Based on a realistic consideration of mobilization of interslice shear forces, the limitations of interslice shear force equation in Sarma s method are analyzed in this paper.

It is shown that the stiffness,interstory shear force and axial column force increase in steel bracing system,and the internal forces decrease in the energy dissipation system under the condition of the same displacement.

It is shown the stiffness and the interstory shear force and the axial column force which is connected with the bracing are increased in steel bracing system and the internal forces decreased in the energy dissipation system when their displacements are controlled almost the same.

Effect of interlayer on shear stress between layers of PCC-AC composite pavement;

Results show that temperature turns out to be the most significant factor influencing the shearing strength between layers,next comes the diameter of bestrewed detritus,next but one is the thickness of paved ply,while the influence of.

The 3D finite element method was used to study the critical stress position,the overlay tensile stress,interface shear stress and interface normal tensile stress.
