Every year new tall buildings are being conceived, designed, and built with new schemes. Thus it is important to explore the factors that affect tall building design. Thus it is important to explore the tall building design factors. The planning and design of tall buildings require different criteria than those that exist in regular size buildings. Tall buildings are uniquely expressed by their structural systems where exterior esthetic and requirements of space drive the form and composition of the structural systems. Therefore the exploration of design factors is the key to achieve optimum building systems. Optimization as mentioned here is associated with the efficiency of the different building systems. To achieve an optimal system, there is a need for an understanding of the factors that affect on overall tall building design such as planning module, building function, lease span, floor-to-floor-height, building height (aspect ratio), structural system, environmental systems. In this paper a statistical approach will be used and will be based on data collected from the practice through a rigorous survey taken. This information is tabulated and analyzed. The major target of investigation will be lease span related to space requirement in the tall building planning. Factors related to lease spans, such as function, floor-to-floor height, planning module, building height, overall plan dimension, and plan ratio (building geometry), will be looked at carefully. IN conclusion, this approach of optimization can introduce a preliminary design guideline for tall building projects. The purpose of the paper should shed some light on the optimum tall building design criteria.

Local responses of steel plate-concrete composite (SC) walls under impact loads are typically evaluated using design equations available in the AISC N690s1-15. These equations enable design of impact-resistant SC walls, but some essential parts such as the effects of wall size and shear reinforcement ratio have not been addressed. Also, since they were developed for design basis events, improved equations are required for accurate prediction of the impact behaviors of SC walls for beyond design basis impact evaluation. This paper presents a numerical study to construct a robust numerical model of SC walls subjected to impact loads to reasonably predict the SC-wall impact behavior, to evaluate the findings observed from the impact tests including the effects of the key design parameters, and to assess the actual responses of full-scale SC walls. The numerical calculations are validated using intermediate-scale impact tests performed previously. The influences of the fracture energy of concrete and the conservative aspects of the current design equations are discussed carefully. Recommendations are made for design practice.

The purpose of this paper is to study the meaning of Rem Koolhaas's works focused on Villa Dall'Ava. This House which offers a fine example of the early architectural concepts of Rem Koolhaas was completed in 1991, 7 year earlier than the Maison Bordeaux and also this work is the only one house constructed in Paris. Rem Koolhaas, one of the most influential architects representing contemporary architecture in these days is interpreted so diversely as new constructivism, deconstruction and new scientism etc. The relationship between Modernism architecture and the architecture of Rem Koolhaas is supposed in various point of view in recent studies. Although the leading background on which the architectural inclination of Rem Koolhaas is de-constructivism, various interviews, editorials and other perspectives give clue that Rem Koolhaas was influenced by Modernism. His architectural concept is connected with the architectural principles of Le Corbusier: 'Five Points of a New Architecture' and 'Dom-ino system', which are especially applied a lot to Villa Dall'Ava in the modified form. This study is to research the architectural characteristics of Villa Dall'Ava by analyzing the layout, plan, elevation, section and structure, which revealed the architectural connectivity between the concept of Rem Koolhaas and the architectural principles of Le Corbusier which had a great effects on architectural history and became a fundamental elements for the change into the modern architecture. In practice, the architectural work of Rem Koolhaas remind the architectural principles of Le Corbusier. This research appraises each points of 'Five Points of a New Architecture' in regarding with Villa Dall'Ava whose study will be important to find the meaning of the works and ideas of Rem Koolhaas.

The original members of the De Stijl group, formed in neutral Holland during the First World War, included the painters Piet Mondrian, Bart van Leck and Theo van Doesburg, and the architects J.J.P. Oud and Jan Wils. The aim of the group was to create a language of form and color applicable to every sphere of modern life. The means of expression selected by the De Stijl artists was rigorously restricted, using only vertical and horizontal lines with the right-angle created where they cross, and for color, black, white and the primaries- red, yellow and blue. Of these simple elements consisted the compositions painted by Mondrian and van Doesburg during the years around the end of the First World War, and the famous red-blue chair made by Gerrit Rietvelt in 1917. They did share a common influence, Cubism, and they both emphasized contemporaneity. Otherwise they were quite different movements, both in theory and practice, except lot one further point of similarity.

As a result of imminent recognition on nature from modern world, the need for the combination between architecture and nature has been raised as another topic in architectural arena, and this kind of work is being conducted under the notion of Landscape. As the term 'Landscape' emerges as the key word in contemporary architecture, 'Landscape' begins to transcend the mere meaning of landscape architecture(gardening). The word, Landscape, has gone beyond the meaning of mere landscape, or rural vista one-dimensionally, and, after having introduced the attributes of nature into building activities, has emerged as a notion trying to form 'the architecture as landscape.' Together with these, 'Landscape' is expanding as a notion having various layers. The notion's, 'Landscape', occupying the significant position in contemporary architecture has been a recent phenomenon over 1980-1990s, and its category of practice has not certain limitation, rather it has started simultaneously from various areas. This study, before reviewing the architectural notion of Landscape by studying the Landscape notion and its various embodying methods being shown in contemporary architecture. As a result of examining the features of Landscape notion shown in various directions(ways), being influenced by the four Landscape types presented by Eduard Bru and the currents of the times, we can see that, though the features are somewhat similar, they are classified and explained as different types respectively. So, we are able to recategorize the features into 6 domains in this study.

Traditional architectural space, which is a historical cultural heritage must be connected mutually as a organic flow of various elements such as the environment of the time, political background and values, rather than approaching with fragmentary point of view. The Silhak Philosophy, the basis of late Chosun society developed equity thoughts on the basis of ideology of humanism, and it asserted the promotion of technology and industry as a measure to realize the pursuit of truth which is practically useful. Thus, we could verify the possibility of convergent interpretation of cultural technology of Hwaseong architectural space through the humanistic viewpoint of pioneer spirit of Silhak Philosophy which regards human as a main agent of desire of life, and the pursuit of truth which is useful for reality, and the realization of ethical value by aesthetic practicalism. Based on this, the ontological meaning and value of Suwon Hwaseong by the viewpoint of convergence of culture and technology have been drawn as the construction of planned new town by the practice of filial duty, the plan of city space based on rational values, the realization of a metropolis where self-sufficient economic activities are possible, the introduction of thorough construction management system, the introduction of advanced culture and its creative application, and the application of scientifical knowledges and cutting-edge technology.

In recent years, schools in the urban areas are also showing their interest in the integrated school and considering adapting the actual operation method. That is why decline of the school-age population is not limited to rural areas any more, and decreasing number of students in urban schools is raised as a social issue to reconsider the continuation of schools. To solve the problems of the small-scale schools in the urban area, the integrated school is being considered as an alternative. Furthermore, the newly built schools in the urban development areas are also planned as the integrated school. Accordingly, the purpose of this study is to examine the cases of integrated schools in urban area of developed countries and to analyze their architectural planning considerations in practice.

This study intended to introduce the method of designing an eco-friendly building based on BIM(Building Information Modeling) and BIM-based application. The proposed application aimed to generate the environmental performance of the designed alternative automatically in real-time manner in the process of architectural design. We focused on the feasibility of BIM-based eco-friendly design process and the applicability of the developed application for the architectural design practice. In this manner, in the end of paper, we proposed the so-call EcoBIM which is the performance evaluation module for the designed alternative using BIM in the real-time manner and the new design process with it. EcoBIM generate the coefficient of overall heat transmission of wall, roof and slab of the designed alternative with their physical characteristics such as thickness, thermal resistance and so on.

Architects are facing increasing risks that result from heightened expectations of benefits and performance when designing green buildings compared to traditional buildings. This study aims to explore the possible risk factors for architects in green building projects in South Korea and assess risk mitigation measures. To attain this goal, 14 risk factors and 12 mitigation measures were determined through an extensive literature review. A questionnaire was administered to architects practicing green building design and criticality index was employed to assess major risk factors and mitigation measures. This study identified 'adoption of new technology and process', 'green building certification results', 'building products and materials', and 'energy saving uncertainty' as the major risk factors of green building projects. Additionally, the questionnaire proposed 'contract indicating each party's role, liability, and limitations clearly', 'utilizing integrated design process', and 'understanding client's goal in green building projects' as the three most effective risk mitigation measures in designing green buildings. There are few studies that focus on architects' perceived risks concerning green building projects; this study contributes to a deeper knowledge and attempts to fill the current literature gap, which would benefit South Korea's green building design practice by aiding in the development of better risk management strategies.
