The purpose of this paper is to use static and dynamic load tests evaluate the mechanical performance a simply supported skew slab bridge its actual bearing capacity. Firstly, Midas Civil software used for theoretical simulation, secondly, deflection, strain, response key section are studied through tests. Finally, measured values compared analyzed. results show that: under load, relative resid...

Layout line of bridge structure is a direction which used to define the horizontal and vertical alignment structure. The objective this study evaluate optimize different designs outline turn compare results with layout straight using dynamic analysis according finite element method. Dynamic showed that most models have converging values natural frequency except Model No. F. it explains higher r...

Abstract Prestress is an important index of the mechanical performance prestressed structures, which will have a certain impact on natural vibration frequency structure. In this paper, based action mechanism prestressing system, externally simply supported steel beams are classified, and energy method used to establish dynamic equations with three forms cable distribution, view exploring relati...

In the current industry, steel–concrete composite beams are used in large-span bridges and super-high-rise building structures due to their excellent overall performance. Concrete’s creep slip effects combined structure can adversely affect structure, thus affecting safe use of buildings. It is necessary study mechanical properties considering slip. order further under creep–sliding coupling, t...

In this paper, classical thin shell theory is used to analyze vibration and critical speed of simply supported rotating orthotropic cylindrical shell. The effects of centrifugal and Coriolis forces due to the rotation are considered in the present for‌mulation.. In addition, axial load is applied on cylinder as a ratio of critical buckling load. Finally the effects of orthotropic ratio, materia...

The thermomechanical buckling of simply supported thin shallow spherical shells made of functionally graded material is presented in this paper. A metal-ceramic functionally graded shell with a power law distribution for volume fraction is considered, where its properties vary gradually through the shell thickness direction from pure metal on the inner surface to pure ceramic on the outer surfa...

In this paper, the crack detection and depth ratio estimation method are presented in beamlikestructures using Elman Networks. For this purpose, by using the frequencies of modes asinput, crack depth ratio of each element was detected as output. Performance of the proposedmethod was evaluated by using three numerical scenarios of crack for fixed-simply supportedbeam consisting of a single crack...

The present article deals with the analysis of thermal-bending stresses in a heated thin annular sector plate with simply supported boundary condition under transient temperature distribution using Berger’s approximate methods. The sectional heat supply is on the top face of the plate whereas the bottom face is kept at zero temperature. In this study, the solution of heat conduction is obtained...
