“…In a study on examining the impact ofsheet placement and changes in wave's characteristics on behavior of wavy steelshear wall, it was observed that steel shear wall capacity increased if waveswere aligned with beams. Also, resistance of steel shear walls increases as wavelength decreases and wave depth increases (Ashrafi et al, 2018).…”

One of the most significant parameters which should be considered by all engineers is improving structures’ strength subjected to lateral load. Steel shear wall whose duty is to affect lateral load (wind and earthquake) is a wall which consists of shear part. Application of low yield point (LYP) steel in shear walls allows the employment of moderate and/or stocky infill plates with low yielding and high buckling capacities, which can result in enhanced buckling stability, serviceability, and energy dissipation capacity of such systems. Infill LYP plate is used to improve shear wall behavior which leads to enhancement of stiffness. In the present research, infill plate with spherical appendages is applied, and its impact on plate stiffness, cyclic behavior and energy absorption are investigated. The spherical diameter has been chosen respectively 10 and 20 cm distributed with two patterns (diagonal and plus form). The best performance is for a LYP plate with a 10 cm spherical diagonal pattern.

“…One of the most important parameters that should be investigated for structures such as bridges is the effect of impact loads due to vehicle accidents, causing progressive damages to bridges and the effect of cyclic loading due to earthquake force (Sayyar-Roudsari et al, 2018b;Soleimani et al, 2015). Moreover, (Sayyar-Roudsari et al, 2018a) have investigated comprehensive numerical and finite element studies by MATLAB and ABAQUS to identify the damage to concrete bridges and presented reinforcement strategies by composite fibers (Sayyar-Roudsari et al, 2018b;Ashrafi et al, 2018) using finite element method, have examined the nonlinear behavior of wavy steel shear walls. The optimal shape of tall arched concrete dams and concrete open arched bridge is obtained using ANSYS FEM software by (Pouraminian et al, 2017;.…”

In recent years, the issue of lower computational cost and analysis time has been the important factors for the structural analysts. In the meantime, after years of its introduction as an analysis having features of nonlinear analysis, the Fast Nonlinear Analysis (FNA) claims to have a higher performance speed than other nonlinear analyses, but has been less used by the researchers in this field. This research is conducted in order to improve the accuracy of the claim for a significant difference between the duration of structural analysis using the FNA method in comparison with the Nonlinear Time History Analysis (NLTHA) in Sap2000 software. RC frame with two seismic resistant systems of Moment Resistant Frame (MRF) only and MRF equipped by visco-elastic dampers (MRF-VD) and efficiency of the FNA method has been investigated. The results indicated that in the analysis time, the structural analysis is decreased by 7-9 times, while the seismic fragility curves calculated for performance limit state of the frame does not provide an accurate estimate of the damage to the frame.
