IFC를 이용한 건축강구조 표준접합상세의 표현

BIM is one of the most promising developments in the AEC industries and some building projects are in progress with BIM. For progressing the projects with BIM, data exchange is most important and IFC is the core technology for it. But, IFC is not used widely in structural engineering for standard steel connections. This results from the lack of understanding on IFC data model, and deficiency of properties for representation of standard steel connections. The purpose of this paper is to store and manage the data using IFC, and propose the new property sets for standard steel connections. For this, we investigated the method and data model of IFC to represent the standard steel connections, such as column-beam connection, beam splice, column splice, and girder-beam connection. Based on these investigation, we proposed the new property sets for utilization of the IFC data model on standard steel connections. Then, we generated sample IFC files in which the data on standard steel connections according to the proposed new property sets. Finally, we developed the application program to verify the reasonability of the proposed new property sets. As a results, we concluded that the data on standard steel connections can be stored and managed sufficiently by using the IFC data model and proposed new property sets.
