In regions prone to seismic activity, buildings constructed on soft soil pose a significant concern due their inferior performance. This situation often results in considerable structural damage, substantial economic loss, and increased risk human life. To address this problem, study focuses the retrofitting of steel moment-resisting frames using friction metal-yielding dampers, taking into acc...

In the area of semi-active control of civil structures, Magneto-Rheological (MR) damper has been an efficient mechanism for reducing the seismic response of structures. In this paper, an effective method based on defining an optimization problem for designing MR dampers has been proposed. In the proposed method, the parameters of semi-active control system are determined so that the maximum res...

The results of an extensive series of numerical simulation tests to identify the mechanical characteristics of the recently proposed roll-n-cage (RNC) isolation bearing are presented. Several different configurations of a 1/10 reduced scale prototype are included in a deep parametric study. Cyclic horizontal displacement tests considering varying test parameters of shear displacement amplitude,...

A restoring-force model is a versatile mathematical that can describe the relationship between restoring force and deformation obtained from large number of experiments. Over past few decades, body work on development models has been reported in literature. Under high intensity cyclic loadings or seismic excitations, reinforced concrete (RC) structures undergo wide range hysteretic deterioratio...

Abstract Structural damping is often empirically rate-independent wherein the dissipative part of stress depends on history deformation but not its rate change. Hysteresis models are popular for dissipation; and a hysteresis model Bouc-Wen model. If such hysteretic dissipation incorporated in refined finite element model, then involves usual structural dynamics equations along with nonlinear no...

Origins and development of 3D-BASIS (3-Dimensional BASe Isolated Structures) was initially envisioned by the need for an efficient tool for nonlinear dynamic analysis of three-dimensional base isolated structures, particularly in solving the highly nonlinear bidirectional stick-slip hysteretic response of a collection of sliding isolation bearings and the resulting response of the superstructur...

Periodic metafoundations have proven to inherit valuable properties from wave propagating in phononic periodic structures the very low-frequency regime. Therefore, finite locally resonant (LRMs) represent a novel type of seismic isolation for ultralow-frequency applications. In this context, it is still unknown impact that massive resonators with varying frequencies or devices hysteretic behavi...
