The purpose of this study is to evaluate Aldo Rossi's work as representation or non-representation, for some hold that the works of Aldo Rossi are representative and others say that they are non-representative. According to the three kinds of novelties appearing after Stephen Pepper's concept, "the breaking of reference" happens, and Aldo Rossi's concept, "the sense of deposition" Rossi's work is uncovered as non-representation. In order to clarify Rossi's work as non-representation, we are going to borrow Pepper's terms, intrusive novelty, emergent novelty, and naive novelty. The breaking of reference accompanies intrusive novelty to bring a sense of representation, emergent novelty to intuit a sense of non-representation, and naive novelty to a sense of newness of disorder. We hope to verify a hypothesis that Aldo Rossi's architectural thought and the architecture come from 'emergent novelty' on the basis of his two books, A Scientific Autobiography and Architecture of the City. Also this paper discusses qualitative aspects rather than visual aspects. The main concepts of emergent novelty are applied to Aldo Rossi's works and his thought. Finally this paper verifies 'the hypothesis' through revealing what Aldo Rossi means by the quality of suspension, the sense of deposition, and idea of the unfinished(repetition). Rossi's work is not textural reference of representation appearing after blocking, but qualitative reference of non-representation.

In this paper, analytical models for reinforced concrete shear wall systems designed based on Korean Building Code (KBC2009) are proposed, which have special and semi-special seismic details and are compared with experimental results for a verification of analytical models. In addition, semi-special seismic details aimed to improve constructability and enhance economic efficiency were proposed and evaluated. The analytical models were performed based on nonlinear static and dynamic analysis. Through the nonlinear analyses, two seismic details showed the similar seismic behavior from the cyclic test and the analytical models for the two different seismic details represented the behavior in terms of the initial stiffness, maximum strength and strength degradation. And newly proposed seismic details(semi-special) provided with similar hysterestic behavior as well as the maximum drift.

In typical, structural topology optimization plays a significant role to both increase stiffness and save mass of structures in the resulting design. This study contributes to a new numerical approach of topologically optimal design of Mindlin-Reissner plates considering Winkler foundation and mathematical formulations of multi-directional variable thickness of the plate by using multi-materials. While achieving optimal multi-material topologies of the plate with multi-directional variable thickness, the weight information of structures in terms of effective utilization of the material at the appropriate thickness location may be provided for engineers and designers of structures. Besides, numerical techniques of the well-established mixed interpolation of tensorial components 4 element (MITC4) is utilized to overcome a well-known shear locking problem occurring to thin plate models. The well-founded mathematical formulation of topology optimization problem with variable thickness Mindlin-Reissner plate structures by using multiple materials is derived in detail as one of main achievements of this article. Numerical examples verify that variable thickness Mindlin-Reissner plates on Winkler foundation have a significant effect on topologically optimal multi-material design results.

The purpose of this study is to investigate the relationship of architectural ideology and characteristics of spatial composition between Moisei Ginzburg's Narkomfin communal house and Le Corbusier's Unite d'Habitation. Narkomfin communal house and Unite d'Habitation is considered as example of experiment to construct ideal community housing model. Moisei Ginzburg designed Narkomfin communal house to make typical housing model for socialist city. Meanwhile, Le Corbusier is considered as a leader of modern functionalism architecture. His Unite d'Habitation in Marseille is important experiment for housing model in modern period. Unite d'Habitation is known to be affected by Narkomfin communal house in terms of architectural ideology and its spatial composition. This study focuses on comparative analysis between Narkomfin communal house and Unite d'Habitation through drawings, pictures and various literatures. Narkomfin communal house and Unite d'Habitation have common ideology to realize ideal community housing model. Moreover, both of them have considerable similarities in their spatial composition. First of all, unit housing of Narkomfin and Unite d'Habitation are maisonette type. Secondly, both of them have unique system that one corridor serve two of housing unit. Also, both have common facility such as laundry, childcare which is connected with their housing.

This paper examines the Dutch policy for architecture and spatial design within the framework of the theory of creative industries. Creative industries are a young concept that emerged in the mid 1980's as a form of commercial cultural production associated with consumerism. The definition of the cultural industry is rather ambiguous in terms of its scope and its relation to the traditional field of art and cultural heritage. The paper describes the theory of the creative industry and relates the Dutch policy for architecture and spatial design to the creative industries theory. The sector of architecture and spatial design in the Netherlands has since the early 1990's been systematically supported by a national policy. Within this period a sophisticated infrastructure of institutions and funding incentives has created a successful and active culture of architecture, spatial design, architectural curating, architecture criticism, education, talent development, and research. Critical success factors for the Dutch policy are the separation of the cultural policy for architecture and spatial design from the art and cultural heritage sector, the 'depth' of the Dutch policy extending into fields not directly related to architecture and spatial design as well as the pro active role of the public sector assigning a central role to the architect and involving him in the beginning of the process.

The construction industry highly depends on each specialized manager which is essential to successful project. However, a new employee, who has just graduated from architectural engineering college, is requested additional education for 1~2 years such as On-the-Job-Training (O.J.T) to perform his/her professional job in construction site. It is wasteful for both construction company and the employee in terms of time and cost. The purpose of this paper is to investigate the required abilities and analyze the gap of demanded abilities between field managers and students. To collect data for analysis, questionnaire which uses Likert Scale has been performed to both parts. As a result, the analysis show that the graduate's abilities related to field experience get especially low degrees in compare with non-field experience factors. These results will contribute architectural engineering education in college to make more realized.

The performance enhancement of various structural building systems from natural hazards has become an inctreasingly important issue in engineering field. In this paper, visco-elastic(VE) CST30 damping systems were tested under cyclic loadings to evaluate their performance in terms of ductility and energy dissipation. Main test variables are relative shear stiffness, rate of loading frequency, and thickness of specimens to evaluate the seismic capacity based on the performance criteria. This experiment was performed using a total of 12 specimens, subjected to cyclic loadings up to a shear deformation of 500%. All the CST30 dampers provided a ductile and stable hysterestic behavior when subjected to the demands of large shear stiffness and different loading frequencies. The test results showed that the CST30 dampers are an effective damping systems to enhance the buildings performance for remodeling and retrofit of buildings.

The construction of a moment connection for a rectangular hollow section (RHS) column and a H-shaped beam is difficult because the RHS is a closed section. When a inner diaphragm is used for such a connection, in general, it is installed after cutting the HSS columns, which results in increased construction work. This paper suggests a new fabrication method to overcome such problems: An inner diaphragm is welded to inside a C-shaped section first, and then a column is fabricated by welding two C-shaped sections. This fabrication method is superior to a classic method in terms of constructibility. An experimental and a numerical study using Ansys 9.0 were performed in order to compare the strength of connections with respect to the presence of concrete, the corner shape of diaphragm, and the axis of loading. The experimental results including initial stiffness and ultimate loads are reported and the analytical results including load transfer mechanism, degree of stress concentration, and strain distribution are also reported.

This study presents applications of the multivariate adaptive regression splines (MARS) method for predicting the ultimate loading carrying capacity (N_u) of rectangular concrete-filled steel tubular (CFST) columns subjected to eccentric loading. A database containing 141 experimental data was collected from available literature to develop the MARS model with a total of seven variables that covered various geometrical and material properties including the width of rectangular steel tube (B), the depth of rectangular steel tube (H), the wall thickness of steel tube (t), the length of column (L), cylinder compressive strength of concrete (f'_c), yield strength of steel (f_y), and the load eccentricity (e). The proposed model is a combination of the MARS algorithm and the grid search cross-validation technique (abbreviated here as GS-MARS) in order to determine MARS' parameters. A new explicit formulation was derived from MARS for the mentioned input variables. The GS-MARS estimation accuracy was compared with four available mathematical methods presented in the current design codes, including AISC, ACI-318, AS, and Eurocode 4. The results in terms of criteria indices indicated that the MARS model was much better than the available formulae.
