CIEG 302: Structural Design
Lecture 2

STRUCTURAL ENGINEERING
ANALYSIS & DESIGN
  1. Selection of the type of structural form to be used and the material out of which the structure is to be made.
  2. Determination of the external loads that can be expected to act on the structure.
  3. Calculation of the stresses and deformations that are produced in individual members of the structure by the external loads.
  4. Determination of the size of the individual members so that the existing stresses and deformations are acceptable (i.e. satisfy the strength, fatigue, and serviceability limit states).

MATERIALS
  1. Type.
  2. Properties.
  3. Capacity.

STRUCTURAL FORMS
  1. Beams
  2. Arches
  3. Cable Supported Structures
  4. Trusses
  5. Domes & Shells
  6. Frames


    7. Photo Library

LATERAL FORCE RESISTING SYSTEMS
  1. Shear Wall.
  2. Baced Frame.
  3. Rigid Frame.
  4. Tube.

STRUCTURAL MEMBERS
  1. Tension Members
  2. Beams
  3. Columns
  4. Slabs

LOADS
  1. Type.
  2. Variability.

DESIGN CRITERIA
  1. Strength (Limit State Design).
  2. Serviceability.
  3. Fatigue.
  4. Economics.
  5. Aesthetics.

DESIGN PROCESS
(Bridge, Building, Rehabilitation, New Material)
  1. Constraints.
  2. Select form and material.
  3. Create model of structure.
  4. Determine loads and load paths.
  5. Conduct analysis.
  6. Evaluate strength, fatigue, and service limit states.
  7. Iterate to solution.
  8. Have design reviewed.
  9. Consider fabrication, constructability, inspectability, aesthetics.
