A two-layer (connected by stubs) partial composite plate is a structure with outstanding advantages which can be widely applied in many fields of engineering such as construction, transportation, and mechanical. However, studies are scarce in the past to investigate this type of structure. This paper is based on the new modified first-order shear deformation plate theory and finite element method to develop a new four-node plate element with nine degrees of freedom per node for static bending and vibration analysis of the two-layer composite plate. The numerical results are compared to published data for some special cases. The effects of some parameters such as the boundary condition, stiffness of the connector stub, height-to-width ratio, thickness-to-thickness ratio between two layers, and aspect ratio are also performed to investigate new numerical results of static bending and free vibration responses of this structure.

“…The exact static analysis of composite beams with partial layer interaction was presented in Girhammar and Pan [10]. Static buckling of composite beams and beam columns was more recently treated, for example, in [6,12,21,28]. In more sophisticated approaches, an inelastic relation between interlaminar shear traction and slip on the static deflection is considered.…”

This paper addresses moderately large vibrations of immovably supported three-layer composite beams. The layers of these structural members are elastically bonded, and as such, subjected to interlayer slip when excited. To capture the moderately large response, in the structural model a nonlinear axial straindisplacement relation is implemented. The Euler-Bernoulli kinematic assumptions are applied layerwise, and a linear interlaminar slip law is utilized. Accuracy and efficiency of the resulting nonlinear beam theory are validated by selective comparative plane stress finite element calculations. The outcomes of application examples demonstrate the grave effect of interlayer slip on the geometrically nonlinear dynamic response characteristic of layered beams.

“…A closedform prediction of buckling stress in local mode, including interaction of connected elements, and distortional mode, including consideration of the elastic and geometric stiffness at the web/flange juncture was conducted [3]. A mathematical model for slip buckling and its analytical solution has been founded for the analysis of layered and geometrically perfect composite columns with inter-layer slip between the layers was proposed [4]. Also, buckling of non-uniform column was analysed using Finite Element Analysis [5].…”

Abstract. The brace configuration plays an important role to the ultimate strength of fixed jacket platform. The braces against the combined load in vertical and horizontal direction. In the present study, the ultimate strength of the fixed jacket platform is analysed considering the shape of the structural geometric. Four types of brace configuration namely, K, N, X and Y are taken to be assessed. Dimensions of the structure are constant including properties and materials. The boundary conditions are assumed to be fixed at the bottom part. The Non-Linear Finite Element Analysis (NLFEA) is adopted to calculate the ultimate strength of the structure and those results of brace configuration are compared with one another and discussed in the present study.
