ON THE BEHAVIOUR OF THE HYSTERETIC WIRE-ROPE ISOLATORS UNDER RANDOM EXCITATION
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2013, Vol 58, Issue 3
Abstract
Difficulties in characterizing of behavior of the wire-rope isolators under random excitation is the motivation for investigation of the modified Bouc-Wen model in the spirit of Baber and Noori, in order to include the experimentally observed stiffness and strength degradation, and pinching, respectively. The prediction of the behavior of such structures with hysteretic shear behavior under random excitation is investigated in this paper. The model is verified for the case of harmonic excitation with a range of exciting frequencies and amplitude levels, on the base of reported data in literature.

ON THE POST-EARTHQUAKE DAMAGE DETECTION OF STRUCTURES
The paper introduces an alternative method for evaluation the postearthquake damage in the multidegree of freedom structures with viscous and hysteretic behavior. Assuming damage as a scalar variable is very simplistic....
COMBINED XFEM-COHESIVE FINITE ELEMENT ANALYSES OF SINGLE-LAP JOINTS
Cohesive Zone Modelling (CZM) and eXtended Finite Element Modelling (XFEM) available in Abaqus® are used together to simulate the behaviour and strength of a single-lap adhesively bonded joint. A distinct CZM model is al...
TRENDS IN SURGICAL ROBOTICS
Surgical Robotics today is essentially about two families of devices, namely telemanipulators and simulators for mini-invasive (endoscopic) procedures. In both cases, the user-interface, i.e. the “joystick” to be manipul...
PROBABILISTIC SEISMIC VULNERABILITY ANALYSIS OF REINFORCED CONCRETE COLUMNS
Estimating the response of reinforced concrete columns to a transitory action, represented by a ground motion, is an uncertain task. The randomness of the seismic event and that of the response should be accounted for. T...
