Description
Technical field
The utility model relates to the structures that a kind of raising panel connect with cross member fatigability.
Background technique
Orthotropic Steel Bridge Deck is a kind of common structure type in steel structure bridge.Wheel load repeated action is in bridge
Lead to Orthotropic Steel Bridge Deck fatigue damage easy to form on panel.In each structure detail of steel bridge deck, longitudinal rib and cross
Due to geometrical construction complexity, stress is sufficiently complex, is easy to happen fatigue crack for the junction of partition.There are two types of at method at present
Reason: a kind of processing method is diaphragm plate not notch, does not set although processing, lower groove and polishing that notch avoids notch, but
Compared with using the construction of notch, under wheel load repeated action, longitudinal rib bottom is very high since out-of-plane bending can generate
Stress amplitude causes fatigue crack to generate；Another kind is the diaphragm plate notch at longitudinal rib process, the diaphragm plate below longitudinal rib
Arc incision is arranged to mitigate since longitudinal rib bends the bending deformation driven outside tabula plate face, reduces issuable on diaphragm plate
High face external carbuncle, but arc incision still has biggish stress to concentrate, and due to notch there are parts to have hollowed out diaphragm plate abdomen
Plate, so that diaphragm plate stress is unfavorable, therefore diaphragm plate arc incision is also that the fatigue of the Orthotropic Steel Bridge Deck of steel box-girder is opened
One of sensitive details are split, mainly include that crossbeam arc incision circumferential crack, crossbeam arc incision crack on end side and longitudinal rib-crossbeam connect
Connect longitudinal rib siding horizontal crackle and the vertical rifts etc. of welding end.
