Reliability analysis of suspension bridges against buffeting failure
A reliability analysis of suspension bridges against buffeting failure due to gustiness of wind velocity is carried out using the concept of PRA (probabilistic risk analysis) procedure. For this purpose, the bending stresses at the critical nodes of the bridge deck are obtained for buffeting forces using a spectral analysis technique and a finite element approach. For the purpose of reliability...
متن کاملComparative Numerical Analysis of RCC Roof Models
A wide spectrum of eco-friendly and innovative building systems is being introduced in the building sector as a consequence of environmental concern. The key to maintaining a comfortable temperature in a building is to reduce the heat transfer out of the building in the winter and reduce heat transfer into the building in the summer. Roofs are construction elements that close the building at th...

15 صفحه اولNumerical and Experimental Analysis of Nonlinear Parabolic Springs Employed in Suspension System of freight cars
Nonlinear vibration of parabolic springs employed in suspension system of a freight car has been studied in this paper. First, dynamical behavior of the springs is investigated by using finite element method and the obtained results are then used in vibration analysis of a railway freight car. For this purpose, dynamics of a parabolic spring subjected to a cyclic excitation has been studied ...
