Abstract: A nonlocal sinusoidal plate model for micro/nanoscale plates is developed based on Eringen’s nonlocal elasticity theory and sinusoidal shear deformation plate theory. The small-scale effect is considered in the former theory while the transverse shear deformation effect is included in the latter theory. The proposed model accounts for sinusoidal variations of transverse shear strains through the thickness of the plate, and satisfies the stress-free boundary conditions on the plate surfaces, thus a shear correction factor is not required. Equations of motion and boundary conditions are derived from Hamilton’s principle. Analytical solutions for bending, buckling, and vibration of simply supported plates are presented, and the obtained results are compared with the existing solutions. The effects of small scale and shear deformation on the responses of the micro/nanoscale plates are investigated.

Abstract: In this paper, the Ritz-based solutions are developed for the bending, buckling and vibration behaviors of laminated composite beams with arbitrary lay-ups. A quasi-3D theory, which accounts for a higher-order variation of both the axial and transverse displacements, is used to capture the effects of both shear and normal deformations on the behaviors of composite beams. Numerical results for various boundary conditions are presented and compared with existing ones available in the literature. Besides, the effects of fiber angle, span-to-height ratio, material anisotropy and Poisson’s ratio on the displacements, stresses, natural frequencies and buckling loads of the composite beams are investigated.

Abstract: This paper investigates the behavior of high‐rise composite buildings with composite shear walls and concrete‐filled steel tubular (CFST) columns using a numerical model in OpenSees. In the model, the geometric and material nonlinearity of structural elements are captured by utilizing a fiber force‐based beam‐column elements with rigorously modified material stress–strain relationships. Besides, the confining effect of the concrete core, the semi‐rigid connections, and the coupling effect of composite shear walls is carefully taken into consideration. Finally, the case study of a 42‐storey composite building is conducted using the proposed model to provide a thorough understanding about the behavior of this kind of building. It shows that this innovative building has high loading capacity and significantly reduces the dimension of structural members (up to 50%) compared with the conventional RC building at the same loading capacity. Through the validation with test data, the suggested constitutive laws have shown the simplicity and high accuracy since the value of model error is only around 7%. In addition, the simulation results also indicate that the model can capture well the nonlinear behavior of tested specimens, especially, the failure and the formation of plastic hinges of coupling composite shear walls implicitly.

Abstract: An improved transverse shear stiffness for vibration and buckling analysis of functionally graded sandwich plates based on the first-order shear deformation theory is proposed in this paper. The transverse shear stress obtained from the in-plane stress and equilibrium equation allows to analytically derive an improved transverse shear stiffness and associated shear correction factor of the functionally graded sandwich plate. Sandwich plates with functionally graded faces and both homogeneous hardcore and softcore are considered. The material property is assumed to be isotropic at each point and vary through the plate thickness according to a power-law distribution of the volume fraction of the constituents. Equations of motion and boundary conditions are derived from Hamilton’s principle. The Navier-type solutions are obtained for simply supported boundary conditions, and exact formulae are proposed and compared with the existing solutions to verify the validity of the developed model. Numerical results are obtained for simply supported functionally graded sandwich plates made of three sets of material combinations of metal and ceramic, Al/Al 2 O 3 , Al/SiC and Al/WC to investigate the effects of the power-law index, thickness ratio of layer, material contrast on the shear correction factors, natural frequencies and critical buckling loads as well as load–frequency curves.

Abstract: This article presents analytical solutions for buckling analysis of functionally graded plate based on a refined plate theory. Based on the refined shear deformation theory, the position of neutral surface is determined and the governing stability equations based on neutral surface are derived. There is no stretching–bending coupling effect in the neutral surface-based formulation, and consequently, the governing equations and boundary conditions of functionally graded plates based on neutral surface have the simple forms as those of isotropic plates. The closed-form solutions of buckling load are obtained for rectangular plates with various boundary conditions. The accuracy of neutral surface-based model is verified by comparing the obtained results with those reported in the literature. Finally, parameter studies are carried out to study the effects of power law index, thickness ratio, and aspect ratio on the critical buckling load of functionally graded plates.

Abstract: A new four-node quadrilateral plate that accounts for shear deformation effect and all couplings from the material anisotropy is developed for laminated composite plates. Lagrangian linear interpolation functions are used to describe the primary variables corresponding to the in-plane displacements, while Hermitian cubic interpolation functions are considered for the transverse displacement. Since the present element is derived based on a refined plate theory that has strong similarity with the classical plate theory, it is capable of modeling both thin and very thick plates without shear locking. The accuracy of the present formulation is verified by comparing the results obtained with those available in the open literature. Numerical results are presented to investigate the effects of thickness ratio, lamination angle and lay-up on the shear deformation and response of laminates.

Abstract: This study examines the use of steel fibers in enhancing the ductility of an economical ultra‐high strength concrete (UHSC). The addition of fibrous material with very small geometry in this mixture is an effective solution to improve its ductility and prevent its brittle failure which is a common characteristic of UHSC. Different mechanical properties of reinforced and unreinforced concrete (e.g., slump flow, compressive, splitting tensile strength tests, and failure modes) were taken into account to find out the efficiency of micro steel fibers. The test results showed that concrete containing 25 mm length and 0.20 mm diameter steel fibers at a volume fraction of 0.5% not only presented a reasonable improvement in ductility performance but also ensured cost‐effectiveness. The cost evaluation conducted on several existing mix designs is also introduced in this study to investigate the influence of various steel fiber contents on the total cost of concrete so that figure out the lowest budget solution. The evaluation shows the high price of fiber reinforcement in which an addition of steel fibers by 5% volume could increase 7% of the total concrete cost.

Abstract: In this paper, an efficient computational approach is developed to investigate the free-vibration behavior of functionally graded plates. The problem is developed based on a three-dimensional elasticity theory, which is expected to capture the structural response accurately. Isogeometric analysis is employed as a discretion tool to solve the problems. The accuracy of the proposed approach is verified by comparing the obtained results with those available in the literature. In addition, various ex les are also presented to illustrate the efficiency of the proposed approach. There are five types of plates with different configurations of material gradations. The benchmark results for those are also given for future investigations. Keywords: multi-directional functionally graded materials 3D elasticity isogeometric analysis free-vibration.

Abstract: Buckling, free and forced vibration analyses of orthotropic plates are studied numerically using Isogeometric analysis. The present formulation is based on the classical plate theory (CPT) while the NURBS basis function is employed for both the parametrization of the geometry and the approximation of plate deflection. An efficient and easy-to-implement technique is used for imposing the essential boundary conditions. Numerical ex les for free and forced vibration and buckling of orthotropic plates with different boundary conditions and configurations are considered. The numerical results are compared with other existing solutions to show the efficiency and accuracy of the proposed approach for such problems.
