FACTORED MOMENT RESISTANCE OF COMPOSITE BRIDGE GIRDERS WITH SINGLY SYMMETRICAL NONCOMPACT STEEL SECTIONS

According to standards CAN/CSA-S6-88 and OHBDC (1983), a fully plastic stress distribution or a linear stress distribution at first yielding of the steel section should be used to determine the factored bending resistance of a composite section made of a non-compact steel section , depending upon the depth of the compression portion of the web. In t his paper, an elastoplastic analysis is presented and is illustrated b y an example. Comments on some clauses from the S6 Standard are also p resented.
