Abstract

In order to study the reasonable installation lengths of zero block concrete segment in prestressed concrete box-girder beams with corrugated steel webs, a numerical analysis on the length of different zero blocks in PC box girder beams with corrugated steel webs is made by the finite element software ANSYS. The influence of the installation lengths of zero block concrete segment on the structure control section's internal forces and deformation is discussed. The results indicate: the impact of length changes of zero block on box girder deflection is greater than its impact on internal forces; in terms of deflection, the displacement influence in quarter-section in middle span is the largest; and in terms of internal forces, the internal forces influence of the junction section formed by zero block concrete segment and beam segment with corrugated steel webs is the largest. According to the above results and the relevant information of constructed bridges, the reasonable setting length of zero block concrete segment has been provided, that the ratio L0/L of installation lengths and span for zero block of box girder should be in the range of 0.05 to 0.10.
