Abstract The aim of the study is to demonstrate extent effect that occurs continuous reinforced deep beams when performing a parametric in terms support settlement and different conditions for dual span (CDBs), failure load mode, using ANSYS 2020 nonlinear finite element program. As relied on laboratory conducted by Yang et al. [8]. Six samples were taken from concrete with two spans extension ...

Abstract: Reinforced concrete elements with a high longitudinal and transverse reinforcement ratio may present conflicts on both of them, resulting in reduced labor productivity poor job when assembling the transversal reinforcement, reducing its effectiveness. Thus, this research presents type internal as an alternative to mitigate conflict between bars. A total 5 reinforced wide beams were ma...

The free vibration characteristics of steel-concrete composite continuous beams (SCCCBs) are analyzed based on the Euler–Bernoulli beam theory. A modified dynamic direct stiffness method has been developed, which can be used to analyze SCCCBs with some lumped masses and elastic boundary conditions. results obtained by proposed exact due elimination approximated displacement force fields in deri...

A complex network of Euler-Bernoulli beams is studied in this paper. As for this network, the boundary vertices are clamped, the displacements of the structure are continuous but the rotations of different beams are not continuous at the interior vertices. The feedback controller are designed at the interior nodes to stabilize the elastic system. The well-posed-ness of the closed loop system is...

Extensions of the Castigliano theorems are developed in the context of modeling the behavior of both discrete coupled linear systems and various coupled beams. It is shown that the minimization of the displacement of a parallel system determined from Castigliano’s second theorem can be used to formally define the apportionment of loads among the system elements, while the minimization of the lo...

recently, a large amount of studies have been related to nonlinear systems with multi-degrees of freedom as well as continuous systems. the purpose of this paper is to optimize passive vibration absorbers in linear and nonlinear states for an euler-bernoulli beam with a nonlinear vibratory behavior under concentrated moving load. the goal parameter in the optimization is maximum deflection of t...
