The modal slope is fitted by two Fourier-series functions, one of which is derived from a thin-beam model. The local bending stiffness is identified as the one corresponding with the best match between the measured and the two fitted modal slopes. This identification method, which we call ...
Compared to RC beam, the bending stiffness of the strengthened RC beam is boosted with about 6 percent. 与普通钢筋混凝土(RC)梁相比,碳纤维薄板增强RC梁屈服前的刚度提高了6%左右。 epub.cnki.net 4. The optimal axial and bending stiffness were computed to reduce the spinal motion by 30%. 通过计...

The model test was carried out to research the bending stiffness of longitudinal segment joint. The following conclusions are obtained:( 1) the curve of the bending stiffness of segment joint is a highly nonlinear and non-monotonic functions whose slope is difficult to be expressed.( 2) The bi...

The resulting effects of shear stiffness of the Pasternak model on the mechanical quantities are discussed in comparison with those of the Winkler's model. Some numerical case studies illustrate the accuracy of the formulation and the importance of the soil shearing effect in the vertical direction,...
where (EI)s, is the bending stiffness of the two steel plates. The total bending moment is then M=Mt+Ms=1R[(EI)t+(EI)s] This gives (11.2)1R=M(EI)t+(EI)s Clearly, the beam behaves as though the total bending stiffness El were (11.3)EI=(EI)t+(EI)s If Et and Es are the...

Differential quadrature method is employed to study the elastic and elasto-plastic bending of beams with arbitrarily variable stiffness. The influence of variable stiffness on the elastic and plastic performances of the beam is discussed through numerical examples. 展开 ...
Biomimetic scales provide a convenient template to tailor the bending stiffness of the underlying slender substrate due to their mutual sliding after engagement. Scale stiffness can therefore directly impact the substrate behavior, opening a potential av
