According to influence of pile groups of high-rise buildings on metro tunnels nearby, the research is made to analyze the stress of soil and the settlement of neighboring tunnels caused by pile groups. Based on the hypothesis of pile groups under flexible cushion cup, the plain strain of profile of tunnels is calculated by combining the load spreading property along over-length piles and Mindlin answer and the formula of displacement field of soil. In this way, MATLAB programs are made to get some useful conclusions by analyzing the influence factor of the settlements of tunnels such as the distance between them and the collocation of piles, the loading level and the scale of piles.

Coupled Shear Wall

In the last several decades, coupled shear wall have become recognized as efficient lateral load resisting systems for high-rise structures, increasingly. Coupled shear walls give considerable lateral stiffness and strength as well as providing an architecturally practical structural system. In this paper, in order to observe seismic performance of coupled steel plate shear wall, models of previous study was verified, and coupled shear wall with steel plate was carried out with various parametric analysis. Parametric analysis was performed with various width of bay. As a result, model that aspect ratio of steel plate was close to 1 was the most structurally safe.

With the increasing possibility of large offshore earthquakes in Japan, the government is considering whether middle to high-rise structures could be used as temporary tsunami refuge buildings. This report presents a recent study on refuge-process modeling within such buildings and their utility seen through parametric analysis. Analysis showed a strong dependence of refuge effectiveness on the time when evacuation start and building occupancies. Design guidelines are proposed to improve evacuation performance for different types of occupancy.

To accommodate the shear requirement and settlement requirement of high rise construction, the concept of piled-raft foundation has been developed. This research deals with successive analysis of parameters of piled-raft foundation system using PLAXIS-2D as a FEM tool. Plain strain analysis of piled raft foundation system has been conducted out by successive fixing up of parameters. For the analysis two cases has been studied for piled-raft lying on silty soil deposit and on clayey deposit with respect to uniform static loading from superstructure. The result of successive variation of parameters showed that variation has limiting effect on stress and displacement behavior. The analysis is also performed for raft of different relative stiffness and pile of different relative compressibility and load sharing between plain strain pile and raft has been analyzed.

Symmetry Criterion

The invisibility criterion which is the standard technique for determining the nature of dislocations seen in the electron microscope can at times lead to erroneous results or at best cause confusion in many cases since the dislocation can still show a residual image if the term is non-zero, or if the edge and screw displacements are anisotropically coupled, or if the dislocation has a mixed character. The symmetry criterion discussed below can be used in conjunction with and in some cases supersede the invisibility criterion for obtaining a valid determination of the nature of the dislocation.The symmetry criterion is based upon the well-known fact that a dislocation, because of the symmetric nature of its displacement field, can show a symmetric image when the dislocation is correctly oriented with respect to the electron beam.
