Research on Precast Concrete Structures with BIM Involving Information on Structural Details and Behaviors

摘要

Building Information Model (BIM) is considered as a promising means to facilitate the application of precast concrete (PC). Ordinary BIMs involve the information on geometry, materials, manufacturing details, quantities and so on, which are determined after designing. However, the component details and mechanical behaviors of PC structures, which are usually ignored in the BIM during designing, could profoundly affect the final structural forms. In this paper, several different precast beam-to-column connections applied in China were modeled as the basic components with BIM software, and similar precast moment-resisting frame models were designed with these connections meeting requirements of building codes. Finally they were compared in terms of quantity and total cost. Conclusions came that it was important to build the structural system library of PC including the information of component details and mechanical behaviors in BIM.
