T-Beam width

Beam is the plate value. It is the beam width value in rectangular sections. (b)

In symmetrical sections;
b = bw + 1/5 lp

For unsymmetrical sections,
b = b1 + 1/10 lp
lp = a ln

For a, the following values ​​can be used:
Single span simply supported beams a = 1
Continuous beams (side span) a = 0.8
Continuous beams (center span) a = 0.6 For
cantilever beams a = 1.5

Upper limits
b <= bw + 12 hf (symmetrical section)
b <= £ b1 + 6 hf (asymmetric section)

or
b <= bw + ½ an (symmetrical section)
b <= b1 + ½ an (asymmetric section)

ln

It is the net span value of the beam from inside the column to the inside of the column, from the beam edge to the beam edge if the beam is supported to another beam.

Design shear force

It is the design shear force used in stirrup calculation.  

In beams of high ductility level;
Ve = Vdy ± (Mpi + Mpj) / ln
Vd: It is the shear force calculated under the combined effect of the vertical loads and earthquake multiplied by the load coefficients.
Mpi, Mpj: The left and right end are moments of carrying power. In beams of normal ductility level;
Vd value is taken directly as Ve.

Vcr

It is the shear force that creates the oblique crack.
Vcr: 0.65 fctd bw d

Vc

It is the shear force carried by concrete.
And if - Vdy> = 0.5 Vd then Vc = 0 is taken.
Otherwise, Vc = 0.8 Vcr is calculated.
Vd: It is the calculated shear force under the combined effect of vertical loads and earthquake loads multiplied by load factors.

Vr

It is the maximum cutting force value that the section can carry. The design shear force Ve used in stirrup calculation is not allowed to exceed Vr.

The method followed in the calculation of Vr:
Vw: It is the contribution of shear reinforcement to the shear strength.
Vw = (Asw / s) * fywd * d
Vr = Vc + Vw The
contribution of the battery to the shear force is never included in the shear calculation.

Vmax

It is the maximum shear force that the section can carry.
Vmax = 0.22 fcd bw d
Ve <= Vmax or Ve <= Vr otherwise the section is insufficient. The program will then warn of insufficient section for the beam in question.

TS500 vd

Design shear force determined according to TS500.

TS500 vMax

Maximum shear force that the section can carry, determined according to TS500.

asw/s

asw / s

It is the area of ​​1 meter of single arm stirrup found for densification zone as a result of shear force calculation. And it is calculated.

And = Vdy ± (Mpi + Mpj) / ln

If And> Vmax or Ve> Vr, the cross section is insufficient.

And Asw / s is calculated from the formula of = (Asw / s) * fywd * d + 0.8 Vc. S is accepted as 1 meter.

 And if - Vdy> = 0.5 Vd then Vc = 0 is taken.

The asw / s value is never allowed to be less than 0.3 (fctd / fywd) * bw.

Reinforcement

It is the stirrup rebar selected from the Asw / s value. It is shown as the number of stirrups, the diameter of the rebar, the middle and the spacing in the densification region, respectively.

Diagonal reinforcement

Lists the control information in table form of the diagonal rebar design related information in the tie beams. (TBDY Article 7.6.8)

Ln> 2hk and V <= 1.5 bw d fcd checks are made.

Asd = Vd / (2fydsin (y))

ln: Beam clear span
hk: Beam height
Vd: Shear force calculated under the combined effect of vertical loads and earthquake loads multiplied by load factors
