Experimental study is carried out to examine the behaviour of in-situ stitches under different combinations of internal forces. Failure of stitches may occur under exceptional circumstances that may potentially trigger a progressive collapse. Formulae for strength estimation are proposed based on the results.

Performance of in-situ concrete stitches in precast concrete segmental bridges. A finite element programme for post-peak analysis is therefore developed for the present study. The results indicate that any span of a multispan bridge may become a temporary end-span in the event of collapse of an adjacent span and the strength of the sections must be designed accordingly to prevent progressive failure.

However, relatively little research in this area has been carried out. The author retains all proprietary rights, (such as patent rights) and the right to use in future works. Subsequent parametric studies are conducted numerically to examine the effects of various parameters on the load-displacement characteristics of the stitches.

A gap of 100 to 200 mm wide is usually provided around the mid-span location between the last two approaching segments to facilitate erection. Formulae for strength estimation are proposed based on the results.

    Experimental study is carried out to examine the behaviour of in-situ stitches under different combinations of internal forces. As a span becomes a temporary end-span, the in-situ concrete stitches may experience substantial moment and shear, and their failure could potentially trigger progressive collapse of the entire bridge deck. The author retains all proprietary rights, (such as patent rights) and the right to use in future works.

    Substantial redistribution of internal forces along the deck is observed as failures initiate, thus causing subsequent failures of other deck sections even though they have been designed to resist the internal forces at the ultimate limit state. Subsequent parametric studies are conducted numerically to examine the effects of various parameters on the load-displacement characteristics of the stitches. Performance of in-situ concrete stitches in precast concrete segmental bridges. However, relatively little research in this area has been carried out.
