Behaviour Analysis and Engineering Calculation of the Stress-ribbon Bridge with External Tendons / Dvijuoscio Lankstaus Kabamojo Plieno Tilto Elgsenos Analize Ir Inžinerinis Skaiciavimas

The current article discusses a single-span composite steel pedestrian bridge, the load-bearing structure of which is comprised of a stress-ribbon with extended tendons. The analysis is focused on the behaviour of such structure under symmetric loads. The article reviews the general displacement thrust force of load-bearing suspension structures of such bridge as well as presents calculation analysis values of such displacements and the thrust force. In addition, it provides results of the numerical experiment and comparative analysis of the stress-ribbon structure with extended tendons.
