Saye Noori 10,314 اشتراک گذاری ارسال شده در 1 مرداد، ۱۳۹۲ Composite (steel_concrete) highway bridge fatigue assessment with ANSYS F.N. Leitão a, J.G.S. da Silva b,, P.C.G. da S. Vellasco b, S.A.L. de Andradeb, L.R.O. de Limab Abstract Steel and composite highway bridges are currently subjected to dynamic actions with variable magnitudes due to the action of vehicles crossing on the deck pavement. These dynamic actions can generate the nucleation of fractures or even their propagation in the structures. Depending on the magnitude and intensity, these adverse effects can compromise the structural system response and the reliability which may also lead to a reduction of the expected bridge service life. A composite (steel_concrete) bridge with a 12.50 m roadway width and 0.23 m concrete deck thickness, spanning 40.0 m by 13.5 m was investigated in this work. The computational model, developed for the composite bridge dynamic analysis, adopted the usual mesh refinement techniques present in finite element method simulations, and was implemented in the ANSYS program. ............ 3 نقل قول لینک به دیدگاه
