Abstract—This study was conducted to evaluate the seismic performance of weir structures using two different approaches: i) design response spectrum with respect to KBC 2009 in Korea and ii) acceleration of time history (PGA, 0.3011 g) obtained from 1994 Northridge earthquake. This paper provided the simple linear elastic 2D plane strain FE model with the material nonlinearity including soil-fo...

Thanks to the cantilever launching technique, arch bridge building has once again become popular throughout world. Today, these structures are one of three main types long-span bridges, along with suspension and cable-stayed bridges. Arch have a complex behavior during powerful earthquakes because rib is an element that primarily susceptible large axial compression force brought on by dead load...

In this paper, transverse and longitudinal vibration of nonlinear plate under exciting of orbiting mass is considered based on first-order shear deformation theory. The nonlinear governing equation of motion are discretized by the finite element method in combination with Newmark’s time integration scheme under von Karman strain-displacement assumptions. For validation of method and formulation...

reliable stress-strain behavior of concrete is necessary particularly when a member is subjected to combine bending and axial load and confinement effects should be accounted for. a unified theory for confinement of circular hollow sections is proposed herein, that can be extended to the case of solid and noncircular sections. the main aim of the model is to trace step-by-step the evolution of ...

efficiency of numerical methods is an important problem in dynamic nonlinear analyses. it is possible to use of numerical methods such as beta-newmark in order to investigate the structural response behavior of the dynamic systems under random sea wave loads but because of necessity to analysis the offshore systems for extensive time to fatigue study it is important to use of simple stable meth...

Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...
