高力ボルト鋼板当て板補修部の荷重伝達機構に関する検討

For repair of cross section loss due to corrosion, repair using high strength bolted steel repair plates is often performed. Two kinds of splice plate of friction type connection using high tensile bolt are connecting plate and cover plate. Such repair is carried out in order to recover the load bearing capacity. However, the mechanism of load transfer of base plate and cover plate is not obvious enough. Therefore, in this study finite-element analysis of repaired connection model using high strength bolted cover plate subjected to tensile load and compressive load was carried out in order to clarify this mechanism. As a result, relationship between sectional area ratio and load sharing ratio was clarified.
