Problem 715 | Distributed loads placed symmetrically over fully restrained beam Jhun Vert Fri, 04/24/2020 - 05:00 pm

Problem 715
Determine the moment and maximum EIδ for the restrained beam shown in Fig. P-715. (Hint: Let the redundants be the shear and moment at the midspan. Also note that the midspan shear is zero.)

Problem 708
Two identical cantilever beams in contact at their ends support a distributed load over one of them as shown in Fig. P-708. Determine the restraining moment at each wall.
 

Two cantilever beams.

 

Application of Double Integration and Superposition Methods to Restrained Beams

Superposition Method

There are 12 cases listed in the method of superposition for beam deflection.

  • Cantilever beam with...
    1. concentrated load at the free end.
    2. concentrated load anywhere on the beam.
    3. uniform load over the entire span.
    4. triangular load with zero at the free end
    5. moment load at the free end.
  • Simply supported beam with...
    1. concentrated load at the midspan.
    2. concentrated load anywhere on the beam span.
    3. uniform load over the entire span.
    4. triangular load which is zero at one end and full at the other end.
    5. triangular load with zero at both ends and full at the midspan.
    6. moment load at the right support.
    7. moment load at the left support.
