A simply supported steel beam spans 9 m. It carries a uniformly distributed load of 10 kN/m, beam weight already included.
1. What is the maximum flexural stress (MPa) in the beam?
2. To prevent excessive deflection, the beam is propped at midspan using a pipe column. Find the resulting axial stress (MPa) in the column
3. How much is the maximum bending stress (MPa) in the propped beam?
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.
In the propped beam shown in Fig. P-844, determine the prop reaction.
Use the three-moment equation to determine the wall moment and solve for the prop reaction for the beam in Fig. P-843.
For the propped beam shown in Fig. P-842, determine the wall moment and the reaction at the prop support.
Determine the wall moment and prop reaction for the beam shown in Fig. P-841.
For the propped beam shown in Fig. P-840, determine the prop reaction and the maximum positive bending moment.
Determine the prop reaction for the beam in Fig. P-839.
If the support under the propped beam in Problem 724 settles an amount $\delta$, show that the propped reaction decreases by $3EI\delta / L^3$.
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 $R$.
