Yde Engineers Bridges And Civil Engineering Structures

I. Stern – Y.D.E. Engineers LTD Bridges and Civil Engineering Structures I. Stern - Y.D.E. Engineers LTD. is experienced in the design of prestressed concrete bridges. The company is specialized in the spliced girders method. The company has developed a special method for optimization of post-tension tendon profiles. This method, while applied in spliced girder bridges, allows using precast girders of standard sections for longer spans. Zohar Bridge is composed of standard precast AASHTO VI girders with 52 meter spans. A bridge in road 431 is composed of standard channel girders 1.80 meter deep with 54 meter spans. The development of this method enables reducing up to 20% of the structure cost, compared to alternative methods for this span range like segmental box girder bridges. Using this method reduces the depth of bridge superstructures and achieves the best span/depth ratio for bridges composed of precast elements. The company designs integral abutments bridges, including bridges with large diameter concrete piles up to 80 meters long. The integral abutments bridges avoid the need for bearings and expansion joints, reducing construction cost and dramatically minimizing the maintenance cost. The integral abutments bridges improve the riding quality of vehicles. Accurate analysis for the creep, shrinkage and temperature difference effects and the foundation soil interaction is accomplished resulting in a very well performing bridge.
