Webbending is not easily defined. Consequently, engineers choose to draw the bending moments on either the tension (common amongst structural engineers) or compression side of the members. They are not labeled as either positive or negative. Alternatively, a vector sign convention can be used– usual for computer codes. 28 Example Frame Problem 1 WebThe maximum shear stress in an axially loaded bar is only one-half the maximum normal stress.
