Calculate the normal stress and shear stress acting on an element G, 150 mm from the top surface of the beam, in the section G to the left of the point load Fwt (water tank load) as shown in the bottom figure and then determine the principal planes and the principal stresses. Fwt A >> G E 8 Beam 1 B DESIGN DESCRIPTION To construct a warehouse, the frame system shown in Figure 1 has been adopted. As an engineer, your task is to analyse the mid frame, highlighted in RED.

For simplicity, we assume that half the weight of each slab is transferred to Beam 1 (as shown in Figure 2). In addition, a water tank full of water with a weight of 1042 kg (1000 L of water plus weight of the tank) will be installed in the middle of Beam 1 (Figure 2). All the beams are made of reinforced concrete and have a standard size of 225 mm x 600 mm. Note that the density of reinforced concrete is 2500 kg/m³.
