Abstract

 According to Japanese specifications for highway bridges, the frictional bolted connection has had to carry out to be safe for the major slip or the member yield. On the other hand, other specifications based on the Limit State Design method permit the connection to design for after major slip. Therefore, it is desirable that the after major slip design is also possible in Japan to convert the Allowable Stress Design to the Limit State Design method. However, the present Japanese bearing strength of bolted connection is lower than foreign. In addition, the initial residual axial force may be able to tolerate greater bearing stress than non tightening connection. Therefore, we carried out the test of frictional bolted connections to measure the limit-bearing-stress based on hole deformation and reveal mechanical behavior of them. Furthermore, we tried the quantitative evaluation of the effect of frictional force remaining after the major slip.
