This study deals with the dynamic behavior of the kavar concrete Abstract face rockfill damwhich is the first dam of this type to be const ructed in a highly active seismic prone area,situated in the state of Fars southern part of the Islamic Republic of Iran. The finite elementmethod was used as a tool to carry out this study. The finite element discretization was carriedout under plane strain...

In this study, a noncontact vision-based sensing method is proposed to measure surface displacements and curvatures and to detect cracks in a reinforced concrete slab. The proposed method includes five independent modules for structure boundary identification by a dynamic programming algorithm, boundary movement tracking by a contour tracking algorithm, distinguishable surface feature detection...

This paper investigates various aspects of the structural behavior of doweled joints, including load transfer, in rigid airport pavement systems using nonlinear three–dimensional finite element methods. The finite element models include two concrete slab segments with dowels connecting them. The concrete slab and supporting layers are simulated by continuum solid elements to enhance the accurac...

Concrete slab with opening are usually designed with help of traditional rules of thumb proposed by building codes. Such methods however introduce limitations concerning size of opening and magnitude of applied loads. Furthermore there is a lack of sufficient information about the load carrying capacity of slab with opening. It is also difficult to model the complex behaviour of reinforced conc...

Slab-girder structures composed of steel girder and reinforced concrete slab are widely used in buildings and bridges in the world. Their advantages are largely based on the composite action through the shear connection between slab and girder. In order to assess the integrity of this kind of structures, numerous vibration-based damage identification methods have been proposed. In this study, a...

In engineering practice, slots of different shapes and orientations are made with a view to satisfy the functional requirements. The presence of slots increases the complexity of the analysis (by stress concentration) of structural members/elements. Studies have been commonly done on plain concrete slab with rectangular and circular opening, while only few studies have been done on slots of lar...

This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system. The requirements on the link slab in terms of material properties, dimensions, and reinforcement detailing are considered. Special focus is placed on the deflection capacity of the link slab and its fatigue performance. This paper discusses the choic...

Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on el...

For this purpose a finite element model specifically developed for the nonlinear analysis of steel-concrete composite beams is adopted. This finite element model includes material nonlinearity of slab concrete, reinforcement steel, beam steel as well as slabbeam nonlinear partial interaction due to the deformable shear connection. The inclusion of the partial interaction in the composite beam m...
