Abstract.
Random arrangement is suitable for the workplaces where it is not possible to determine the plant situated material flow, the continuity of operations, or organizational and management relations.
It is used in single and small batch production, where the diversity of produced parts impossible to unite the direction of material flows.
Material flow of the product has the same direction.

The mechanical properties of the soil and the other materials were described in Table 1.
The authors made some simplification in this finite element model: (1) Soil layers were homogeneous, and horizontal level distribution. (2) The soil material behavior was assumed to be governed by an elasto-plastic constitutive relation based on the Druck-Prager criterion. (3) The influence of groundwater was not taken into consideration.

Several types of
supporting materials have been investigated, like silicone [13], polystyrene [14], silica gels [15],
ethylcellulose [16], etc, and mixtures of some of these materials [17].
It was found that, in general, sol-gel materials present much higher solubility.

Abstract:With the purpose of comprehending the seismic performance of steel-braced frame system better and more comprehensivly, the paper overviewed and summarized the hysteretic performance,ductility and energy dissipation performance of the steel-braced frame based on a large number of abroad documents.The force was on the seismic performance of steel-braced frame in different supporting forms and the insufficiency in the research.
Pseudo dynamic test.Pseudo dynamic test was an online test that combined the loading system with the computer .By pseudo dynamic test,we could analyzed the load feedback, acceleration and displacement reaction, the changing process of strain of the steel frame.It was beneficial to analyze the elastic-plastic stage performance,observe the change of structural performance and could carry out the seismic test for large size specimen .However it couldn't reflect the effect of material strain rate on the structure and the actual circumstances of undertaking the force distribution.
