The rectangular section is $10$m in diameter of a single reinforced concrete simple beam. Suppose that concrete using general aggregate was used, the design standard compression strength was $28$ MPa, and the yield strength of the shear reinforcement used was $300$ MPa. When calculating the weight of a single reinforcement beam, apply the concrete unit weight to $25$ kN $/$ m $^2.$ An additional load WSD of $5$ kN $/$ m $^2$ operates from $2$ m away from the point to $6$ m$,$ and an active load WL of $4$ kN $/$ m $^2$ acts in the entire section. Use $1\mathrm{.}2$ for the fixed load and additional load, $1\mathrm{.}6$ for the load and $1\mathrm{.}6$ for the load to determine the shear force line acting on this simple beam and the shear bar placement section. The width of the rectangular beam is $500$ mm$,$ the height is $700$ mm$,$ and the effective depth of the tensile reinforcement is $600$ mm$.$ Suppose the diameter of the shear reinforcement used is D$10.$ Calculate and diagrammatically place the shear stirrup spacing between the shear reinforcement placement sections. Place the first shear stirrup $100$ mm away from the end of the beam.
