BEARING BEHAVIOR OF HEADED STUD SHEAR CONNECTORS IN THE PUSH-OUT TEST WITH SIMPLE SUPPORT AND LATERAL RESTRAINT

Abstract

 A test specimen in the push-out test of the headed stud is generally supported by a floor and that support condition causes a lateral force acting the test specimen. This lateral force effects on the behavior of headed stud shear connectors during the test. A value of this force is not derived because the position of vertical reacting force under the floor support condition is uncertain. To solve this problem, a new push-out test of headed stud shear connectors with a simple support and a lateral restraint is proposed. This new push-out test is conducted under several conditions of support and lateral restraint, such as the location of simple support, with or without lateral restraint, and the bearing behavior of the test specimen in this push-out test is clarified. The test results show that the condition of support and lateral restraint change the boundary condition and the failure mode of test specimen.
