A stress ribbon bridge is a very slender structure in which the deck hangs in a suspended cablelike form. DESIGN AND ANALYSIS OF STRESS RIBBON BRIDGES - Academia.edu For heavy vehicle traffic, certain degree of stiffness is required to prevent excessive flexure of the structure. Primitive bridge builders attempted to span distances wider than the length of an existing tree trunk by throwing a line across a ravine and tying it on both sides to a large rock or tree. III. application of prestressed concrete in bridges ppt. Japan's range of pioneering stress ribbon structures range from the longest single span bridge at 147.5 m to the world's first 3-directional stress ribbon bridge. The Shiosai Bridge in Shizuoka, Japan, is a prestressed concrete four-span stress-ribbon bridge with roadwayslab decks, which forms a so-called inverted suspension bridge. Touch device users can explore by touch or with swipe . Such, bridges are typically made from concrete reinforced by steel tensioning cables. KR20120072446A - Precast segment of the stress ribbon bridge and system The vertical dead load and live load are supported by the cables or ribbons in a high-tension state, and the deck slabs serve to transfer the live load to the ribbons.

The article looks into the behaviour of such suspension bridge under symmetrical and asymmetrical loads; it also presents analytical expressions for displacements, thrust forces and bending moments of such . One kind of these elegant and simple bridges consists of two hanging steel ribbons, usually made of steel, which carry concrete deck panels and are anchored between two heavy abutments. Problem. Suspension Bridge 48. The suspension cables are embedded in the deck, which follows a catenary arc between supports. The tendons are encased in ducts which are, generally grouted after tensioning in order to lock in the stress and protect them from corrosion. Structural analysis is similar to that of suspension bridges. Few people including bridge engineers are familiar with this form and fewer than 50 have been built worldwide.
