Abstract ：
This article investigates a comprehensive analysis of the bending problem pertaining to magneto-electro-elastic (MEE) nanobeams on the Winkler-Pasternak foundation. Taken into account the influence of size effects of nano structures, a non-classical mechanical model is established to describe the bending behavior for MEE nanobeams. In this research, the nonlocal modified couple stress theory is utilized to accurately capture both the softening and hardening effects resulting from the size effect. The theory of third-order shear deformation and von Karman geometric nonlinear theory are employed in conjunction with the introduction of Maxwell's equation to develop the model of MEE nanobeam, the control equation of the nonlinear bending problem of MEE nanobeams is obtained by Minimum potential energy principle, and it is solved by Galerkin method. Finally, this study provides a detailed discussion on the influences of the ratio of nonlocal parameters and length-scale parameters, Winkler-Pasternak coefficient, external magnetic potential, external voltage and span-thickness ratio on nonlinear deflection of nanobeam.

Abstract ：
With employing the von Karman plate theory, and considering the linearly thickness variation in one direction, the bending problem of a rectangular magnetoelectroelastic plates with linear variable thickness is investigated. According to the Maxwell's equations, when applying the magnetoelectric load on the plate's surfaces and neglecting the in-plane electric and magnetic fields in thin plates, the electric and magnetic potentials varying along the thickness direction for the magnetoelectroelastic plates are determined. The nonlinear differential equations for magnetoelectroelastic plates with linear variable thickness are established based on the Hamilton's principle. The Galerkin procedure is taken to translate a set of differential equations into algebraic equations. The numerical examples are presented to discuss the influences of the aspect ratio and span-thickness ratio on the nonlinear load-deflection curves for magnetoelectroelastic plates with linear variable thickness. In addition, the induced electric and magnetic potentials are also presented with the various values of the taper constants.

Abstract ：
Ride comfort is very important in the performance evaluation of highway concrete pavements. In this paper, three indices were integrated and used for the evaluation of ride comfort on asphalt concrete pavements: (1) weighted root mean square of the acceleration, (2) root mean square of the squared differences (a measure of heart rate variability), and (3) weighted value of subjective ride comfort. The study involved collection of comprehensive experimental data for 89 highway sections in China that included pavement roughness, ride speed, acceleration, dynamic friction, psychological and physiological data, pavement condition, and questionnaires. Indices and thresholds for acceleration, heart rate variability, and subjective evaluation of ride comfort were developed. In addition, quantitative relations between ride comfort and both pavement roughness and ride speed were established for two specific ranges of dynamic friction. Graphical relations among ride comfort, pavement roughness, and ride speed were established. These relations provide useful guidelines for ride comfort evaluation and highway maintenance management.

Abstract ：
为了研究粘结层界面脱层破坏对钢桥面铺装结构温度应力的影响，采用有限元软件建立钢桥面铺装结构模型，施加温度荷载（基准温度35℃，铺装面层65℃，钢板底面45℃），分析粘结层不同脱层面积及不同脱层形式下铺装结构温度应力的变化情况。计算结果表明：粘结层界面脱层对铺装结构的温度应力影响显著，在贯穿脱层情况下，铺装结构的温度应力随脱层面积的增大而增大，50％面积脱层时的层间应力是完整粘结时的2倍多；粘结层不同脱层形式对铺装结构温度应力的影响不同，其中中间脱层对铺装结构的温度应力几乎没有影响，贯穿脱层、间隔脱层和旁边脱层由于破坏了层间粘结的整体性，对铺装结构温度应力影响较大。

Abstract ：
With employing the transverse shear deformation theory and von Karman plate theory, the nonlinear static behavior of a simply supported rectangular magnetoelectroelastic plates is investigated. According to the Maxwell's equations, when applying the magnetoelectric load on the plate's surfaces and neglecting the in-plane electric and magnetic fields in thin plates, the electric and magnetic potentials varying along the thickness direction of the magnetoelectroelastic plates are determined. The nonlinear differential equations for magnetoelectroelastic plates are established based on the Hamilton's principle. The Galerkin procedure furnishes an infinite system of differential equations into algebraic equations. In the numerical calculations, the effects of the nonlinearity and span-thickness ratio on the nonlinear load-deflection curves and electric/magnetic potentials for magnetoelectroelastic plates are discussed. © 2016 Trans Tech Publications, Switzerland.

Abstract ：
In order to provide a theoretical basis for the ride comfort level evaluation, daily management, and maintenance of asphalt concrete pavement, the performance parameters and three-directional acceleration data of highway pavements were measured indoors and outdoors. Using these data, the relationship between the mean square of weighted acceleration and the pavement performance was studied. A linear regression equation that reflects the relationship between the root mean square of weighed acceleration, speed, and roughness was obtained by fitting 214 groups of experimental data. In addition, the outdoor experimental results were verified using a driving simulator. The results show that the root mean square of weighed acceleration is strongly correlated with roughness, moderately correlated with the speed, and weakly correlated with the dynamic friction coefficient. Given a certain dynamic friction coefficient, the ride comfort level of an asphalt concrete pavement reduces with its roughness and driving speed increasing. When the roughness is 1.35 and 3.05 mm/m, the maximum speed with an appropriate ride comfort level is 124.1 and 88.7 km/h, respectively.
