The purpose of this study is to analyze the architectural space of modern and contemporary architecture which has been changed by the aesthetic cognition on space. The intention of considering architectural space aesthetically is to convert the viewpoint of seeing space as simple physical structure into different viewpoint of regarding 'space' as 'cultural place' However this does not means to apply aesthetic theory to architectural space. The aesthetic cognition on space is one of the main subjects of the expression of art from ancient to today however the appearance of space concept as architectural aesthetics accelerated by G. Semper theory after the latter half of 19th century. On the standpoint of perpetuity in architecture the aesthetics of scientific rationalism in modernism based on the reasonable thinking regards the variety of inherent characteristic in architectural space as 'Transferential Space'. On the other hand, in regarding to architectural trend, the nature in architectural space has been considered as 'Existential Space' starting from the conscious construction of environments to help human existence in the existentialism. The Conclusion logic of follows as belows; first, the concept of space structure in architecture has been exchanged from Enclosed Space to Topological Space. Second, the concept of architectural space has been changed and developed to the Deterministic, Profound, Dissipative, and Recognizable Space according to the change of expression in architecture.

Based on the random cracking theory, the cylinder RVE model of reinforced concrete is established and the damage process is divided into three stages as the evolution of the cracks. The stress distribution along longitude direction of the concrete and the steel bar in the cylinder model are derived. The equivalent elastic modulus of the RVE are derived and the user-defined field variable subroutine (USDFLD) for the equivalent elastic modulus is well integrated into the ABAQUS. Regarding the tensile rebars and the concrete surrounding the rebars as the equivalent homogeneous transversely isotropic material, and the FEM analysis for the reinforced concrete beams is conducted with the USDFLD subroutine. Considering the concrete cracking and interfacial debonding, the macroscopic damage process of the reinforced concrete beam under four-point bending loading in the simulation. The volume fraction of rebar and the cracking degree are mainly discussed to reveal their influence on the macro-performance and they are calibrated with experimental results. Comparing with the bending experiment performed with 8 reinforced concrete beams, the bending stiffness of the second stage and the ultimate load simulated are in good agreement with the experimental values, which verifies the effectiveness and the accuracy of the improved finite element method for reinforced concrete beam.

A methodology for design of reinforced concrete members for serviceability in general and deflection control in particular is presented based on application of utility theory. The approach is based on minimizing total cost including both initial construction and cost of failure considering variability in structural behavior and various forms of serviceability loss function. The method is demonstrated for the case of a simply supported slab for example.

This paper investigates morphological theory as an intellectual framework for research and design. The first part of the paper will review morphological studies in the fields of urban geography, urban planning and architecture, particularly in England from the 1940s to the 1980s. While urban geographers and planners were concerned primarily with town plans, building forms and land use, architectural theoreticians were more interested in the topological relationship between urban and architectural space. The underlying premises and principles of these two approaches will be reviewed. The second part of the paper will focus on typology in Europe and North America. The reinterpretation of typology by Italian architects helped to bridge the gap between individual elements of architecture and the overall form of the city. However, typological theory became less accessible in post-war England and the United States. After 1980, the debate on typology became muted by the onset of vague notions such as functionalism, bio-technical determinism, and contextualism. This paper will propose a redefinition of morphology as a heuristic device, in contrast with the dichotomic view of urban morphology and architectural typology. Morphology will be shown to combine the geometrical and topological; the intentional and accidental; the real and abstract; and a priori and a posteriori. The last part of the paper discusses the lack of comparative theories and methods surrounding the physical form of architecture and the city by Korea commentators. Empirically rooted facility planning, non-comparative historical studies, and iconographic criticism emerged as a central preoccupation of architectural culture between the 1960s and 1980s, a time when international debate on architecture and urbanism was most intense. This paper will give consideration to the built environment as a dynamic physical entity and space as an epiphenomenon of daily urban life, such that collaboration between urban designers, architects, and landscape architects is seen as both beneficial and necessary.

The purpose of this paper is to apply Stephen C. Pepper's contextualism to architecture: to interpret the former in the light of architectural theory, and ultimately to liberate architecture from the Western 'Idea' and return it to its context. The major concepts of Pepper used in the paper are quality, texture, spread, change, fusion, strand and context. Pepper's contextualism makes us realize that architecture cannot be separated from its context where human beings, history, neighborhood, and nature are all interpenetrating, and create a quality. Contextualism thus teaches us to make an effort to understand the region where we belong, and to create an architectural device that interrelates form and function of an architecture with its space-time environment, or its strand, texture and context.

Alois Riegl's aesthetic theory of visual perception provided one of important conceptual backgrounds for Vienna Art Nouveau architecture. Riegls theory of visual perception consists of geometric style and two-dimensional transformation. Riegl's theory of geometric style is based on the modern aesthetic theory of abstraction, which says that the artistic perfection can be obtained not from a direct imitation of natural objects, but from an abstract transformation of them. Riegl's theory of two-dimensional transformation, on the other hand, aims at obtaining artistic perfection by disintegrating volumetric conditions of natural things into planes and combining the planes thus obtained into another new world of art. These two theories of Alois Rigl's provided an important aesthetical background for the design strategy of 'abstract ornamentaion of two-dimension' in Vienna Art Nouveau architecture. This paper is to review the basic concept of Alois Rigl's theory of geometric style and two-dimensional transformation.

This study covers centrality of villas after Renaissance and architectural forms corresponding to the nature in the aspect of Karl Popper and Gilles Deleuze. In addition, the researcher tries to understand the changes in architectural forms according to the changes in places. To do that, Pascal and Hans Meyer's theory was introduced as a major theory. The researcher tries to set up the standard by analyzing the architectural form related with the nature and the form of center in the housing through Villa Rotonda and Villa Emo. And with key analysis of the centrality and architectural form corresponding to the nature and the four houses that are historically and morphologically important. It is found that due to the development in modern technology and materials, a variety of architectural approach is developed and they are implemented as various architectural forms. However, due to various theories of modern architectural approach, it is found that the morphological differences of suburban housing exists by forming a universal relationship constructed by four architects. The researcher expects to be understood and realized in real life construction.

Science, technology and machine aesthetics were the main theme of architectural design in the first machine age. Modern architecture used the theory of science as its framework. But the theory of science was used not as a professional way, but as a pseudo-scientific way by modern architects. It was because that modern architects relied on the spiritual, mystical realm of science and mathematics. Moreover, the avant-garde movement in modernism used the theory of science and mathematics for its complicated and ailenated nature and scientific image. The pseudo-scientifism in architectural design in the first machine age was expressed mainly as a concentration on the 4th dimensional space and the use of symbolic image of science and technology.

According to previous studies, the form of a city mentioned in Kaogongji(考工記) of Zhouli(周禮) does not exist in reality. Only Beijing during Ming(明) and Qing(淸) Dynasties is discussed as an example, making it lose its worth as a theory. But of all the annotation of Zhouli throughout the 2,000 years before the modern era, core theory related to capital construction had never been stated from the aspect of the present day. Such discussion can be found depicted in Yingzaofashi(營造法式), a specialized book about architectural technology. Unlike what is known until now, the principle of capital construction has a link to the theory of Fengshui(風水), in that it implies the logic of 'Yi(易)'.

The size-dependent behavior of single walled carbon nanotubes (SWCNT) embedded in the elastic medium and subjected to the initial axial force is investigated using the mixed finite element method. The SWCNT is assumed to be Euler-Bernoulli beam incorporating nonlocal theory developed by Eringen. The mixed finite element model shows its great advantage of dealing with nonlocal behavior of SWCNT subjected to a concentrated load owing to the existence of two coefficients ${\alpha}_1$ and ${\alpha}_2$. This is the first numerical approach to deal with a puzzling fact of nonlocal theory with concentrated load. Numerical examples are performed to show the accuracy and efficiency of the present method. In addition, parametric study is carefully carried out to point out the influences of nonlocal effect, the elastic medium, and the initial axial force on the behavior of the carbon nanotubes.
