Abstract: The use of post-tensioning to increase the strength of steel beams in beam and concrete-slab bridges is shown to be feasible. The purpose of the study is to determine a technique for increasing the capacity of the bridges to meet today's loadings. The results of testing a half-scale model of an existing bridge indicate that post-tensioning can be used with only minor deck cracking. Comparisons of the data from the model with results using orthotropic plate theory indicate that this theory can be used as a preliminary design methodology for determining the required prestress force and its location for strengthening existing bridges.

Abstract: A pressing assembly for ham moulds etc. The assembly comprises a flat supporting deck to carry several rows of equally spaced moulds. Each mould base can transmit pressure to the cover of a mould on a similar lower deck via a hole through the deck. As relative vertical movements between a mould and its supporting deck takes place, a vertical guide restricts any sideways movement. Pref. each mould has at least one vertical leg fixed on the underside of the mould base. The leg extends through the hole in the deck and has its lower end fixed to the cover of a mould on the deck below. In this case the leg serves as the vertical guide and sideways movement is restricted by the interior surface of the hole. Each deck pref. has downwardly turned side flanges which have a vertical length greater than that of the leg plus the attached mould cover, i.e. if the assembly is placed ina flat surface each mould rests on the deck with the attached cover suspended clear of the flat surface. A considerable number of moulds can be handled simultaneously throughout a number of operations e.g. moulding, pressing, cooking, demoulding.

Abstract: A belt, band or other tire component folding machine and method are characterized by a rotatable and expandable drum comprising a substantially rigid cylindrical deck having a precisely formed peripheral deck edge and an inflatable bladder assembly positioned slightly axially and radially inwardly subjacent the deck edge which cooperate to define a precise fold line along the deck edge at which a ply or belt band or the like is precisely and sharply folded. Preferably, dual inflatable bladders are employed at each end of the deck, one bladder being contiguous to the other and arranged on inflation to walk up the precisely formed and contoured deck edge to turn up the overhanging band end, and the other arranged to push the first bladder axially inwardly to complete the fold of the band flat upon itself. A preferred form of deck comprises a plurality of readily replaceable segments which are mounted in a self-aligning manner on a radially expandable and rotatable hub. Each segment includes a pair of interfitting outer deck sections which are movable axially of the drum towards and away from each other to expand and contract the width of the deck in precise increments. Various forms of the deck further comprise spring gap shields or elastic gap spanning bands which circumscribe the deck at the deck edges. The various components are readily interchangeable with components of different sizes and adjustable to accommodate different sizes of tire components.

Abstract: In the case of a composite bridge beam, a perfect connection between the steel and concrete components exists only theoretically. In some types of connector design a rigid connection is achieved, others are more deformable and so a certain slip of the concrete deck with respect to the steel flange is inevitable. The problem is described as more severe when fewer connectors than the number required for full interaction are used. The influence of a deformable connection on the stress level and deflections of composite beams is investigated by the folded plate theory from which a versatile method of analysis is developed. Conclusions and recommendations for practical use of the method, derived from a parametric study, are also presented. (Author/TRRL)

Abstract: A convergent series solution, using the concept of equivalent orthotropy, is employed to analyze continuous composite bridges under static loads. The effect of the interaction between prestressing a portion of the deck slab and shear connectors in the region of the intermediate supports is examined. It is shown that prestressing the deck slab increases substantially the cracking load as well as the stiffness of such bridges. Results from tests on two bridge models verify and substantiate the theoretical analysis.

Abstract: A suspension bridge has a first deck 10 supported from a pair of suspension cables 14 and 15 by hangers 12 and 13 and a second deck 11 independently supported from a pair of suspension cables 18 and 19 by hangers 20 and 21. The two parallel decks are separated by a gap whose width is not less than that of either of the decks and is preferably three or more times the width of a deck. The decks are joined at intervals diagonal shear braces so that the two decks behave essentially as a single rigid body in regard to rotation in the plane of Figure 2. This results in very high aerodynamic damping of both torsional and bending modes of oscillation.

Abstract: Replacement of deteriorated and obsolete bridge decks is requiring increased attention from design and construction engineers. The need to shorten the time the bridge is closed to traffic has led to the use of precast concrete deck systems. Their value is demonstrated on bridges that must carry traffic for some portion of every 24-h period. Precast deck modules have been used on such diverse projects as expressway bridges in Pennsylvania and California and railroad bridges in British Columbia and Delaware. The Santa Fe Railroad has begun a multiyear program to replace timber decks with precast concrete on its 32 miles of bridges that have timber-deck and steel-girder designs. The precast deck modules used on these projects were produced at the site or produced at multipurpose plants and shipped to the bridge site. Placement was made with combinations of welded, epoxy, and cement-grouted connections. This paper reports on the state of the art of precast concrete deck replacements, their application in reconstruction, and their influence on deck design in new construction. (Author)

Abstract: The hull can transform a windsurf board into a catamaran. The board has two shells (1,2) which are mirror images and form the board when assembled. The two shells are retained together by fastenings, but can be released and retained parallel to one another by a deck (20) to form a catamaran. The two shells may be rotated through 90 degrees between their connected and separated positions. The fastenings can be formed by inserts with double flanges engaging in shaped apertures in the boards.
