Transcript

  • 1.
    • VIII.) Deflection of Beams
    • A.) Reasons to Consider Deflections
  • 2. B.) Assumptions in Deflection Formulas 1.) Stress does not exceed Proportional Limit 2.) Beam Material is: a.) Homogeneous b.) Has Linear Stress-Strain Curve c.) Modulus of Elasticity is same in Tension and Compression 3.) Plane sections remain plane
  • 3. B.) Assumptions in Deflection Formulas 4.) Beam has a vertical plane of Symmetry and Loads and Reactions act in this plane, perpendicular to the longitudinal axis of the beam.
  • 4. B.) Assumptions in Deflection Formulas 5.) Deflections are relatively small, and the length of the elastic curve (deformed beam) is the same as the length of its horizontal projection.
  • 5. B.) Assumptions in Deflection Formulas 6.) Deflection due to shear is very small therefore negligible.
  • 6. C.) Using Diagrams & Formulas to Compute Deflections (Appendix H of Text) W = Total Load (kips,N) w = Distributed Load (kips/in,N/m) I = Moment of Inertia (in 4 ,m 4 ) l = Span Length (in,m) x = Distance from left support to location you wish to compute deflection. a & b are defined by the diagram.
