WEB BUCKLING TESTS ON WELDED PLATE GIRDERS. PART 3: TESTS ON PLATE GIRDERS SUBJECTED TO SHEAR

It has been pointed out that the postbuckling strength of plate girders subjected to bending is essentially provided by the compression flange. For girders subjected primarily to shear, the flange plates cannot increase the shear resistance to any degree and, therefore, the above conclusion cannot be made. Still, a rearrangement of stresses favorable for the web is possible which might utilize an element other than the web. Most likely, the element of paramount importance in the shear case is the transverse stiffener upon which a tension field might be supported. The advancement of tension field action as an explanation for the postbuckling strength of plate girders is not a new idea. It originates from the design of lattice trusses which preceded the use of plate girders. The objective of this experimental investigation is to prove or disprove the occurrence of a tension field action in welded plate girders as used in the Civil Engineering profession.
