In pseudo dynamic test, mass of the model structure was still inputted by 100 percent, and using EL-centro earthquake wave (N-S), it was inputted by maximum acceleration value of 50gal, 100gal, 200gal, 400gal and 800gal respectively until yielding of the model structure.
For comparative analysis of every kind of seismic response of the model structure, EL-centro earthquake wave (N-S) curve is given as Fig.8.
As input earthquake wave in various test sections was adjusted only according to maximum acceleration value, EL-centro earthquake wave (N-S) in Fig.8 is only source record, and form of actual input earthquake wave was the same as the one in Fig.8, only the amplitude to change.

Considering that the metal Al is very easily oxidized (about 2 nm) in air, the native oxide layer will prevent the surface migration of Al atoms on the substrate, the annealing procedure which was generally used to fabricate self-assembling noble metal NPs is invalid for fabricating Al NPs arrays.
Figure 1 (a) shows schematic diagram of the Al NPs deposited Ta2O5.
Fig.1 (a) the principle of Inclinating deposition; (b) AFM picture of Al nanoparticles in the angle of 45°; (c) AFM picture of Al nanoparticles in the angle of 60°; (d) AFM picture of Al nanoparticles in the angle of 75°.
As the tilt angle increases, the averaged size of Al NPs decreases while with an increasing Al NPs density.
The sizes of the Al NPs were set as the average NPs sizes obtained by the AFM images.

Raman spectroscopy confirms the absence of the 3C-SiC polytype and shows the high Al doping of the layers.
The temperature was restricted to 1100°C when using a graphite crucible because these Al-rich melts were found to be highly reactive with graphite at higher temperature [6].
We believe that the substrate was etched by the Al-Si melt during the heating ramp up to 1200°C and the 2 min pre-growth step at this temperature.

Open-cell Al-Si foam samples were produced using infiltration casting technique.
Later, Guler et al. produced open-cell aluminum foam using lost foam casting technique [6].
In 2007, Jiang et al. [16]extended this morphology study to include the space holders’ size.
In this paper, Al-Si open-cell foams are manufactured using infiltration casting technique.
