Shear-bending cyclic loading tests of shear-yield-precedence beam

—Bending-Shear Behavior of shear-yield-precedence short-span beam—

Abstract

Shear-bending cyclic loading tests were performed to investigate structural behavior of shear-yield-precedence short-span beam. Main test parameters are the following: beam-end connection detail (only welded or both welded and bolted connection), design principle (designed only for bending or for bending and shear), and beam web detail (stiffened by web stiffeners or with reinforced web openings). Beam-end weld connections do not fracture in the all specimens, and the all test specimens showed good plastic deformation capacity because shear yielding of the web occurred prior to shear buckling; all the test results support feasibility of shear-yield-precedence design of short-span beam.
