Abstract: The BIM component is an important BIM resource in BIM application process of construction enterprises, which reflects the maturity and competitiveness of BIM application of an enterprise. The systematicness and completeness of BIM component library play a very important role in the creation and application of BIM model in construction enterprises and the efficiency of BIM modeling. Currently, construction companies are always lacking of standardized BIM component management, facing with many difficulties of low standardization of BIM components, high cost of software and hardware, lack of support of BIM component management platform, and etc. By standardizing the management methods and processes of BIM components, the study in this paper analyses the functional and performance requirements of BIM component library system, completes the main function design of BIM component library management system, and establishes BIM component library management system of construction enterprise based on public cloud, which provides a feasible technical route for enterprise BIM component library management.

Abstract:
It is common at present in sutructrual designing area that the models built in the computing softwares are transmitted into the BIM softwares, which reduces the BIM structural designing efficiency compared with adopting AutoCAD. It is necessary for structural design and plug-in development to create a structural model in BIM software and then to transmit into computing software. This paper takes the transmission of a model of frame and bent structure from Revit to STAAD.Pro as an example, to study some noticeable issues in Revit modeling and writing Revit data into*.std file, based on which we propose corresponding processing method and the improvemnt suggestions for Revit, STAAD.Pro & SSDD.
