Classical bending theories for beams and plates can not be used for short, stubby beams and thick plates since transverse shearing effect is excluded, and ordinary theories with multiple generalized displacements can not be used for long, slender beams and thin plates since the innate relation between rotation angle and deflection is ignored.

In this paper the dynamical calcalation for the composite steel-concretebeams with surface layers of non-equal thicknesses are accomplished, these results areindicated, it is very necessary that shear deformation influence and truning inertia effectare considered.

Compared with glass fiber reinforced plastics(GFRP) beams of the same section,the bending rigidity of HFRP beam,which is reinforced in the flanges with the carbon fiber,increases obviously,but the ability to resist the transverse shearing distortion doesn't increase.

A conclusion is drawn that the influence of transverse shearing distortion must be considered when the deflection of the fiber reinforced ash plastic beam was calculated.

As to the application of the box-girder with corrugated steel webs in China now,the flexure curve e-quation of cantilever box-girder with corrugated steel webs was educed based on Timoshenko beam theory that deflection was affected by transverse shearing distortion.

The transverse shear deformation effect is included by use of Mindlin-Reissner first-order shear deformation theory.

The transverse shear deformation effect was included by using the Mindlin-Reissoner first-order shearing deformation theory.

Also, the formulation accounts for transverse shear deformation effects of the plate and stiffener in terms of Mindlin hypothesis, and a interpolation for revising membrane strains and transverse shear strains is used to overcome ‘locking’ behavior.

Displacemental vibration equations of thick shells of revolution considering transverse shear deformation;

Tn this paper, equations of motion of axisymmetrically laminated cylindrical orthotropic spherical shells are derived with consideration of the transverse shear deformation and rotatry inertia On this basis, using the finite difference method, the dynamic response of spherical shells under axisymmetric dynamic load is calculated.

This paper compared several mechanical models with transverse shear deformation and put forward a kind of layer model assuming that shear stresses vary parabolically through the plate thickness.
