FRP Stay-in-Place Structural Forms for Concrete Bridge Decks: A State-of-the-Art Review

Abstract. The subject of this analysis is connected with the verification of the load capacity of the span structure taking into account the degree of corrosion of the railway viaduct components located at 41.446 km, on the railway line no. 301 of "Kotlarnia" SA Sand Mine built over the national road DK88 and railway tracks PKP-PLK near T. Kościuszki street in Zabrze The general condition of the structure with regard to the corrosion assessment of structural steel is presented in the paper. Static and strength calculations were carried out to determine the load capacity class, and as a result of the analysis it was found that the technical condition of the facility steel girders is suitable for repair. General description of the facilityThe railway viaduct runs a single-track railway line over the national road No. 88 and railway tracks of PKP-PLK. The tracks on the object are placed in a horizontal curve. The building consists of two spans in a mixed-wall full-blown steel structure -riveted and welded with the bridge open on bridge sleepers. In the cross-section, two main girders with intermediate steel plates were used. The railway line crosses the road diagonally. Supports parallel to the obstacle were used -the object is diagonal. In order to complete the object and level the bevel, additional short spans were used perpendicularly to the axis of the abutment track. The girders were built in kinked curve shape adapt to the pillar track arc. The northern span of the riveted structure has a theoretical span of 28.40 m, plus a support with a projection of 3.90 m, on which the welded structure of the southern span is based. The theoretical span of the eastern span is 19.50 m, and the western span is 19.90 m. On the bridgehead, on the western beam, a short span is used to level the structure bevel. The bridge supports [13,19] consist of two bridgeheads and a pillar with a circular, massive concrete structure. At the western girders, the sidewalk is made on the outside on brackets attached to the girder. Figures 1 ÷ 3 describe the analyzed object.

“…This type of formwork is permanently installed and after the concrete work is an indispensable part of the object. During implementation, the SIP formwork acts as a forming and supporting element, while during operation -a construction, insulation (including insulation against corrosion) or construction-insulation element [5][6][7][8].…”

Formworks are an inseparable element of the building and engineering structures shaping, which are implemented in technology of the monolithic concrete. This article attempts to collect information related to construction and material, as well as utility conditions which formworks should meet. Particular attention was paid to issues related to the use of SIP (stay-in-place) formwork systems. General requirements and functions that should be met by formworks (especially SIP formworks) are discussed, with an indication of loads acting on those formworks. In addition, the scope of control carried out as part of the execution supervision of formworks was analyzed and necessary actions to be taken in the event of a detected non-compliance were presented.
