The h and v subscripts refer to horizontal and verti- cal moments and have been used in several Crescent City dolos references. X M = Mh\. HORIZONTAL FLUKE Figure 7. Definition sketch for principal stress computation 40. The maximum bending stress for the cross section can be found using an iterative technique by sampling the stress around the cross-section perimeter. In the prototype, axial strains were measured by summing rather than differencing the opposing strain gage bridges, but shearing strains due to flexure were not measured. 22.
