Service load effective compression flange width in fiber reinforced polymer deck systems acting compositely with steel stringers
This paper reports on the field study of a steel stringer-fiber reinforced polymer (FRP) deck composite bridge in Pennsylvania. The objective of the study is to assess the effective compression flange width in the FRP deck and floor systems when they act compositely with underlying steel girders at service conditions. The American steel building and bridge specification provisions for effective compression flange width calculations is prescribed for the case of concrete decks and slabs on steel girders acting compositely at ultimate capacity. Neither specification currently provides guidance as to the effetive widths that ought to be used in composite designs that employ fiber reinforced polymer decks and floors. The present paper will provide recommendations for FRP effective widths useful in the design of fully composite FRP-steel girder installations in the service load condition. The recommendations are for the service condition and are based on field data obtained from load testing of a composite steel stringer bridge that employed a FRP deck system. The research results support the notion of employing a design approach for FRP composite systems that is consistent with current practice related to steel girders acting compositely with concrete decking. Based on the current results it is observed that FRP decks and floors exhibit an effective width of approximately 75 % of the girder spacing for interior girder installations and 90 % of the total distance, for the case of exterior girders.
