Pipeline bridge Siu Saka Nelahozeves:
ing. Emanuel Novák, ing. Vladimír Chmelař, 2002
Controlling of the technical state pipe bridge and reduction of the bridge´s load usefulnes. A calculation has been made due to nonlinear theory of 2nd grade, dynamical calculation of it´s mode shapes and frequnces and dynamical effects of the wind. Dynamic coefficient for horizontal deformation (strain) is approximately "1". natural frequency and shapes of the bridge were set inclusive of initial prestress. Results of the statical calculation were compered with calculation thanks to the affinities (relations) for the cable structures, good harmony (correspondence) can be acknowledged.projekt »
