Katona et al. [3] has developed a software program named CANDE to incorporate the seismic effect on culverts by applying a free field displacement boundary condition on a finite element model.
Then the earthquake excitation is input in the lower boundary and the EL-CENTRO acceleration time history is adopted to be the excitation history with its duration of 10 seconds, sample interval of 0.02 second and peak acceleration of 0.1 g.

Experimental results have shown that diagonally reinforced coupling beams are capable of maintaining their shear strength with good stiffness recovery and energy dissipation under large displacement (Paulay and Binney 1974; Shiu et al.1978; Tassios, Moretti, and Bezas 1996; Galano and Vignoli2000).

These are nano particles of high melting point compounds, typically carbides, nitrides, carbonitrides, oxides (B4C, SiC, TiCN, TiN, TiC, AlN, TaN, Y2O3, and others), whose surface is covered with metals-protectors (Cr, Fe, Al, Cu, and others).
