Stay deformation, affect the mechanical property of steel plate.Owing to steel plate is relatively thin, welding is got up and easily " is burnt ",
A large amount of welding positions are inevitably present crackle, the defect such as are mingled with, and under reciprocating load, split
Stricture of vagina extends the most rapidly and brittle fracture quickly occurs, and reduces the ductility of steel plate.Secondly, ribbed stiffener is easy
Cripling occurring and reduces the efficiency of putting more energy into of ribbed stiffener, cripling repeatedly accelerates ribbed stiffener
Fracture, finally loses distortion.
Opening perps on steel plate, the overall detrusion becoming steel plate is the flexural deformation of column between seam, from
And improve the ductility of plate, but construction technology is complex.Owing to steel plate is split, the road of pulling force field
Footpath is obstructed, it is difficult to form complete pulling force field, thus the bearing capacity provided is limited.Secondly, perps
