In the present paper, effect of initial stresses on the propagation of Love waves has been investigated in a fluid saturated, anisotropic, porous layer lying in welded contact over a prestressed, non-homogeneous elastic half space. The dispersion equation of phase velocity has been derived. It has been found that the phase velocity of Love waves is considerably influenced by porosity and anisot...

<p>The reduction of the structural capacity and eventual collapse existing concrete bridges is often related to loss initial prestressing forces. This can be associated immediate or time dependent factors such as elastic shortening, creep, relaxation, loading, cracking, among others. In addition, environmental lead corrosion strands with subsequent their area, bond additional cracking whi...

Abstract The combination of low clinker high-performance concrete (LCHPC) and ultra-high modulus (UHM) carbon fibre reinforced polymer (CFRP) tendons was recently proposed for prestressed structural elements. 70% reduction in cement content resulting limited creep shrinkage the LCHPC comparison to a conventional (HPC) very high UHM-CFRP tendon stiffness (> 509 GPa) were expected impact mecha...
