Member Shies Results Access the Member Section Stresses spreadsheet by satacktng tkle Results menu and then selecting Members Stresses. These are the i-Cseeper pit .;5fi calculated along each gsela member. The number of sections for which stresses ere reported is controlled try.the Number O!Sections specified on the Glehel e•"•nitrisf The actual number of segments is this Number 01 Seism's minus 1. The incremental length of each segment is the same• For example,if you sprcaty 5 sections,the member is divided into 4 *canal pieces,and the stresses are reported for each piece, There will be four stress values listed for each section location along the member taking into account any nx r*h sc, offtiets, Tile -I units for the stresses are shown at the top o each column. As for the sign convention,t he signs of these results correspond to the signs of the farces. 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,since thr_sign CIA the stress follows the seam Of tlle'er;,;i, The sheer stress is calculated as V!5_A.,whore S A is the elective$iw r«reh For members not defined with a section set a value of 1,2 is used for the shear area coelficlent SA. The bending stresses are calculated using the familiar equation M`c/I,where'll'is the bat iuhie,icsoment,'c ix the distance from the neutral axis to the extreme fiber end T is the moment of inertia, 'the stress for the section's extreme edge is listed with respect to the positive and negative directions of the to at a esseL,:SA:e ,A tic live stress is compressive and a negative stress Is tensile, Some shapes are oat symmetrical about both local axes. For example Tee end Channel shapes. Thus the stress at the lrn ltive and negative edges may not be the clime. The locations for Ilse calculated stresses are illustrated rii this diagram; Y ,Bend Tap LBend Top x Band Bet Bend Bet Y Eland Too Bend Tops Y -Bend Bet Bend Bat So,the y-top location is the extreme fiber of the shape in the positive local y direction,ybnt is the extreme fiber in the negative local y direction.etc: The ytop,bot stresses are calculated using Ma. For enveloped results the maximum aritl minimum value at each location is listed, The load combination producing the maximum or minimum is also listed,In the Se"column. To include a particular Load Combination in the onvrlopc analysis,open the Load Combinations spreadsheet and check the box in the"Env'column. Note ' A special case is bending stress calculations for single angles. The iicndin .st,estes for koSgSs gu�lSc3 are reported for bending about the principal axes.
