Civil Engineering

302. Elementary Structural Analysis. Reactions. Shear and bending moment. Truss stability and analysis by joints and sections. Beam deflection by moment area, elastic weight and conjugate beam. Truss deflection by virtual work Influence lines and moving loads. Analysis project. Three lectures. Fall  (Cr. 3) 

Prerequisite: ENGS 230, static equilibrium, stress and strain under axial load, beam stresses and deflections.

 

Course Goals:

  1. Analysis of statically determinate beams, frames and trusses.  Analysis of some simple indeterminate structures.

Course Outcomes:

 

The student will be able to:

  • Compute reactions for statically determinate structures.

  • Draw shear and moment diagrams for statically determinate beams and frames.

  • Verify stability of trusses.

  • Analyze trusses by joints and sections.

  • Compute beam deflections by Moment Area Method.

  • Compute beam deflections by Conjugate Beam Method.

  • Compute beam and truss deflections by Virtual Work Method.

  • Draw influence lines for statically determinate beams, girders and trusses.

  • Use influence lines to calculate reactions, shears, moments, bar forces, absolute maximum moments and shears for uniform and wheel loadings.
