this paper focuses on the adhesion failure between the asphalt wearing course and the steel plate, and the temperature influence on the mechanical behavior of the orthotropic deck. Orthotropic steel bridge decks (OSBDs) have been widely used in long span bridges with many advantages, however, the long-term performance of the asphalt wearing course is still questionable.

In this study, it is split into two main steps. First, an analytical design is proposed to define the desired parameters with affects of different flux air gaps. Then, a finite element approach is developed to simulate inductances, leakage and fringing fluxes, magnetic flux density and electromagnetic force with different flux air gaps.

A hybrid analytical-numerical solution is proposed to solve the problem of a laterally loaded pile with a circular cross-section in multilayered soils. In the pile-soil model, the lateral load is located at the pile head including both lateral force and bending moment. The single pile is considered as a beam on elastic foundation while shear beams model the soil column below the pile toe.

This study shows that the stirrups corrosion should receive more attention in the serviceability limit state due to its considerable effect on flexural behavior. Based on a parametric study, it shows that the effect of the crosssection loss of tension reinforcements on the load-carrying capacity of the corroded beam is more significant than the bond strength reduction.

The modulus reduction and damping curves represent the nonlinear behavior of soil under cyclic load. In the literature, those curves were produced from lab tests of soil at particular confining stresses. This study developed a set of parameters that can be used to normalize the modulus reduction and damping curves to be stress-independent.

A big question in the numerical approaches for the mechanical behavior of the textile-reinforced concrete (TRC) composite under tensile loading is how to model the cracking of the cementitious matrix. This paper presents numerical results of 3-D modeling of TRC composite in which the non-linear behavior model was used by considering the cracking for the cementitious matrix.

This paper addresses the strength and deformation capacity of slender columns retrofitted by externally bonded Carbon Fiber-Reinforced Polymers (CFRP) subjected to seismic loading. The behaviour of RC columns depending on the CFRP confinement (carbon CFRP jacket) and on flexural reinforcement (carbon plates) was analysed by a nonlinear finite element method based on multilayer shell element and multifiber beams with plasticity and damage models.
