BENDING-SHEAR TESTS OF WIDE FLANGE STEEL BEAM USING THE BOLTED FRICTIONAL-SLIPPAGE DAMPER ON THE BOTTOM FLANGE AT THE BEAM END In this paper, we proposed a new seismic hinge, which was applied to the beam end regions of steel moment resisting frame structures. The hinge consists of... T ...
The deformation of components increased under the affects of external loads. Therefore, in order to improve the accuracy of finite element analysis model, by consideration of the shearing effects and the bending stiffness affected under opened structure, this issue made improvement based on theory of...
Extension, torsion, and bending of a bernoulli-euler beam The exact axial, bending, and torsion stiffness matrices have been developed for an arbitrary nonuniform beam element. The coefficients of the bending stiffness matrix require the evaluation of three integrals, while the axial and torsio......
A new beam element with a crack is proposed, and its dynamic stiffness matrix is derived by using the line-spring model in fracture mechanics. 提出了一种含裂纹的杆单元,基于断裂力学的线弹簧模型,导出了相应的动刚度矩阵。 2. The internal forces and displacements of the frame-shear wall structur...
2015). Some testing was performed to understand the change in anisotropy as a result of printing in an annealing chamber, but sample sizes were small and three-point bending fixtures instead of four-point bending fixtures were utilized (Klein et al. 2015), which we return to discuss for ...
The unit is equipped with 7 oil-film bearings, which are modelled by their linearized stiffness and damping coefficients. The supporting structure is modelled by means of simple pedestals. Let us now examine the static bending moment distribution along the shaft-line with reference to this typical...
pink area of the quad-domain with an in-plane component of [\(\bar{1}\bar{1}0\)]-oriented polarization grows, but the gray area of the quad-domain with an in-plane component of [\(\bar{1}10\)]-oriented polarization shrinks. This domain evolution is accompanied by DW bending (Fig...
A nonlinear dynamical model of bending–torsion coupling vibration induced by multiple excitation vibration sources of the shafting system is established in the first stage. The multi-stage signal denoising method combines Savitzky–Golay (SG) smoothing filtering, singular value decomposition (SVD), and...
Figure 2. Hierarchical overview of the product architecture of eBikes and relevant influences on the DU, according to [2]. eBike-system-dependent parameter like the frame stiffness, mounting angle and geometry of the crankset and chain blade. DU-dependent design parameters like the geometry and...
