To better understand the behavior of composite beams in buildings, push-out tests were conducted to study the behavior of welded shear studs. Forty-eight solid slab push-out tests were conducted to study how stud tensile strength and concrete properties affect the strength of shear connections. It is shown that raising the tensile strength of a shear connector actually has an adverse effect on the connector's performance and strength. It is also shown that the upper limit for shear strength used in the current AISC specification (Load 1993) is unconservative and a lower upper limit is proposed. Eighty-seven pushout tests utilizing steel deck were also conducted. It is shown how the placement, height, and arrangement of shear studs, as well as the height and gage of steel deck affects the strength of shear connections when stiffened steel deck is used. It is shown that the current AISC specification is unconservative and does not account for the many failure mechanisms associated with connections using steel deck. It is shown how tension within the stud shank, friction at the slab/beam interface, and steel deck strength affect the strength of shear connections. / Master of Science

The stresses and deformations in cross-ply composite tubes subjected in circumferential temperature gradients are studied. The motivation behind the study is the anticipated use of composite tubes in space structures where the tube is exposed to the heat of the sun on one side and the cryogenic temperatures of space on the other. Experiments were performed to measure the functional form of the temperature gradient and the displacements. It was found that the form of the temperature gradient, T(Ɵ), can accurately be represented by T(Ɵ) = A + BcosƟ¸ and that the displacement of the tube is parabolic in the axial coordinate. Two types of analytical solutions were developed: an exact elasticity U solution and an approximate solution. The approximate solution includes a linear variation of the material properties with temperature and uses the principle of complementary virtual work in conjunction with a Ritz approximation on the stress field. The elasticity solution predicts that high tensile stresses could crack the matrix. The effect of including temperature-dependent material properties is to reduce the circumferential dependency of the stresses. / Master of Science
