What is the reinforced concrete deep beam and where it used?
What is the required number of bars and it’s diameter in column for 5 storey building.
First of all you have to design that story building to provide reinforcement for all members such as slab ,beam,etc. by using different code such as IS etc.

Torsion is the twisting of a beam under the action of a torque (twisting moment). It is systematically applied to screws, nuts, axles, drive shafts etc, and is also generated more randomly under service conditions in car bodies, boat hulls, aircraft fuselages, bridges, springs and many other structuRead more
Torsion is the twisting of a beam under the action of a torque (twisting moment). It is systematically applied to screws, nuts, axles, drive shafts etc, and is also generated more randomly under service conditions in car bodies, boat hulls, aircraft fuselages, bridges, springs and many other structures and components. A torque, T , has the same units (N m) as a bending moment, M . Both are the product of a force and a distance. In the case of a torque, the force is tangential and the distance is the radial distance between this tangent and the axis of rotation.
All torsion problems can be solved using the following formula:
T/J = shear stress/ r = (G * angle)/ L
where:
T = torque or twisting moment, [N×m, lb×in]
J = polar moment of inertia or polar second moment of area about shaft axis, [m4, in4]
τ = shear stress at outer fibre, [Pa, psi]
r = radius of the shaft, [m, in]
G = modulus of rigidity (PanGlobal and Reed’s) or shear modulus (everybody else), [Pa, psi]
θ = angle of twist, [rad]
L = length of the shaft, [m, in]
How to calculate stiffness of storey to avoid soft storey of multi-storeyed building?
Avoid soft storey? A soft storey is a storey with lateral stiffness less than the storey just above. So technically, you cannot avoid soft storey just by calculation. Right? Well, according to the new code for seismic design, IS 1893 Part I (2016), infill masonry walls in soft storeys of RC buildingRead more

Well, according to the new code for seismic design, IS 1893 Part I (2016), infill masonry walls in soft storeys of RC buildings can be modeled as diagonal struts to contribute to lateral stiffness.Though this doesn’t guarantee that the resulting storey stiffness with the contribution of infill walls, will be greater than that of the storey above.
Method :
[Note : Even after reading the answer please do refer to table 6, fig. 4 and section 7.9 of IS 1893 Part I (2016) for two formulae mentioned above and a clearer understanding of the method in detail.]

You can’t build a column on slab unless slab is designed for the load you needed for. It is regarded as pt load on slab which is usually not designed for it, it all relies on what purpose you want to raise the column on slab.
Why we provide Anchor Bar in a single RC beam?
Anchor bars are the bars which are given on compression side to hold the stirrups or lateral reinforcements and the main bars.
