Moment Profile C_b = 12.5 M_max / [2.5 M_max + 3 M_A + 4 M_B + 3 M_C ] M_max - absolute value of maximum moment M_A - absolute value of moment at quarter point M_B - absolute value of moment at centerline M_C - absolute value of moment at three-quarter point

End Moment Coefficient C_m: 1). C_m = 0.85, for compression members in frames subject to joint translation (sideway) 2). C_m = 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 C_m = 0.85, for members whose ends are restrained C_m = 1.0, for members whose ends are un-restrained
