Document Summary
Indicating that the bar may yield near midspan. If we pick the bar from its center (x=ltot/2): To investigate at what values of x we may reach peak moments below the yield moment we plot mn and mp vs. x: The plot suggests that we can recommend picking the bar from points located within. 3ft from its quarter points (an instruction that may be simple to transfer to the field) and still have room for error: Nominal bending moment causing bending stresses to reach the yield stress w 490pcf ab . Define x as the distance from bar end to closer support. If we pick the bar from its ends (x = 0) Indicating that the bar is not expected to yield if picked from its ends. The same should be true if the bar is to be picked from its center:
