Reinforced Earth Wall Design What Is The Difference Between Static, Pseudostatic And Pseudodynamic Analysis In Retaining Wall Designs?

Pseudo-static and dynamic nonlinear finite element analysis was conducted to evaluate the dynamic behavior of the gravity of the walls subjected to horizontal earthquake load. In the pseudo-static analysis, the maximum acceleration of the earth becomes a pseudo-static inertia force is applied as a horizontal load progressive severity. In the dynamic analysis of an acceleration of the earthquake history was measured in real time enhanced to provide the maximum acceleration of the Earth 0.1 g and 0.3 g. They received a good agreement between the pseudo-static analysis and analytical methods for calculating the pressure coefficient of active earth. However, the results need careful interpretation of the dynamic test. In the pseudo-static analysis, the increase in the number of active application of the resultant force with the horizontal seismic coefficient KH-third point of the half height of the wall is clearly visible. In the dynamic analysis, the variation of the application site shown as a function of strain rate on the wall. Both the finiteement analysis shows the importance of determining the extent of displacement is in evaluating the performance of the seismic loading of the wall.

What do I get from static analysis of computer code to lol with the walls, but static, since they were still up .. or the database can idk.
