A section damage model is given based on damage constitutive relation of compression concrete and damage parameters is studied for L-shaped cross-section under biaxial bending with orthographic design method in order to select sensitivity factors. The research result indicates that the flange-thick ratio is the most important factor for the cross-section bearing capacity, the next is steel ratio and loading angle, which is a very important factor due to its asymmetry. Study also found out that steel ratio can reduce section damage, next is concrete strength, last one is loading angle which can aggravate section damage.
