A Finite Element Model for the Analysis of Bridge Decks
The analysis of bridge decks is at present effected using mostly the method of distribution coefficients. The method involves the use of coefficients obtained from charts for the approximate determination of bending moments in simply supported right concrete bridge decks. However, the method is limited to only simply supported decks. Also, reading the charts and interpolating between curves can be very tiresome and can easily introduce errors in the analysis. This paper therefore proposes and develops a finite element model as a more versatile alternative for the analysis of bridge decks for all support conditions. The results show that the proposed model is sufficiently accurate compared to solutions obtained using the method of distribution coefficients.
