SB001 BASE STORY Castellated beam strength not satisfied.
The design strength of steel castellated beams is calculated according to the conditions specified below.
...
Axial force and biaxial bending interactionThe interaction of flexure and compression: Axial force and biaxial bending flexural strength are calculated in the solid body part gross area of the castellated beam.
Shear strength values in gross area , and net area: Shear in gross area, solid body section of the castellated beam; The shear in the net area is calculated by taking into account the hollow section of the castellated beam. Gross and net shear areas are calculated as shown below and compared with the shear force in these sections.
Horizontal shear control: The shear force on the castellated beam body is calculated using the balance equation free body diagram and compared by calculating the shear strength.
Web post buckling control: Bending moment values at the upper and lower limits of the solid core section between the castellated beam spaces are found, and lateral torsional buckling is checked according to the rectangular section.
Vierendeel bending control: The effects on the T-section on the honeycomb Castellated beam gap are found with the help of balance equationsby using the free body diagram. This control is made by calculating the interaction of flexure and compression of this the T-section under the influence of biaxial bending and axial force.

Solutions:
Vierendeel bending control
"Number of castellated filled from the beginningCas. filled hole count at the start" and "Number of castellated filled from Cas. filled hole count at the end" of the element whose name and floor are given can be increased. This technique is one of the first choice solutions for vierendeel control. This It can be done from the "General Settings" tab of the steel beam settings “Steel Beam Settings” window.
The cross-sectional dimensions of the element whose name and floor are given can be enlarged.
Axial Force and Biaxial Bending Effect
The lateral retention length bracing distance can be reduced by connecting roof braces and stability elements to the element steel beam whose name and floor are given. The bending capacity of the elements increases as the lateral retention length decreases.
The Steel element cross-sectional dimensions of the element whose name and floor are given section can be enlarged.
Slip Shear Control in Gross and Net Area
The Steel element cross-sectional dimensions of the element whose name and floor are given section can be enlarged. A cross section with a larger body area can be selected.
Horizontal cut shear control
The Steel element cross-sectional dimensions of the element whose name and floor are given section can be enlarged.
Trunk sprain Web post buckling control
The Steel element cross-sectional dimensions of the element whose name and floor are given section can be enlarged.
