This paper investigates numerically the seismic behavior of multi-degree-of-freedom (MDOF) systems with novel 2–4 direction and displacement-dependent (2–4DDD) Displacement-Velocity- (2–4DVD) Semi-Active (SA) controls. study builds upon SA 2–4DDD control system, in which damper forces are controlled by inter-story drifts. For first time, this an MDOF system A 3-story steel frame is modeled OpenSees then subjected to real earthquake records. The considering three systems: (i) conventional passive nonlinear viscous dampers (NVDs), (ii) dampers, (iii) a new 2–4DVD damper. Parametric studies conducted determine optimal parameters designed frames. New design methodologies for controls also proposed. results discussed terms drift, base shear force, acceleration, dissipated energy required force. Results from Nonlinear Time History Analyses show that, compared traditional NVDs, drifts up 72% 32% lower, respectively. reduces damping acceleration 60% 87%, respectively, control. It shown that was not stable high-frequency Conversely, leads smoother force changes between quadrants case investigated paper. contributes toward development retrofitting systems.

Abstract It’s crucial to keep bridges safe and operational all the time. Before or after an earthquake, they may require immediate seismic retrofitting. In this situation, adopting both isolation systems viscous dampers could be used as a solution. Therefore, performance of RC bridge with linear nonlinear at pier tops abutments is investigated. The selected model Incesu Bridge in Artvin province north–eastern Turkiye. model, elastomer bearings (EBs) (VDs) are added piers (i.e., deck connection points). results revealed that maximum bending moment two significantly reduced compared case where pier’s fixed its deck. However, large level damper coefficient cause structural damage under strong design earthquake.
