA S16-01/2001; AISC 341–16). Details and design code for link beam are provided in the AISC314 based on the type of link beam behavior (Usefvand et al ., 2020; AISC 341–16).…”

PurposeIn this study, the application of a novel combined steel curved damper (SCD) and steel plate shear wall (SPSW) system in the 5-, 10- and 15-storey steel moment-resisting frames (SMR) subjected to earthquake excitation has been investigated. The proposed system is called here as the SMR-WD (steel moment resisting–wall damper).Design/methodology/approachAt the beginning of this research, an SMR-W and an SMR-D are separately modeled in ABAQUS software and verified against the available experimental data. After that, three different heights SMR-WD systems (5-, 10- and 15-storey) are designed and simulated. Then, their performances are examined and compared to the corresponding SMR-W under the effects of six actual earthquake records.FindingsThe obtained results show that the proposed system increases the mean values of the base shear for 5-, 10- and 15-storey SMR-WD equal to 27, 20.15 and 16.51%, respectively compared to the corresponding SMR-W. Moreover, this system reduces the drift of the floors so that the reduction in the average values of maximum drift for 5-, 10- and 15-storey SMR-WD is equal to 10, 7 and 29%, respectively with respect to the corresponding SMR-W. The results also reveal that the considered system dissipates more energy than SMR-W so that the increase in the mean values of the energy absorption for 5-, 10- and 15-storey SMR-WD is 30.8, 25.6 and 41.3%, respectively when compared to the SMR-W. Furthermore, it is observed that SMR-WD has a positive effect on the seismic performance of the link beams and panel zones of the frames. By increasing the height of the structure in the SMR-WD, the energy dissipation and base shear force increases and the drift of floors decreases. Hereupon, the proposed SMR-WD system is more useful for tall buildings than SMR-W frames.Originality/valueFor the first time, the application of a novel combined steel curved damper (SCD) and steel plate shear wall (SPSW) system in the 5-, 10- and 15-storey steel moment-resisting frames (SMR) subjected to earthquake excitation has been investigated.
