Finite element analysis on torsional behavior of PC composite box-girder with corrugated steel webs

In order to further explore the torsional behavior of the PC composite box-girder with corrugated steel webs, three specimens are designed and fabricated for the monotonic pure torsion experiment. Finite element models of experimental beams are established, by adopting the method of space finite element analysis (FEA). By comparing the finite element calculation and the test results, the cure of torque - twist rate of the PC composite box-girder with corrugated steel webs are obtained, which confirms the reliability of the finite element analysis.
