  • RELATIONSHIP OF MACRO STRESS AND MAXIMUM PRINCIPAL STRESS ON ELECTRO-SLAG WELD ZONE BETWEEN INTERIOR DIAPHRAGM AND BOX COLUMN

抄録

<p>In the Electro-slag welding(ESW) joint, under severe earthquakes, it is worried about an early brittle fracture in the tip of a slit between a skin plate and a backing strip. According to the previous experimental and analytical studies, between the fracture toughness where the fractures initiate and the equivalent maximum principal stresses (MPA) obtained by the finite element analysis (FEA) was roughly positive correlated. It suggests that the required fracture toughness to prevent the brittle fracture of ESW joint can be estimated if the MPA around the tip of a slit in ESW joint is obtained. Therefore, in this paper, the method of calculating the MPA of ESW joint without carrying out FEM, by converting the macro stress of interior diaphragm, is proposed.</p>
