The research described in this paper investigates the seismic behaviour of lightly reinforced concrete (RC) bearing sandwich panels, heavily conditioned by shear deformation. A numerical model has been prepared, within an open source finite element (FE) platform, to simulate the experimental response of this emerging structural system, whose squat-type geometry affects performance and failure mode. Calibration of this equivalent mechanical model, consisting of a group of regularly spaced vertical elements in combination with a layer of nonlinear springs, which represent the cyclic behaviour of concrete and steel, has been conducted by means of a series of pseudo-static cyclic tests performed on single full-scale prototypes with or without openings. Both cantilevered and fixed-end shear walls have been analyzed. After validation, this numerical procedure, including cyclic-related mechanisms, such as buckling and subsequent slippage of reinforcing re-bars, as well as concrete crushing at the base of the wall, has been used to assess the capacity of two- and three-dimensional low- to mid-rise box-type buildings and, hence, to estimate their strength reduction factors, on the basis of conventional pushover analyses.

The purpose of this study was suggested to establish of student housing by using shipping container. The research method are a study of shipping container and characteristics of student housing by using shipping container, compared typically student housing with student housing by using shipping container. Also there are planning though a case study of various planes and survey based on the student housing city in Amsterdam, Netherland, is called Keetwonen. It is a planning for housing unit to actual build at the part of land to devise master plan The 40FT(High Cube) Shipping Container housing unit are double occupancy room with toilet and balcony. The common areas are the kitchen, laundry facilities, conference room and lounge are available on the first floor with a lightweight steel frame construction method applied for obtain substantive utilization of the space. Considering into the type and scale of site shall be planning in the form of side corridor and central corridor, which is preferable to separate the interior space into two areas by a central corridor to secure personal privacy. Also, planning such as a separate exterior panel, color and landscape design to improve the external image of the container and block the solar radiation heat influx with a pitched roof. Allow 24 college students shall live at the site of Seongnae-dong, Gangdong-gu in Seoul, Korea (site area $330.9m^2$), including common facilities and a lounge with a building that has three stories above ground were established to build plans to target the actual land.
