This paper presents an unconditionally stable integration method, which introduces a linearly implicit algorithm featuring explicit displacement expression. The technique that is being considered integrates one Newton iteration into the mean acceleration method. stability of proposed in solving equations motion containing nonlinear restoring force and damping analyzed using root locus objective...

In this paper the performance of Artificial Neural Networks (ANNs) and Adaptive Neuro- Fuzzy Inference Systems (ANFIS) in simulating the inverse dynamic behavior of Magneto- Rheological (MR) dampers is investigated. MR dampers are one of the most applicable methods in semi active control of seismic response of structures. Various mathematical models are introduced to simulate the dynamic behavi...

The nonlinear dynamic characteristic of a tubular linear eddy current damper (TLECD) and the transient responses to shock excitations single-degree-of-freedom (SDOF) system with TLECD are studied. First, force-velocity relationship is discussed using finite element simulation mathematical model fitting. Next, influences three forms excitation various mechanical parameters on vibration control a...
