continuous beamplastic propertiesTo study the plastic properties of reactive powder concrete continuous beams reinforced with GFRP bars,the calculation programs for moment redistribution coefficients are prepared by using nonlinear analysis methods such as moment-curvature,conjugate beam method and so on. By...
A mass at high speed traversing a uniform, horizontal, continuous beam resting on discrete supports gives rise to critical beam deflection and bending moment responses greater than those for the mass traversing at crawl speed. It is shown herein that these responses are significantly reduced by the...
The reasonable lower limit value of side-to-mid-span ratio of upper flying bird style beam- arch composite bridge is controlled by side-span reaction force, and its reasonable upper limit value is controlled by negative bending moment of arch ring in bifurcation zone, and its reasonable range ...
One of the critical elements in continuous girders is the beam-to-beam joint, characterized by negative bending moment, which induces tensile stress in concrete decks and compression in the lower flanges of steel beams, thus influencing the bridge’s durability and lifespan [2], [3]. 1.1. ...

and moment unbalance. An unbalance equal to a force of 5% of the rotor weight is usually applied at the coupling to excite the rotor. For moment unbalance, an unbalance equal to 5% of the rotor weight is used at the coupling and another equal unbalance is used out-of-phase on the impel...
materials to capture energy from ultrasound. The piezoelectric effect is the energy generation in some solid materials due to mechanical stresses due to changes in its dipole moment. This can be obtained through the implantation of ions or the presence of asymmetrical charges on the material's ...
The continuous beam-arch bridge is a special kind of bridge structure that consists of two structural systems, the beam bridge and arch bridge. It applies the girder’s axial force organically to balance the arch’s horizontal thrust. The structure’s total bending moment is represented in the...
The transverse displacement y(x,t) of a beam segment can be obtained by solving Eq. (1), in which m, E, I, v, ce and cs refer to linear density, elastic modulus, moment of inertia of the beam section, velocity of moving load, external damping and internal damping of the system, ...
The natural frequency is dependent on the variation of the stiffness coefficients due to the crack. The frequency response and the orbit of the shaft in the cross-section of the disk are also calculated for variable crack depths. The aim is to show the differences in the dynamic properties ...
