STUDY ON STUD ARRANGEMENT AND ITS SHEAR FORCE RESPONSE AT ENDS OF COMPOSITE GIRDER USING PRECAST CONCRETE SLAB

Abstract

 In this study, several stud arrangement patterns at the girder ends of the composite girder were assumed, and the shear force responses of the studs caused by the design action such as drying shrinkage and temperature change were obtained. The shear response of the studs was calculated using the rigid-body-spring model analysis.

 As a result, the shear forces of the studs in the composite girder model due to the effects of drying shrinkage and temperature change are very large at the girder ends, and superposed shear force does not satisfy the serviceability limit condition. However, when those actions are applied continuously for those stud arrangement patterns at the girder ends, the maximum shear force of the studs is considered to be acceptable for the serviceability limit condition.
