Member Stress Results Access the Member Section Stresses spreadsheet by seiechng the Results menu and men selecting Members Stresses. These are llie -i. ',t! - -]icirated a'nng each dl.:7.::member Tie number of sections tar which stresses are reported is centnzl;rrd by in!'Nurnhrr 01 Sections specif;ed on the Gt:-h,-;t cat_ The actual number of segments rS this Number 01 Sections minus 1 Inc incremental length of each segment is the same. For example,if yr:n Ntectly ti ceclinrir.,the member Is divided into 4 equal pieces.and the stresses are reported for each piece. There will be taro stress values listen for each section location along the nie-Phcr taking into account any r•,ci 1i)cr ':rt,,r-t•; the 1..t.,t for Ole stresses aft shuwl i at the top at each column. As tor the sign convention,the signs or these results correspond to the signs of the forces. These line up as positive or negative according to the member local axis directions. The axial stress is the ratio PIA.where P is the section axial force A positive stress is compressive, suu:e the sign el the stress fellows the t>.kr.or the.r,;- The shear stress is calculated as V!S A.whore S A is the elective:sitar;;20. For members not etetlned with a section sat a value of 1.2 is used for the shear area coefficient SA The bending stresses are calculated using the'amnia(equation M'c/I.where'll is Iha bending moment,'c'is the distance from the neutral axis to the extreme fiber and't'is the moment of inertia The stress for the auction's extreme wive ii:listed with respect to the aasitive arse negative directions of the leca! r-2 t r _,,i,.;A positive stress is compressive and a negative stress is tensile Some shapes are not symmetrical about both local axes. For example Tee and Channel shapes Thus the stress at the pn..itive and nreativr esteem may not be the same The locations far the calculated stresses are illustrated in this diagram.
