AS for the sign convention.the signs of those <br /> rewires i;orrespond to the signs of the forces. These line up as positive or negative accnrding to the member local axis <br /> dirertion5. <br /> the axial stress is the ratio P/A,where P is the section axial force A positive stress is compressive, since the sign of <br /> the stress follows the m:s.r.nr_Lr?-j'.,r<ca <br /> The shear stress Is calculated aft VJS A.whore S A is the er!eetriar ait;;jt. _ For mernberr5 not eteflnrtd with a section <br /> seta value of 12 is used for the shear area coefficient SA <br /> The bending stresses are calculated using the!Aguilar equation M•c/I,where'll'is the helloing rrusmnnt,'c'is the <br /> distance(Ron the neutral axis to the extreme fiber and 1'is the mument of inertia The stress for the elicitor's extreme <br /> edge is listed with respect to the positive aril negative directions of the Jocai`'_S„'.I,1 l5t.} A.positive stress is <br /> compressive and a negative stress is tensile <br /> Some shapes are riot symmetrical about both local axes. For example Tee and Channel shapes Thus llie stress at the <br /> Mr5itive and negative edges may not be the same.
