The effect of axial force on the plastic bending moment resistance of class 1 or class 2 cross-sections is specified in EN1991-1-4 §6.2.9.1.

Consideration of the effect of axial force on bending moment resistance

The normalized axial force n is:
n = N_Ed / N_pl,Rd = 0.004
The ratio a is defined as: a = min[0.5, (A' - 2⋅b⋅t'f) / A' = 0.5
The reduced bending moment resistance about major axis y-y is given as:
M_y,Rd = min[M_pl,y,Rd, M_pl,y,Rd⋅(1 - [(n - a) / (1 - a)]2) ] = 160.05kNm
The reduced bending moment resistance about minor axis z-z is given as:
M_z,Rd = M_pl,z,Rd⋅(1 - [(n - a) / (1 - a)]2) = 130.075kNm
Therefore the utilization for the reduced bending resistance due to axial force is:
For bending about the major axis y-y: M_y,Ed / M_N,y,Rd = 0.12
For bending about the major axis z-z: M_z,Ed / M_N,z,Rd = 0
The effect of biaxial bending is examined in accordance with the criterion specified in EN1991-1-4 §6.2.9.1(6):
[M_y,Ed / M_N,y,Rd]α + [M_z,Ed / M_N,z,Rd]β ≤ 1
where the exponents α and β are defined as follows:
α = 1; β = 1
Therefore the utilization factor for biaxial bending including the effect of the axial force is:
Biaxial bending: u = [M_y,Ed / M_N,y,Rd]^α + [M_z,Ed / M_N,z,Rd]^β = 0.12

Result: Pass ✅

Members with laterally unrestrained compression flange subject to bending about major axis y-y should be verified against lateral-torsional buckling in accordance with EN1993-1-1 §6.3.2 as follows: My,Ed / Mb,Rd ≤ 1.0

Where Mb,Rd is the design buckling resistance moment given in EN1993-1-1 §6.3.2.1(3): Mb,Rd = χLT⋅Wy⋅fy / γM1

For class 1 or 2 cross-sections: Wy = Wpl,y = 473cm³
The reduction factor χLT due to lateral-torsional buckling is calculated for rolled sections or equivalent welded sections in accordance with EN1993-1-1 §6.3.2.3, depending on the elastic critical moment Mcr for lateral-torsional buckling.

Elastic critical moment for lateral-torsional buckling

The elastic critical moment Mcr for lateral-torsional buckling may be calculated by the following formula derived from buckling theory:
Mcr = C1⋅π2⋅E⋅Iz / (k⋅LLT)2 ⋅ ( [ (k /kw)2 ⋅ (Iw /Iz) + (k⋅LLT)2⋅G⋅IT / (π2⋅E⋅Iz) + (C2⋅zg)2]0.5 - C2⋅zg )
The factors k and kw are effective length factors. The factor k refers to end rotation on plan. It is analogous to the ratio of the buckling length to the system length for a compression member. The factor k should be taken as not less than 1.0 unless the value less than 1.0 can be justified. The factor kw refers to end warping. Unless special provision for warping fixity is made, kw should be taken as 1.0. In the following calculation the effective length factors are considered as k = 1.000 and kw = 1.000.
The distance between the point of load application and the shear center is denoted as zg. For double symmetric cross-sections the shear center coincides with the centroid of the cross-section. The value of zg is positive for loads acting towards the shear center from their point of application. For loading on the centroid the appropriate value is zg = 0.0 mm.
The coefficients C1 and C2 depend on the loading and end restraint conditions. It can be shown that the values of C1 and C2 depend on the ratio E⋅Iw / (G⋅Iw⋅LLT2). In the NCCI this ratio is considered equal to 0 which leads to conservative values for the coefficient C1 and the elastic critical moment Mcr. According to the NCCI, for uniform bending moment diagram, corresponding to no internal loading, and ratio of the end moments ψ = 1.0, the corresponding values of the coefficients are:
C1 = 1.000 and C2 = 0.000
The value of the elastic critical moment for lateral-torsional buckling is obtained as: Mcr = 0kNm
The ratio of the applied bending moment to the elastic critical buckling moment is My,Ed/Mcr = 0

Reduced bending moment resistance due to lateral-torsional buckling

The appropriate buckling curve is determined from EN1993-1-1 Table 6.5 . For rolled I-sections, h/b = 1.33, the corresponding buckling curve is curve "0".
The imperfection factor αLT corresponding to the buckling curve is determined from EN1993-1-1 Table 6.4 as αLT = 0
The non-dimensional slenderness λLT for flexural buckling is given in EN1993-1-1 §6.3.2.2(1):
λLT = (Wy⋅fy / Mcr)0.5 = 0
According to EN1993-1-1 §6.3.2.2(4) lateral-torsional buckling effects may be ignored when λLT ≤ λLT,0 or My,Ed/Mcr ≤ λ_LT,0², where λLT,0 = 0.400.
Result: 0

NRk = A⋅fy = 2453kN
My,Rk = Wy⋅fy = 160.05kN
Mz,Rk = Wz⋅fy = 130.075kN

The equivalent uniform moment factors Cmi,0 are obtained from EN1993-1-1 Table A.2.

What are steel beams used for in construction?

Steel beams are one of the most widely used elements in construction. Steel is an excellent construction material due to its well understood properties, high strength and low manufacturing cost. Steel beams and columns are used in structures for load bearing and provide a to provide a structural frame on which the building (or other structure) is constructed.

How do I design a steel beam?

Steel beams can be designed in 6 stages

Choose grade of steel, a lot of steel used today is S275 or S355.
Select a section shape classification, options include I beams, H beams, hollow sections and channels.
Decide your beam span, what is the length of the beam span?
Consider the support conditions, are the beam connections fixed, pinned, roller?
Calculate loading, there is always some form of loading acting on a beam or column.
Design, using your countries accepted codes of practice.

How to calculate a steel section classification?

Class 1 cross sections can form a plastic hinge with the rotation capacity required for plastic analysis without reducing the resistance.
Class 2 cross sections can develop their plastic moment resistance, but which have limited rotation capacity because of local buckling.
Class 3 cross sections assume the stress in the extreme compression fibre of the steel member has an elastic distribution of stresses which can reach the yield strength, but local buckling prevents development of the plastic moment resistance.
Class 4 cross sections are those in which local buckling will occur before the attainment of yield stress.
The class of the cross section can be determined from Table 5.2 of BS EN 1993-1-1, where a cross section is classified according to the highest (least favourable) class of its parts subject to compression.
