The PBL (Perfobond Leiste) shear connector has the advantages of high bearing capacity and strong constraint ability; however, traditional weak axis problems, its stiffness is large, resulting in deformation ability. To this end, paper proposes a new type flange triple-web key obtains key’s mechanical properties failure mechanism through push-out test. results show that mode steel plate on web ...

Steel coupling beam (SCB) is a substantial member of the hybrid coupled walls system. When are linked by SCB rather than conventionally reinforced or diagonally beams, system’s strength and energy dissipation capacities greatly enhanced. A corrugated web may be used in instead flat to improve these characteristics even more. This paper presents an experimental numerical investigation shear-carr...

this study presents exact bending solution of fully clamped orthotropic rectangular plates subjected to arbitrary loads resting on elastic foundations, based on the finite integral transform method. in this method, it is not necessary to determine the deformation function because the basic governing equations of the classical plate theory for orthotropic plates have been used. a detailed parame...

this paper presents the bending analysis of annular plates by the indirect trefftz boundary approach. the formulation for thin and thick plates is based on the kirchhoff plate theory and the reissner plate theory. the governing equations are therefore a fourth-order boundary value problem and a sixth-order boundary value problem, respectively. the trefftz method employs the complete set of solu...
