This study presents an application of object-oriented methodology for structural dcsign process. A prototype system of integrated a structural design system is developed by introducing a structural analysis object model(SAOM) and structural design object model(SDOM). The SAOM module. which is modeled as a part of structural member, performs structural analysis using FEM approach and the SDOM module checks structural members based on Korea steel design standard.

The development of computer-integrated design systems that fully support structural design process needs the computerization of structural design at the preliminary design stage. The objective of this paper is to develop a prototype system for preliminary design of reinforced concrete structures. This study focuses on the development of a natural design process oriented GUI(Graphic User Interface) and a representation of an experienced knowledge. The prototype system has been currently implemented using the objected-oriented programming concepts, the program language(i.e.,Visual C++) and the expert shell(i.e., Intelligent Rules Element).

A smart connective control system was invented recently for coupling control of adjacent buildings. Previous studies on this topic focused on development of control algorithm for the smart connective control system and design method of control device. Usually, a smart control devices are applied to building structures after structural design. However, because structural characteristics of building structure with control devices changes, a iterative design is required for optimal design. To defeat this problem, an integrated optimal design method for a smart connective control system and connected buildings was proposed. For this purpose, an artificial seismic load was generated for control performance evaluation of the smart coupling control system. 20-story and 12-story adjacent buildings were used as example structures and an MR (magnetorheological) damper was used as a smart control device to connect adjacent two buildings. NSGA-II was used for multi-objective integrated optimization of structure-smart control device. Numerical simulation results show the integrated optimal design method proposed in this study can provide various optimal designs for smart connective control system and connected buildings presenting good control performance.

초고층건물의 구조설계 정보에는 설계작업 프로세스 모델, 설계정보 전산모델, 기본설계 프로그램 및 설계 도서생성 프로그램 개발 등 여러 가지 특성화된 부분으로 구성되어 있다. 기존의 구조 설계정보는 통합적으로 관리되는 기능이 없기 때문에 건설 정보 교환에 대한 공유가 제대로 이루어지지 않고 있다. 이러한 설계정보의 데이터 수정 및 공유를 합리적으로 처리하기 위해서 통합설계에 대한 필요성이 증가하고 있다. 또한, 초고층 구조설계에서는 건설정보의 표준화가 이루어진 후 합리적인 정보교환을 위해서도 통합설계의 필요성이 대두되고 있다. 본 연구에서는 초고층건물의 구조설계를 위하여 STEP을 이용한 초고층 구조설계의 개념을 소개하고 초고층건물의 구조설계방법에 대한 질량 엔티티 및 기둥축소량 엔티티, 사용성평가 엔티티를 제안하고자 한다.

구조물의 지진응답을 저감시키기 위하여 추가적인 감쇠기나 진동제어장치가 일반적으로 사용된다. 이때, 추가적인 감쇠장치의 제어성능은 대상구조물 특성의 변화 없이 검토된다. 본 연구에서는 구조물과 스마트 제어장치의 다목적 통합최적화를 수행하였고 스마트 최상층 면진시스템이 설치된 구조물의 구조물량 저감의 가능성을 분석하였다. 이를 위하여 20층 예제구조물이 사용되었으며 MR 감쇠기와 저감쇠 탄성베어링을 사용하여 스마트 면진시스템을 구성하였다. 중약진지역의 설계스펙트럼을 바탕으로 생성된 인공지진하중을 사용하여 구조해석을 수행하였다. 수치해석결과, 스마트 최상층 면진시스템이 중약진지역에 있는 구조물의 응답과 면진층 변위를 동시에 효과적으로 줄일 수 있는 것을 확인하였다. 본 연구에서 제안된 통합최적설계기법으로 구조물량 및 감쇠기 용량을 적절하게 줄이면서도 우수한 제어성능을 발휘하는 다양한 설계 대안을 제공할 수 있었다.

This study is concerned about the design and structural analysis of high integrated tool tower ATC(Automatic Tool Changer) for machine tool. Recently, many studies have been undergoing to reduce a working time in a field of machine tool. Tool tower ATC belongs to reduce a stand-by time by shortening a tool exchanging time. The developed system can store more number of tool in small space than other machine. The analysis is carried out by CATIA V5 software. In the result of structural analysis, the safety factor of the developed system is confirmed.

The development of Reinforced Concrete member design modules is necessary for user to design structures easily. The purpose of this paper is to be available for a integrated system used structure design. This module is linked with central database for the benefit of minimizing time of design and user's efforts. In order to minimize memory space, all of data is stored in central database. Member design modules applied Object-Oriented concepts are possible to be reusible, flexible for member functions in classes. This modules can be operated both independent member design modules and a part of integrated system. Sooner or later, this modules will be related to member grouping modules by data.

An entity-based integrated design model can be used to organize and represent information and activities involved in design. The model involves a number of product and process entities. Product entities describe design information, and process entities describe design activities. The relationships among entities Includes organizational, interaction, and sequence relationships. The paper focuses interaction relationships among design information. The interaction relationships can be represented as constraints. Types of constraints includes demand constraints, dependency constraints, and interaction constraints. The paper describes dependency and Interaction constraints. The concepts of representing and processing dependency and interaction constraints in an entity-based integrated design model are presented.

In this paper, we propose the integrated design method that enables multi-physics modeling and coupled-field analysis by connecting an electromagnetic field and a structural field. We design the 3-axis moving magnet type actuator that has the high structural stiffness and the effective electromagnetic circuit generating large electromagnetic force. Through design of experiments (DOE) and optimization, the designed actuator is optimized and satisfies high dynamic characteristics over the desired specifications.
