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.
Figure 1 A warehouse frame system
The detailed information of the structural components is provided as follows:
Slabs 1 and 2 are made of in-situ cast reinforced concrete and have a thickness of 150 mm (Figure 2). 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 × 600 mm. Note that the density of reinforced concrete is 2500 kg/.
1. Estimate the loads applied on the Beam 1, including the load transferred from Slabs 1 and 2 (self-weight of slabs), the self-weight of Beam 1 and the water tank load. Note that the water tank load may be idealised as a point load. Please also note that there are also other types of loads, which should be considered for practical design, but for simplicity they are not considered here.
2.Consider Beam 1 is simply supported, draw the free body diagram and the shear force and bending moment diagrams.
