This study describes an application of a knowledge-based system for a part of the development of an integrated structural design system. In preliminary structural design procedure, most structural design operation are performed by structural engineer's manual method. These lack of systematic operation hampers the effective system integration. By introducing expert system to the structural planning stage, structural engineer can automate structural Planning process of an integrated structural design system for complex design. Engineering data management is receiving increasing attention due to complexity of information necessary for performing structural engineering operations. So, in this paper, we describe a methodology for automating conceptual structural design and developing a knowledge-based system integrated with database. At the end, we use an implemented example to support our methodology.

The apartment houses which were constructed in a large quantity are currently being deteriorated and the reuse of them is directly related to the economic and environmental problem of the nation. Therefore, this research approaches to structural planning other than to the materials and/or the repair for the reuse of these deteriorated buildings. The research suggests the structural planning technique which includes the idea for the reinforcement of the structure in a part to improve the structural efficiency by investigating the current condition which includes the structural type of the buildings, examining the plan for the improvement of the structural efficiency, establishing the model of the space reorganization associated to the capability changes for the scale, the use, and the facilities, and checking of the structural efficiency through the structural analysis for the building structure suggested to be replaced.

하중에 민감한 케이블을 사용하는 현수교의 기하학적 형상은 하중을 저항할뿐만 아니라 시지각적 실루엣이 된다. 이 연구에서는 정력학적 도해법이 지니는 두 가지 가능성을 이용해서 힘의 흐름을 따르는 현수교의 초기 구조형태계획법을 제시한다. 첫째, 힘다각형을 이용해서 동일한 힘에 대해서 다양한 하중경로를 모색할 수 있다. 둘째, 구조형태와 힘다각형 사이에 존재하는 상반원리를 이용해서 새로 형성된 하중경로에 대응하는 구조형태를 생성할 수 있다. 먼저 현수교의 구조적 및 미학적 측면에 영향을 미치는 주요 구조형태변수를 선정한다. 이러한 변수에 대해서 구조형태와 힘다각형의 상호관계를 분석한다. 이를 토대로 현수교의 초기 구조형태계획에 대한 일련의 설계과정절차들을 개발한다. 이 연구에서 제시하는 구조형태계획법은 유사 형태저항 구조시스템의 설계대안을 생성하는데 수월하게 확장해서 사용할 수 있다. 또한 구조형태와 힘의 흐름과의 상호관계를 설명하는 교육용 도구로도 사용될 수 있을 것으로 기대한다.

School gymnasium is a multi-purpose large space building for various events and physical education activities, and is a facility that requires an approach to the desirable structural design, besides mechanical problems of structure against loads. For the integrated structure design concerning the architectural features, the major considerations of gymnasium planning that are the internal and external shape of the gymnasium, the space scale with structure members, the structural efficiency by members weight reduction and openness of the gymnasium space will have to take into account in the structural planning. From this point of view, the several cases of the school gymnasium were investigated and the parametric analyses were performed to the models using the various structural system. The parameters were the composition elements of structure system that are profile of structure, rigidity of member, connection and anchorage and stability. At the result, It was presented that the profile of structure member was the most influential factor to structural efficiency and the effect of the form and space of gymnasium. Also the design informations of structure design having the various feature of form and space were presented for the initial gymnasium planning.

The purpose of this study is to analyze the planning characteristics of passive house by the building structural types in foreign cases. The interests and demands about passive house have been increased, and various building structural types and design methods have been attempted for passive house in Korea. But domestic research results and development experiences about passive house were lack. The results of this study are as follows; First, in terms of energy performance, insulation performance, airtightness, there are not significant differences at the 95% confidence level by the structural types of passive house. Second, in terms of the types of insulation materials, there are significant differences at the 95% confidence level by the structural types of passive house. Third, in principle there is no need of traditional heating facility in passive houses, but in practice traditional heating facilities are used additionally in about half of survey cases for the comfort of occupants.

This paper aims to explore the strategic roles of information and strategic planning capabilities for firms' performance, and to examine the direct and indirect relationships between information capability, strategic planning capability, logistics performance and competitive advantage. The present research adopts resource based theory (RBT) to explore the relationships between a firm's specific capability and its performance and employs structural equation modelling (SEM) in order to test the validation of the measurement models and examine the relationships between construct variables. The current empirical test was conducted using the data collected from logistics managers of 101 Korean electronics companies. The empirical research presents positive influential relationships between (1) information/planning formality capability and strategic planning capability; (2) strategic planning capability and logistics performance; (3) logistics performance and competitive advantage; and (4) competitive advantage and competitive position in the market.

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.

In order to establish a design guide for the bottom plate structure of a 4.3 ton aluminum planning boat, the feasibilities of bottom plate scantling of the ship are investigated based on the results of structural strength analysis and a simple equation and evaluation system are developed for initial structural design purposes. This study consists of 5 steps: First, the background, necessity, and purpose of this study are explained briefly, Second, the principal dimensions of this ship, the position of the considered bottom plate members and material characteristics are introduced. Third, the equivalent design pressure concept is introduced and evaluated based on experience and experimental data. Fourth, the strength of bottom plate members are examined using elasto-plastic nonlinear structural analysis, and response levels and several boundary conditions are reviewed based on the analysis results. Finally, in order to suggest design guides in respect to the ship's structural design, a simple design equation and evaluation system for bottom plate members are suggested for boats in the 4.3 ton aluminumboat range through the introduction of safety factorsbased on the ultimate design pressure concept.

본 연구의 목적은 건축가와 구조엔지니어가 어떻게 밀접한 관계를 유지하면서 구조계획과 구조디테일을 발전시킬 수 있는 방법론에 대하여 논하고자 한다. 실제로 일반적인 건축물이 아닌 특수 건축물에서 구조적인 거동에 관한 조사 없이 디테일 해결이란 상당히 어렵다. 그러한 조사 없이 해결된 디테일은 힘의 흐름을 정확히 예측할 수 없고 단지 조형적인 이미지만 표현될 뿐이다. 건축가와 협력관계에서 디테일 해결하는 과정을 구조 엔지니어 입장에서 제시하고자 한다.
