摘要

A walking bridge was made by KWPA at 1992, on overflow structure, south of Iran. The traffic load forced to build a new bridge on main water channel that it should be carry semi-heavy traffic load. For each span; the one of two connections of the beam was jointed in each side and the other joint was without any connection with column. The main criterion was considered by designer into separate stiffness that the old bridge should be carry the weight of the dead load and the other stiffness should be computed to carry the live load. New steel bridge should be transferring the torsion into column that it is produced by motion of traffic live load. New opener connection could be solved the problem and it was invented by designer Afshin Turk 2002. The cost of modify bridge would be consider 7% of total cost of wide bridge (150m).
