In order to determine the maximum bending stress in steel H-beams, several factors must be taken into account.
Firstly, the maximum bending moment that the H-beam will experience needs to be determined. This can be achieved by analyzing the applied loads on the beam, including dead loads (the weight of the structure itself) and live loads (any additional weight placed on the beam). By calculating the reactions at the supports and summing the moments at any given section of the beam, the maximum bending moment can be established.
Next, it is necessary to calculate the section modulus of the H-beam. The section modulus is a geometric property of the beam's cross-section, indicating its resistance to bending. This can be calculated by dividing the moment of inertia of the cross-section by the distance from the centroid of the cross-section to the extreme fiber. The moment of inertia can be found in standard engineering references or by using software programs.
Finally, the maximum bending stress can be calculated utilizing the formula σ = M / S, where σ represents the maximum bending stress, M is the maximum bending moment, and S is the section modulus. This formula establishes the relationship between the applied moment and the stress induced in the beam.
It is important to emphasize that accurate input data, including correct values for loads, beam dimensions, and material properties, are crucial for calculating the maximum bending stress in steel H-beams. Moreover, it is advisable to consult the applicable design code or standard for any specific requirements or factors that need to be considered.

To calculate the maximum bending stress in steel H-beams, you need to determine the moment of inertia of the cross-section and the applied bending moment. The bending stress can then be calculated using the formula: stress = (bending moment * distance from neutral axis) / (moment of inertia * section modulus).
