A steel strut of rectangular cross-section is 3m long. The depth of the section is twice the width of  the section. If the strut has one end fixed and the other end pinned, and a Rankine’s constant of  1⁄45000, calculate the sectional dimensions of the strut using the Rankine formula. The allowable  stress is 200 MPa and the maximum load is 120 kN

Braced cuts

The braced cut is a method of providing lateral support to the soil in foundation trenches, to prevent the trenches from deformation by the caving in of soil and resisting it from moving laterally. During shallow excavation in firm soil, generally, slopes are provided to resist the caving in of soil. During shallow excavation in soft soil and deep excavation, the chances of caving in of soil increase. Hence, it becomes necessary to make a provision to resist the deformation of trenches due to caving in of soil. The braced cut is the method used for such conditions. The excavation using braced cuts is a bit uneconomical as compared to the traditional open-cut excavation method but provides better safety than the cut excavation method.
