  • This is a comparative study mainly on foreign countries' domestic standards and laws on barrier free housing construction that can be applied to the dwelling of elderly friendly apartment housing. Eight countries - the United States, Germany, Canada, Switzerland, the United Kingdom, Australia, Japan, and China - were reviewed as foreign cases. The analyzed subjects were design standards only for the disabled and the aged. To compare barrier-free guides of the eight countries, each barrier-free guide on three space units (entrance, bedroom, living room) was divided into 11 design items and 36 design factors. The comparative analysis on foreign cases was based on the design guide according to Korea's KS P 1509 (principle and recommendation for designing dimension of dwelling in consideration of the elderly). Some factors -if with dimensions- were compared by means of the skewness of distribution. In the analysis result, there were not only common standards for the nine countries such as a dimension of the space for wheelchair movement but also different standards such as heights of outlets and horizontal lengths of bathtub grab bars. The detailed analysis shows that it is urgently necessary to prepare new domestic national design standards for 8 factors that foreign countries already have. It is also needed to immediately prepare dimension standards for the design factors, which have no detailed dimensions but only national guides, in consideration for anthropometric dimension.

  • In the present paper, the fiber theory has been employed to model the reinforced concrete (RC) deep beams (DBs) considering the reinforcing steel bar-concrete interaction. To simulate numerically the behavior of materials, the uniaxial materials' constitutive laws have been employed for reinforcements and concrete and the bond stress-slip between the reinforcing steel bars and surrounding concrete are taken into account. Because of the high sensitivity of DBs to shear deformations, the Timoshenko beam theory has been applied. The shear stress-strain (S-SS) relationship has been defined by the modified compression field theory (MCFT) model. By modeling about 300 RC panels and employing a produced numerical database, a study has been carried out to show the sensitivity of the MCFT model. This is performed based on the multiple linear regression (MLR) models. The results of this research also illustrate how different parameters such as characteristic compressive strength of concrete, yield strength of reinforcements and the percentages of reinforcements in different directions get involved in the shear behavior of RC panels without applying complex theories. Based on the results obtained from the analysis of the MCFT S-SS model, a relatively simplified numerical S-SS model has been proposed. Application of the proposed S-SS model in modeling and analyzing the considered samples indicates that there is a good agreement between the simulated and the experimental test results. The comparison between the proposed S-SS model and the MCFT model indicates that in addition to the advantage of better accuracy, the main advantage of the proposed method is simplicity in application.

  • Space extension and the increase of the number of households are helpful to raise business value of the remodeling through the renovation of apartment houses that is required by residents of new cities and large-scaled apartment. However, in the case of accepting this demand, it could have a bad influence on the landscape of a complex in terms of the structure of apartment houses and the safety of construction and urban planning, and a problem occurs in the aspect of fairness for reconstruction. For the study, the current status related to the remodeling system through laws, related articles since 2000 and research data was analyzed. In addition, the individual quantitative analysis was conducted in the four aspects to judge whether households expansion for remodeling is plausible:1) Statistical data to comprehend the changes of population and social structure 2) Survey data of floor space index and the building-to-land ratio of new cities at the intial stage for the review of the effect of architectural planning and urban environment 3) Surveys of experts on structural safety in order to judge whether the demand of expansion is accepted or not. 4) Quantitative analysis of each item to compare fairness with reconstruction. Therefore, this study is intended to understand problems of the remodeling system that is currently operated. Moreover, it will be further reviewed that the expansion of households is feasible through the permission of expansion and it will be discussed that the revitalization of the apartment remodeling has a positive impact on the residential environment.

  • The railway crossing is very dangerous because the track intersects with the road there. Thus, The laws were designed for safety of the railway crossing and they are classified as to the acts for the road and the railroad. For safety of the railway crossing, there are 'Road/Railroad Crossing Improvement Promotion Act', 'Enforcement Decree of Road/Railroad Crossing Improvement Promotion Act', 'Rules on Construction of Railroad', 'Rules on Safety Standards of Railroad Installations', and 'Enforcement Ordinance of Cable way/Railway Track Act' in the acts for the railroad and there are 'Road Traffic Act', 'Enforcement Ordinance of The Road Traffic Act', 'Ruled on Structure and Facility Standards of The Road', 'Rules on Structure And Facility Standards Of The Rural Road' and 'Rules on Structure and Facility Standards of The Installations for Bicycle' in the acts for the road. Both the acts for the road and the railroad have standards for the structure of the railway crossing. However, they have different standards. Besides, they don't have standards for new facilities which were recently installed for safety of the railway crossing. Therefore, we suggest new standards for safety of the railway crossing.

  • Coarse-grained soils are typical engineering materials commonly used in many civil engineering applications such as structural fills, subgrade and drainage fills for dam, railway and bridge. Various researches have been performed with related to constitutive laws for numerical analysis of such structures. This paper presents a parametric study for a constitutive model for coarse grained materials. The model is a kind of the bounding surface models based on critical state theory. A distinct feature of the model is to capture the response of coarse-grained materials with different void ratios and confining pressures using a single set of model parameters. The model behavior is defined with a set of elastic parameters, critical state parameters, and model-specific parameters. The parametric study was performed for the model-specific parameters. The result of parametric study shows that the model is capable to capture stress-dilatancy behavior and kinematic-hardening under non-associative plastic flow.

  • It is possible to evaluate hi-tech spatial services such as U-City services as part of the visible results from more than 10 years of public efforts and budgets on Korea National Digitalization. The U-City services are mainly based on ICT(Information and Communication Technology), but in the aspect of giving intelligence to the existing physical space, in principle, they are to be inter-connected with both spatial information and spatial plan. But, still there are few shared concepts for linking U-City services with spatial information and spatial plan. Therefore, under the proposition of the realization of Ubiquitous National Territory in the Digital Convergence Era, the purpose of the current study is to facilitate the balanced development among U-City services, national spatial data and spatial plan by proposing a new concept of Digital Convergence Space. Then, for its realization, regarding laws and policy arrangements are suggested.
