Moment Profile C b = 12.5 Mmax / [2.5 Mmax + 3 MA + 4 MB + 3 MC ] Mmax - absolute value of maximum moment MA - absolute value of moment at quarter point MB - absolute value of moment at centerline MC - absolute value of moment at three-quarter point
End Moment Coefficient C m: 1). Cm = 0.85, for compression members in frames subject to joint translation (sideway) 2). Cm = 0.6 - 0.4 (M1 / M2) , for restrained compression members in frames braced against joint translation, not subject to transverse loading. M1 - the smaller moment, M1 / M2 is positive when the member is bent in reverse curvature 3). For compression members in frames braced against joint translation, and subject to transverse loading Cm = 0.85, for members whose ends are restrained Cm = 1.0, for members whose ends are un-restrained
