Housing industrialization in China is the development trend, and prefabricated concrete structure is one of the key elements. A number of pilot cities have been appointed in recent years, and design software is urgently needed. It is urgent to launch the software which is adapted to the policy guidance and market demand.PBIMS-PC software is an integrated system which contains component computational tools, structure analysis and detail design function for designers, and it transfers model data to processing equipment. The research and development of the software will simplify the design of the assembly structure, improve the work efficiency, reduce design errors, and promote the process of housing industrialization.
