| 内容記述 | When reinforced concrete ( structures are seismically retrofitted, new members are connected via joint s with roughened surfaces and post installed dowel bars. For retrofit ted RC build- ings , roughened surface s are often manufactured using vibration hammer s . However, investigations on the shear strength s of the joints subjected to shear and tensile normal stress es are limited. In this study, these joints called hybrid joints, were subjected to shear loading . The test parameters we r e the normal stress dowel bar diameter d d and roughened c oncrete area ratio r rc . The normal stress was set to have a compressive stress σ 0 of 0.48 N/mm 2 and a ratio s r N o f tensile stress to yield strength of 0.00, 0.33 and 0.66. In addition, dowel bars with d d = 13, 16 , and 19 mm were used. The target r rc values were 0.1 0.2 and 0.3. Bearing failure of the roughened surface was observed as a result of the test. The shear strength decreased with increasing r N and decreasing r rc . Subsequently , an expression for the shear strength of a roughened surfac e wa s proposed. In this expression, the shape of an uneven surface was regarded as a cone. To estimate the shear strengt h s of the hybrid joint s , the shear force from the previous dowel model was added to the proposed expression. Finally, the values obtained us ing th e calculation method were compared with the test results . It was demon- strated that the proposed expression could r easonably estimate the test results , with a correlation coefficient of 0.93 . In addition, for structural design s , the proposed expression should be multiplied times 0. 7 to e stimate the lower limit of the test results. |
