Flange Stress

This section is applicable for composite beams only.

SettingDescription
Precomposite Moment This is the design moment due to the loads that are applied to the bare beam prior to composite action. It only includes the Construction Dead Load. This value is listed for unshored (unpropped) beams only.
Superimposed Moment This is the design moment due to the loads applied to the beam after composite action occurs. This value is listed for unshored (unpropped) beams only.
Mpre*/Zsb This is the Precomposite moment divided by the elastic section modulus of the bare beam, Zsb. It is the steel stress caused by the precomposite moment. This value is listed for unshored (unpropped) beams only.
Msuper*/Zcb This is the Superimposed moment divided by the effective section modulus of the composite beam, Zcb. It is the steel stress caused by the superimposed moment. This value is listed for unshored (unpropped) beams only.
Unfactored Moment This is the design moment due to the total loads applied to the beam. This value is listed for shored (propped) beams only.
M*/Zcb This is the unfactored moment divided by the effective section modulus of the composite beam, Zcb. It is the steel stress caused by the total unfactored moment. This value is listed for shored (propped) beams only.
