Beam Shear and Capacity Calculation

[qwerty]

In order to be able to interpret and understand the reinforced concrete part of the beam better and thus design the construction safely and economically, In a highly ductile structure, reinforcement due to the bending moment in the reinforced concrete part of the beam, shear calculations, etc. Can you share an example calculation explaining it? For example, how does he calculate Vd (over the axis, on the column face, is it at a distance d from the column?) If the beam - beam - column is supported, how does he calculate Vd (over the axis, the face of the column, is it at a distance d from the column?) Can you answer?

In order to better interpret and understand the beam reinforced concrete part, so that I can design the construction safely and economically, can you share if there is an example calculation explaining the reinforcement, shear calculations etc. due to bending moment in the beam reinforced concrete part in a highly ductile structure? For example, how does it calculate Vd (over the axis, the column face, is it at a distance d from the column?) If the beam - beam - column is supported, how does it calculate Vd (Is it on the axis, the column face, is it d distance from the column?) Can you answer?

Ductility In beams with high level, Ve= Vd ± ( Mpi + Mpj ) / ln Ve design shear force Vd= Vertical loads multiplied by load coefficients and shear force calculated under the combined effect of earthquake Mpi, Mpj = Left and right end bearing moments Ln= The beam is the clear span (measured distance from the inside of the column to the inside of the column) In normal beams of ductility, and beam-beam junctions, the design shear force Ve is Vd . The above formula does not apply. Vmax is the maximum shear force that the section can carry. Vmax= 0.22 fcd bw d Ve must be <= Vmax or Ve<=Vr, otherwise the section is insufficient. In this case, the program will give an insufficient section warning for the beam in question. bw=beam width, d beam height fcd=concrete compressive strength Vcr Shear force forming oblique cracking. Vcr=0.65 fctd bw d fctd=concrete tensile strength Vc is the shear force carried by the concrete. And - Vd >= 0.5 Vd, then Vc=0. Otherwise, Vc= 0.8 Vcr is calculated. Vdy=It is the shear force calculated under the combined effect of the vertical loads multiplied by the load coefficients and the earthquake loads. Vr is the maximum shear force value that the section can carry. The design shear force Ve used in stirrup calculation is not allowed to exceed Vr. The path followed in the calculation of Vr: Vw= Contribution of shear reinforcement to shear strength. Vw= (Asw/s) * fywd * d Vr= Vc + Vw. The contribution of the pile to the cutting force is never included in the cutting calculation. Reinforcement and moment capacities of reinforced concrete elements are calculated according to the bearing capacity method. You can find these calculations in any reinforced concrete book.
