The design of a jacket structure is highly dependent on target environmental variables. This study focuses on a strategy to estimate design loads for offshore jacket structures based on an environmental contour approach. In addition to the popular conditional distribution model, various classes of bivariate copulas are adopted to construct joint distributions of environmental variables. Analytical formulations of environmental contours based on various models are presented and discussed in this study. The design loads are examined by dynamic response analysis of jacket platform. Results suggest that the conditional model is not recommended for use in estimating design loads in sampling locations due to poor fitting results. Independent copula produces conservative design loads and the extreme response obtained using the conditional model are smaller than those determined by copulas. The suitability of a model for contour construction varies with the origin of wave data. This study provides a reference for the design load estimation of jacket structures and offers an alternative procedure to determine the design criteria for offshore structures.展开更多

In this study, it was found that the main type of foreign crime that occurred in the research area was violence, and crimes committed by Koreans, which were mainly violence and crimes such as burglary, theft, robbery, and sexual offences, occurred steadily. Because it was found that crimes were related to the urban planning elements comprised of land use such as traditional market, inn, pub, and complicated space structure and the architectural design for natural surveillance and security facilities such as CCTV, lighting, alarm, and target hardening device, a new strategy for crime prevention design should include street environmental management, improvement of commercial facilities, and reinforcement security device of each buildings has to be spread through support of policy. In conclusion it was thought that CPTED would be a valuable measure to prevention crime and support community activities in ethnic area as expecting an improvement of physical environment and resident participatory for safer community.展开更多

The proposed procedure considers the combined effect of tide level, huge waves and wind affecting coastal structures. The Importance Sampling Procedure (ISP) is utilized to solve the joint distribution of non Gaussian correlated multivariate distributions. The calculation results show that the ISP is a simulating technique with the advantages of efficiency and high convergency.
