The design Design strength control check of the steel beam named PL019 is made done under the most unfavorable internal forces as a result of the general analysis determined according to TBDY 2018 9.3.1.4. The material and section information of the beam is as follows:
...
It should be checked whether the header flange width/thickness and body web height/thickness values of the beam cross-section exceed the λhd λhd value given in Table 9.3 .
...
The control of the cross-section conditions is made done according to the TBDY 2018 Table 9.3 in the steel beam report and is summarized in tabular form.
...
The longest unsupported beam segment in the lateral direction is Lb = 2.0 m. According to TBDY 2018 9.2.8.1(a), the distance between the points where the lower and upper ends of the special beams with high ductility level are supported, Lb should meet the following condition.
...
It provides the condition. In the steel beam report, the control results are given in tables.

Flexural Moment Strength
While checking the beam design bending flexural moment strength, since the lateral retained supported lengths are different, station-by-station should be done for each section. For the convenience of manual calculationcheck, it will be made done for the section Lb = 0.75 m, which is exposed to the most unfavorable bending flexural moment.
...
Because of the condition, the characteristic bending of flexural moment strength is calculated determined according to the yield limit condition. According to the CYTHYE equation 9.2, the calculation check is done as follows:
...
As a result of the analysis, the required bending flexural moment strength obtained as a result of 1.2G+Q-Ex-0.3Ey+0.2S+0.3Ez loading is Mu = 203.637 kNm.

Strength of The Beam
According to ÇYTHYE 10.2.1(a) in I-cross section with double symmetry axes,
...
With the load combination Q-Ex-0.3ey + 1.2G + 0.2S + 0.3ez shear loading required combination of , required shear force is determined as Vu = is determined as 12818 kN. It has been shown above that the cross-sectional capacity is sufficient.
