The dynamic response of the composite soil nailed wall is analyzed and discussed under the EL-Centro and man-made Lanzhou accelerogram.
Sherif Hanna, Ilan Juran et al. have studied the design of the soil nailing structure in the earthquake areas [3].
Vucetic M, Tufenkjian et al. have completed a series of centrifuge model test of soil nailing through inputting different levels of vibration model for studying antiseismic capacity[5].
EL－Centro seismic horizontal and vertical excitations are shown in Figure 2 and 3.

Kim et al. [16] studied the effect of 0.4 wt.% Sc in Al–8.5 wt.% Si alloy and observed a 60% increase in the tensile strength and a 50% increase in EL due to Sc addition.
Moreover, the addition of TiB2 has almost no effect on the UTS while it has a great effect on the EL.
Without the addition of Sc content, the UTS and YS are 298.33MPa and 169.67MPa respectively, while the EL is 6.8%.
The ductility of fracture surface of alloy is persistent with its high EL as shown in Fig. 13.
Overall, 0.5 wt.% Sc with AlSi10MnMg-T2 alloy possesses higher strength and EL simultaneously.

We studied the EL of this
diode at high injection (10kA.cm-2) (Fig 1).
The blue free-to-bound luminescence is due to Al acceptors and N donors [7].
None of the diodes exhibited any change in the IV curves neither on the EL analysis, these diodes look like free of defects.
The EL images under forward bias confirm the importance of etching conditions.
Moreover, as was shown by Sumakeris et al., SFs can emanate from a polish scratch on the surface, a scratch made by a tip or by a wire bounding.

The effect of increasing the Mg content is well known and has previously been reported by Apelian et al.,[6] Ravi et al.,[7] and Kashyap et al.[8].
Iron and Mn were added in the form of Al-25%Fe and Al-25%Mn master alloys, respectively.
For Mg-content 319 alloys, the solution heat treated (SHT) condition show the highest elongation (El %).
This is in agreement with Samuel et al [11].
Magnesium content, Sr- modification and Aging parameters (Temperature and Time) to acquire an understanding of the effects of the variables and their interactions on the yield strength (YS) at 0.2% offset strain, ultimate tensile strength (UTS), and fracture elongation (El%) of Al-Si Mg-Cu 319 alloys.
