The Implication of the American Experience in Urban Renewal
Lee, Jea-Sun ;
Architectural research, volume 6, issue 1, 2004, Pages 1~11
The history of urban renewal in America reveals many struggles to discover or theorize an appropriate approach for managing urban changes, and re-imagine the structure and function of downtowns. Although the context of downtown changes and the history of urban renewal policy between America and Korea are different, it is not unreasonable to place the attentions on urban renewal in the U.S. and draw the findings. This paper is to observe urban renewal focusing on downtown redevelopment along with the evolution of downtowns in the U.S. This paper concludes with calling for discovering theories pertaining to the structure and function of downtowns and adequate policy frameworks for managing urban changes and reorganizing the economic/social/environmental context in downtown areas. And simultaneously the logic and assumptions of downtown redevelopment policy should be based on the balance or equilibrium of the economic, social, and environmental dimensions.

Korea has many urban structures and buildings that can provide identity to its citizens as landmarks. Many of the structures and buildings have potential to become international landmarks through systematic management and conservation. Korea has not effectively utilized landmarks in urban planning and design, because there has been no systematic program and method for management or conservation of landmarks. This paper focuses on research and applicability to Korea of the system of landmarks in the United States. The study reviews literature such as published research reports, related regulations and policies, and public relation brochures. We then conducted online research including a review of related webpage and e-mail interviews. The results of this research can be summarized as follows: 1) The meanings of landmarks should be considered as important as their physical forms; 2) Modern structures and buildings, as well as historical ones should be considered and conserved as landmarks; 3) Diverse management methods should be applied to preservation and conservation according to types of landmarks; 4) Privately-owned, historically valuable properties should be considered and possibly designated as landmarks. The private owners should be given diverse incentives for proper management; 5) If a property loses its cultural value or meaning, withdrawal from the list of Historic Cultural Assets should be considered. Application of the results of this study will lead to systematic management of Korea's landmarks through reasonable rules and regulations. Furthermore, application of this research will help improve and reinforce the identity of Korean cities.
A Study on The Effect of Color and Seasons on the Interior Luminous Environments in an Atrium
Chung, Yu-Gun ;
Architectural research, volume 6, issue 1, 2004, Pages 25~30
This study evaluates the effect of colored glass on the interior luminous environments of an atrium. For the purpose, a 1/25-scale model of a one-sided atrium is made and images are taken of the interior environments under a clear sky condition. Surveys are conducted on KyungHee university students in the department of architecture engineering. The' SPSS program' is used to analyze the survey results. Frequency analysis and correlation analysis are performed. The results indicate that clear glass is the preferred type of glass in any seasons. After clear glass, green glass and blue glass are next in order of preference. The main variables that affect the interior environment are the slight changes in the thermal senses of the seasons. These variables are described through correlation analysis as 'bright', 'neat', 'warm', 'comfort', 'stable', 'active', 'static', 'elegant' and 'cool'. Also, three factors are extracted and analyzed in terms of their effect of the interior environment.
Post-Buckling Behavior of Shear-Deformable Prismatic Columns Under a Combined Load using Differential Transformation
Yoo, Yeong-Chan ;
Architectural research, volume 6, issue 1, 2004, Pages 31~42
In this research, the analysis of post-buckling behavior of prismatic columns has been performed, having flexural and shear stiffness, under a combined load of uniformly distributed axial load along the length and concentric axial load at free end by solving the nonlinear differential equation with the differential transformation technique. The buckling load at various slopes at free end of column is calculated and the results of the analysis using the differential transformation technique is verified with those of previous studies. It is also shown through the results that the columns including the shear deformation have smaller buckling loads than those for the columns excluding the shear deformation have. Through this research, it is verified that the differential transformation technique can be applied to solve the nonlinear differential equation problems, such as analysis of post-buckling behavior of columns. It is also expected that the differential transformation technique apply to various more complicated problems in future.
Elastic and Inelastic Response Spectra Considering the Nonlinearity of the Underlying Soil due to Weak and Moderate Earthquakes
Kim, Yong-Seok ;
Architectural research, volume 6, issue 1, 2004, Pages 43~49
Seismic design codes developed considering the strong earthquakes may result in unnecessary economical loss in the weak and moderate seismic area, and the importance of the performance based design considering the soil-structure interaction is recognized for the reasonable seismic design. In this study, elastic and inelastic seismic response analyses of a single degree of freedom system on the soft soil layer were performed considering the nonlinearity of the soil for the 11 moderate earthquakes scaled to the nominal peak accelerations of 0.075g, 0.15g and 0.2g. Seismic response analyses for the structure-soil system were performed in one step applying the earthquake motions to the bedrock, using a pseudo 3-D dynamic analysis software. Study results indicated that it is necessary to consider the nonlinear soil-structure interaction effects and to perform the performance based seismic design for the various soil layers rather than to follow the routine procedures specified in the seismic design codes. Nonlinearity of the soft soil excited with weak and moderate earthquakes also affected significantly on the elastic and inelastic responses due to the nonlinear soil amplification of the earthquake motions, and it was pronounced especially for the elastic ones.

Architectural research, volume 6, issue 1, 2004, Pages 51~57
Deformation characteristics of H-shaped beams with T-stub connections are investigated for the effect of these joints on inelastic behavior of the beams in this paper. T-stub can show semi-rigid or behavior which is close to rigid connections, making it possible to adjust the ultimate load and deformation ability. This research is applied the model of exponential function based on the equations of equilibrium and compatibility equations at the location of bolts. It is not considered that the prying action reducing both the ultimate load capacity and the fatigue of the bolts in this study. The elasto-plastic behavior has been studied through various model with parameters of the diameter of bolt, span of beam, the thickness of T-stub web, the size of flange and the web of the beam. The results indicate that the thickness of T-flange has a great effect on the ultimate strength and deformation capacity of T-stub connections. The presented method may be an useful tool for the design of T-stub connections.
