Abstract

In each industry field, many engineers have tried to develop integrated environments using information technology. The core technology in building integrated environments is the database based on standardized information. To meet the requirements, this study builds a database with detailed design information as a part of integrating digital information generated from every work of steel bridges. The data model used to build the database was developed based on the international standard, namely ISO/STEP. The data model is classified into geometric and non-geometric parts to represent the design information of steel bridges. The geometric parts are represented by a three dimensional solid model so that they may be able to reuse existing information. Also, the non-geometric parts represent information requirements that are analyzed by the development method of standard data model. To verify the data model, this study validates the syntax of the model on EXPRESS Engine and verifies the validation of the model by applying the design data of Hannam bridge to the database.

각 산업분야의 엔지니어들은 각종 정보기술을 이용하여 통합환경을 구축해 오고 있다. 통합환경 구축을 위한 핵심기술은 표준화된 정보를 기반으로 한 데이터베이스이다. 본 연구에서는 이와 같은 요구사항에 대처하고 각종업무에서 발생하는 전자정보를 통합하기 위한 일환으로 강교량의 설계정보를 포함하는 데이터베이스를 구축하였다. 데이터베이스 구축과정에서 데이터 구조로 사용된 데이터모델은 국제 표준 즉, ISO/STEP(STandard for the Exchange of Product model data)을 기반으로 강교량의 설계정보를 표현할 수 있도록 기하부분과 비기하부분으로 분류되었다. 기하부분의 정보는 기존정보의 재사용이 가능하도록 3차원 솔리드모델로 표현하고, 비기하부분의 정보는 표준 데이터모델 개발 방법론에 의거해 분석된 정보요구사항을 표현하였다. 개발된 데이터모델의 검증을 위해서, 본 연구에서는 EXPRESS Engine을 이용하여 모델의 구문을 검토하였으며, 한남대교의 설계 데이터를 데이터베이스에 저장하여 개발된 모델의 타당성을 입증하였다
