Abstract

The Lazer – McKenna mathematical model of a suspension bridge applied to the Adomi Bridge in Ghana is presented. Numerical methods accessible in commercially available Computer Algebraic System “MATLAB” are used to analyze the second order non-linear ordinary differential equation. Simulations are performed using an efficient SIMULINK scheme, the bridge responses are investigated by varying the various parameters of the bridge. 

Keywords: Adomi Bridge, Suspension bridge, Matlab simulations, Mathematical model, Runge Kutta Method.
