Abstract

The aim is to implement a computational project-based learning methodology in engineering courses that can contribute to the success and improvement of students in engineering and engineering technology programs. This learning methodology is based on both computational and programming process that can enhance student’s mathematical understanding, critical thinking, and problem solving skills through the core engineering courses.
A computational project based on both closed-form and numerical techniques with MATLAB programming will be implemented to study an impulsive response of a frame structure. The closed-form response of such system can be evaluated through convolution integral. For the case that a structure is subjected to an irregular impulsive forcing function such as seismic vibration, the numerical integration can be implemented with MATLAB programming to determine the impulsive response of such system.
In this investigation we will analyze the system response through a finite difference numerical technique. The technique can be implemented to investigate the impulsive response for both undamped and damped system with much less complex mathematical involvement. A MATLAB script based on finite difference technique can be developed to generate numerical results of such excitation during and after acting impulsive force.
