For the lower degree of modularization of maritime terminals structure design,we apply BIM modeling technique to carry out the structural design based on two maritime terminals being built,including component building,parameters assignment and structural reinforcement.Structure and function check can be practiced in the model.Modulized structure design is achieved with improvement of quality and efficiency.Output includes drawings and construction scheme,and both real project and digital project are handed in.The results show that using BIM technique as modulized design methodology can evidently facilitate the design process and achievements sharing.However,no uniform standard is available for the time being,resource sharing is still hard to realize in the industry.
