Abstract: Reinforced concrete(RC)is a component of a concrete-based frame structure.It accounts for a large proportion of the cost.Traditional steel bars picking has such problems as deviation calculating the amount of material, picking no effective rules and so on, which lead to unnecessary increase of steel bars cost.Building information modeling(BIM)virtual simulation technology can guide the actual engineering.This study focuses on two major aspects: (1)detail construction design and(2)steel bars picking to combine BIM technology and optimization algorithms to establish a preliminary procedure of BIM-based Revit reinforcement and steel bars picking methodology.This study provides ideas for later development of BIM-based steel bars picking plug-in software to achieve steel bars picking optimization and reduce waste of resources.
