Calculate the safe load over a compression member of unsupported length of 4.8 m. The member is to be used in a transmission line tower and is as shown in Fig. Ex. 4.5. The ends are held in position but not restrained in direction. The overall section of the member is 180 mm x 180 mm. Assume f, = 250 N/mm2.

Frames

The trusses and frames are the two most important structural members of civil engineering. Trusses are the interconnection of links and other structural members. The interconnection with other members makes the system behave as a single member that supports and transfers loads. Trusses are generally two types, plane truss, and space truss. Frames on the other hand form the skeleton of any building construction. Frames are structures formed by the connection of beams, columns, slabs, and joists. These members provide the building with the required structural support.
