A Study on Space Numeric Simulation of Long Cantilever for PC Continuous Box Girder on Model Bridge

Aiming at transverse mechanics performance of transverse long cantilever for PC box girder on model bridge,according to similarity principle,the transverse long cantilever for PC box girder on model bridge is made,the study on space numeric analysis about transverse long cantilever for PC box girder on model bridge can be carried out for three dimension solids based on ANSYS.Considering two hypothetical cases of eccentric loads and concentrate loads for transverse long cantilever beam,the deflection and stress are studied.Test results indicate: the result of space numeric simulation is approximate to test one,and with high accuracy.Because the ration of width to length is large,partial load effect is obvious,transverse long cantilever beam is similar to single beam,its oblique direction r is exposed to eccentric loads,and it appear U shape while concentration loads is acting on the two sides of transverse long cantilever beam.
