ABSTRACT

ABSTRACT: Through the three reciprocating cycle tensile experiment of the approach pavement of the pre-cut semi-integral jointless bridge, get the variable datum of the friction resistance, anchorage force and crack width and put forward the design requirement of the anchorage beam of the bridge. Through the destruction experiment of the semi-integral jointless bridge with grade beam and bringing in the displacement ductility calculation formula, analyses the ductility of the semi-integral jointless bridge. The results proved that the integrity of the semi-integral jointless bridge is strong. Meantime in order to calculate the crack width of the approach pavement we bring in the cyclic loading influence coefficient to consider the influence of the reciprocating temperature load to the approach pavement.
