Question

A simply supported RCC beam of span 4 m is supporting a brick wall over its entire span. The brick wall is 250 mm thick and 2 m high. The RCC beam has a depth of 600 mm and width of 250 mm. The density of brick masonry and RCC can be assumed as \(18 \, \text{kN/m}^3\) and \(25 \, \text{kN/m}^3\) respectively. Considering the load of the wall and self-weight of the RCC beam, the maximum bending moment in the beam (in kN-m) will be ......... [rounded off to two decimal places]. \begin{center} \includegraphics[width=0.5\textwidth]{08.jpeg} \end{center}

Hint:

For maximum bending moment of a simply supported beam with UDL, always use \(M = \frac{wL^2}{8}\). Carefully convert thickness and depth into meters, and use densities in \(\text{kN/m}^3\) for uniform load calculations.
