Abstract This paper investigated the nonlinear seismic performance of an existing cable-stayed bridge longitudinally subjected to a set simulated near-fault ground motion pulses. An elaborated non-linear finite element model was established which particularly considered cable sag effect, material nonlinearity tower and deck. Through dynamic response analyses, responses tower, deck cables were e...

in this paper robust pid control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. in dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. to develop the idea of control for cable robots with elastic cables, a robust pid control for cable driven robots with ideal rigid cables is firstly de...

• Large vibration amplitudes of the stay cables Stavanger City Bridge (Norway) were occasionally reported. A monitoring system including accelerometers, an anemometers and a field camera was deployed. Rainfall found to promote onset large amplitude heave oscillations. The range mean wind speed values, reduced velocities wind-cable angles associated with rain-wind-induced vibrations characterise...

Introduction. The historic cable-stayed suspension bridge of the city Deir ez-Zor in Syria, which is an architectural monument, described. history its creation at beginning twentieth century and destruction during hostilities 2013 given. importance this for country as a whole indicated, was reason choice object research. Aim. study intended to contribute restoration (or) subsequent seismic stre...

We investigate the nonlinear random vibration of the cables with small sag and excited by colored or filtered Gaussian white noise uniformly distributed on the cable. The cable and many other systems in science and engineering can be modeled as nonlinear stochastic dynamical (NSD) systems with multiple degrees of freedom (MDOF). It is known that the analysis on the probabilistic solutions of MD...
