Outline of Final Research Achievements

For the headed anchor bolts and the bonded anchor bolts used for attaching structural and non-structural members to concrete structures, we studied aimed at establishing an evaluation method concerning with the following ;strength of cone-shaped fracture of concrete, bending yield strength of bolt and stiffness between shear force and horizontal displacement of anchor bolts.
As for strength of cone-shaped fracture of concrete, it showed that the cone-shaped fracture strength decreases by compressive force acting on concrete due to bending moment.
As for stiffness and flexural yield strength, we evaluated by the beam on elastic foundation theory and confirmed that it can be calculated accurately.
