Behavior of Beam with Fiber Reinforcement under Alternating Loads

Analysis of a Beam under Moving Loads

Abstract: It is assumed that a beam made of material has a physical nonlinear behavior. This beam is analyzed under the moving concentrated and distributed continuous loads. The vibration equations of motion are derived from the Hamilton's Principle and Euler–Lagrange Equation. In this study, the amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam has b...

Reinforcement of Glass Ionomer Cement: Incorporating with Silk Fiber

The aim of this study was to synthesis of glass ionomer-silk fiber composite and to evaluate the effect of adding natural degummed silk fiber on the mechanical properties of glass ionomer cement (GIC). For this purpose, natural degummed silk fibers with 1 mm in length and 13-16 µm in diameter were added to the ceramic component of a commercial glass ionomer cement in 1, 3 and 5 wt. %. Compressi...

Behavior of Composite Timber-Concrete Beam with CFRP Reinforcement

Damage Detection of Bridge Beam Structures under Moving Loads

System identification technique is used widely in the damage assessment of engineering structures. It is regarded as the key part of a structural health monitoring system, which identifies the physical parameters from the raw measurement data. The changes in the identified parameters will be used to assess the damage of the structure. Most system identification methods need the input loading an...

Shape optimization of reduced beam section under cyclic loads

Optimal shapes are found for reduced beam section of a cantilever H-beam subjected to forced cyclic displacement at the free end. The beam is discretized to finite elements, and a commercial software package called ABAQUS is used for elastoplastic analysis. The numerical results are first compared with experimental results to verify the accuracy. The objective function to be maximized is the di...
