CE 381P - Computer Methods in Structural Analysis
Course Purpose:
CE 381P focuses on computing the response of structural frames and trusses. This class will extend many of the concepts treated in courses on matrix methods of analysis by developing a general framework for analyzing complicated structural systems. A large portion of the course will focus on computing the response of structures accounting for geometric and material nonlinearity.
Course Objectives:
By the end of the course, you should be able to do the following:
Derive stiffness/flexibility
relations for structural members using virtual work principles.
Use and/or develop structural
analysis software to analyze complicated structural systems. S Interpret the output
from computer-based analyses for the purpose of structural design.
Determine the critical load of structural systems.
Compute the load-deformation behavior of a structure accounting for nonlinear
effects.
