A horizontal beam AB is pin-supported at the end A and carries a uniformly distributed load with intensity 20 kN/m and a concentrated load F as shown in the figure. The beam is also supported at C by a pinned-end column: the column is restrained laterally at mid-height in the plane of the figure but it is free to deflect perpendicular to the plane of the figure. Assume the column may buckle in any direction. The column is a solid...
A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q= 30 kN/m (see figure)
A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q= 30 kN/m (see figure). The beam is constructed of a wood member, 100 mm wide by 150 mm deep, and is reinforced on its lower side by a steel plate 8 mm thick and 100 mm wide.
