Abstract: This paper provides a comprehensive review of various methods used for skin buckling analysis in composite components. The skin buckling phenomenon is one of the governing criteria in composite design. It is a kind of contact buckling in which partial sections of skin buckle away from the filler material. In general, the problem can be modelled as a thin plate (skin) in unilateral contact with elastic medium (filler material). The theoretical analysis of contact buckling is complicated due to the nonlinearity arising from changing contact regions. To simplify the calculations, the filler material was usually modelled as a tensionless elastic foundation. The skin buckling coefficient varies in terms of the relative foundation stiffness factors. Because the Eigen-value method is not applicable to nonlinear systems, the finite element (FE) method was usually employed for post-buckling analysis, while initial buckling performance was investigated through analytical or semi-analytical methods such as rigid foundation model, infinite plate model and finite plate model. The compressive buckling and shear buckling problems for thin plates resting on tensionless foundations have been solved successfully. However, there are still urgent needs for future research on the topic. For ex le, the load carrying capacity of the buckling plates needs to be formulated for practical application. Complicated problems with complex loadings and/or corrugated skins need further investigation as well.

Abstract: In this paper, a practical design procedure for thin-skinned steel-composite composite panels subjected to axial or flexural loadings is developed. Ignoring the adhesive forces between steel and core concrete, steel skins may be modeled as thin plates resting on tensionless rigid or elastic foundations (concrete material). Sections of steel skin tend to become separated (delaminated) from the core concrete and buckle away from it, while other areas keep contact with the inside material. This phenomenon is named as contact buckling. Based on the governing equations of thin plates in contact area and noncontact area, initial buckling response of thin skins may be obtained. Then it becomes possible to use effective width-based formulas to deduce ultimate strengths of the unilaterally constrained skins. At last, design formulas for section capacity of composite members due to axial and flexural loadings are developed.

Abstract: This paper addresses the compressive local buckling behavior of an infinitely long laminated composite plate resting on a tensionless elastic foundation (Winkler foundation). The analytical solution to the contact buckling coefficient of a laminated composite plate is derived using a one-dimensional analytical method. Numerical ex les are considered to investigate the influence of the ply angle and foundation stiffness on the contact buckling coefficients of laminated composite plates under uniaxial compression. The lateral boundary conditions including cl ed and simply-supported edges are treated. Finally, finite element (FE) analysis is conducted to provide an independent check on the analytical solutions.

Abstract: A nonlinear force method model is proposed to study the dynamic behavior of cable trusses. In the paper, travelling wave method is employed to solve the governing equation of motion. After support reaction forces are considered as excitations, cable trusses are extended to infinitude, and D’Alembert solution to the partial differential equation (PDE) is achieved. Substituting the solution into compatibility condition and boundary conditions, the governing equation expressed by dynamic tension is derived, which is named force method dynamic equation (FMDE). Hence the dynamic system of infinite-degree-of-freedom is simplified as a system with only one unknown without any loss of precision. Nonlinear governing equations are developed through considering the effect of quadratic terms of displacements. At last, an ex le is given to verify the force method model presented in the paper.

Abstract: In this paper, transmission line systems are modeled as multi-span cable structures. A force method model is proposed for analysing the static response of the multi-span cables with small sags. The accepted cable model reduces to two groups of differential equations (the equilibrium equations in y, z directions) and an integral equation (the compatibility equation). Substituting the differential equation solutions into the compatibility condition, the governing equation is obtained in terms of the tension component in chord direction. This equation has been named the force method equation (FME). In this way the infinite-degree-of-freedom dynamic system is effectively simplified to a system with only one unknown. Finally, one ex le is presented to illustrate the application of the proposed force method.

Abstract: This paper presents an investigation of the influence of pile-soil-structure interaction (PSSI) on the vibration control of adjacent buildings with pile foundations. With the initial assumption that adjacent buildings are linked by the control actuator of an ideal hydraulic servo-system, based on the Penzien model, the calculation model for adjacent structures with piled foundations considering PSSI is established. The motion and control equations of adjacent structures are then derived, and the influences of PSSI on vibration control of adjacent buildings analyzed. Finally, the influences of soil and structural parameters on structural vibration control are investigated. The results show that the PSSI has an obvious influence on the response of adjacent structures, but little obvious influence on the change in control force. However, the soil and structural parameters, such as shear-wave velocity and pile stiffness, play a significant role in the control process.

Abstract: Proposed herein is a new vibration-reduction technique for multi-adjacent-building systems subjected to earthquake excitations. Based on a three-building model, three different connecting methods are presented for reducing the seismic response of the multi-building system. After the equation of motion is derived, a numerical ex le is employed to demonstrate the seismic performances of the controlled systems. The vibration-reduction mechanism, the vibration-reduction effect, and the influential parameters are also studied. Numerical results show that the method of coupling adjacent structures is a viable and attractive vibration-reduction strategy for seismically excited structures.
