## Problem 870 | Beam Deflection by Three-Moment Equation

Problem 870
Compute the value of EIδ at the overhanging end of the beam in Figure P-870 if it is known that the wall moment is +1.1 kN·m. ## Problem 843 | Continuous Beams with Fixed Ends

Problem 843
Use the three-moment equation to determine the wall moment and solve for the prop reaction for the beam in Fig. P-843. ## Problem 842 | Continuous Beams with Fixed Ends

Problem 842
For the propped beam shown in Fig. P-842, determine the wall moment and the reaction at the prop support. ## Problem 840 | Continuous Beams with Fixed Ends

Problem 840
For the propped beam shown in Fig. P-840, determine the prop reaction and the maximum positive bending moment. ## Continuous Beams with Fixed Ends

Assume the fixed end to be equivalent to an imaginary span with imaginary loading. In three-moment equation, all the terms that refer to the imaginary span have zero values.

In the following problems, the ends of the beams are assumed to be perfectly fixed by the walls against rotation. All supports are assumed to remain at the same level.

## Problem 725 | Propped beam with partially restrained wall and settling simple support

Problem 725
If the support under the propped beam in Problem 724 settles an amount $\delta$, show that the propped reaction decreases by $3EI\delta / L^3$.

## Problem 724 | Propped beam with partially restrained wall support

Problem 724
The beam shown in Fig. P-724 is only partially restrained at the wall so that, after the uniformly distributed load is applied, the slope at the wall is $w_oL^3 / 48EI$ upward to the right. If the supports remain at the same level, determine $R$. ## Problem 723 | Propped beam with uniform load over half the span

Problem 723
Find the reaction R and the moment at the wall for the propped beam shown in Fig. P-723.
