Matrix Analysis of Structures

2

Structural Analysis

• Creating mathematical models that predict

how a structure will respond to a variety of

loads.

• Models:

ƒ Simplify the structure. ƒ Retain important characteristics of the structure.

Matrix Analysis of Structures

• Primary tool for structural analysis.

• Most of the analysis is automated.

• Typically the engineer describes:

ƒ Geometry

  • member size & shape
  • member connectivity
  • support conditions ƒ Material Properties ƒ Loads 8

Matrix Analysis (cont.)

• The computer:

ƒ Formulates the governing equations ƒ Solves the equations ƒ Provides numerical and graphical results:

  • displacements
  • reactions
  • internal forces and moments

Loads and Load Arrangements

14

This Course Provides:

• Understanding of how matrix models are

formulated including:

ƒ What can be modeled ƒ What can’t be modeled ƒ How some behaviors are modeled, e.g.,

  • buckling,
  • nonlinear behavior ƒ What approximations are required for some models.

15

This Course Doesn’t Provide

  • A basic understanding of structural behavior. ƒ CE 342 – Theory of Structures is a prerequisite.
  • Information on loads and load arrangements. ƒ CE 342, plus CE 441 & CE 444 R/C and Steel Design.
  • A discussion of continuous-type structures such as: shells, plates, etc., ƒ Although they can be similarly modeled since the virtual work method we discuss leads to finite-element techniques.
