The sign convention for shear is positive when the free body diagram causes the member to spin clockwise (with I End on the left and J End on the right). ForĪxial forces, compression is positive. As can be seen, the sectionįorces listed at any given section are the left side forces. Location with all positive section forces. These are axial, shear parallel to the local y axis (Shear y-y), shear parallel to the local z axis (Shear z-z), torque moment, momentĪbout the member's local y axis (Moment y-y) and moment about the member's local z axis (Moment The left side forces at each section location The signs of these results correspond to the member's local axes, using This may not be useful for continuous members or cantilever members where the i-end and j-end may not be at a support.Īt the top of each column. The End Reactions Tab shows the member forces at the ends of the member. Because the Number of Internal Sections is typically much larger than the Number of Reported Sections, this means that the Maximums Tab will always display the highest/lowest force in the member whereas the Sections Tab will miss the highest/lowest force under all but the most simple load diagrams. The Maximums Tab shows the maximum force that occurred in the member based on the Number of Internal Sections. The Number Of Reported Sections specified in the Model Settings Dialog. The number of sections for which forces are reported is controlled by Spreadsheet by going to the Results Menu and then selecting Member Forces then clicking the Sections tab.Īlong each active member taking into account any member offsets. To see more results on screen while printing only the end forces. Is the equivalent to setting the Number of Reported Sections to '2' but allows you There is a printing option for end forces that Of Reported Sections to '2' will only report end forces which, might be desirableįor connection calculation but not when looking for maximum forces alongĪ members length. Of the member, which is often the location of maximum moment. Of Reported Sections to an even number will not report forces /stresses at the midpoint With odd numbers for the Number of Reported Sections.
