摘　　要：建筑信息模型(BIM)正向设计是推动建筑业数字化转型的核心技术,是智能建造和智能运维的起点,但应用和推广仍面临阻力。总结了建筑结构BIM正向设计发展困境,指出走出困境的关键技术:面向大体量复杂建筑的高效BIM底座、面向有限元计算的拓扑关系实时维护系统、基于BIM的智能设计平台。结果表明:自研BIM底座突破了主流BIM平台性能瓶颈;拓扑关系实时维护系统实现了BIM模型和有限元模型的“双模一体”;智能设计平台建立了梁、板、柱、墙的智能配筋设计解决方案,设计了维护和管理人为干预配筋意图的机制,确保数据的一致性和可追溯性,在高效应对项目频繁修改与变更的同时,实现“图模一致”。最终,集成各项技术开发了建筑结构BIM正向设计平台,并在多个项目中应用,为智能建造、智能运维提供了完备、可靠的数字化模型。Building information modeling(BIM)forward design is pivotal technology for the digital transformation of the construction industry and serves as the foundation for intelligent construction and maintenance.However,its application and expansion still encounter significant barriers.The development challenges of BIM forward design for building structure were summarized,and the key technologies to overcome these challenges were identified:efficient BIM foundation for large and complex buildings,real-time maintenance system for topological relationships dedicated to finite element analysis,and BIM-based intelligent design platform.The results show that the developed BIM foundation surpass the performance limitations of mainstream BIM platforms,and the real-time maintenance system for topological relationships achieve integration of BIM and finite element models,facilitating“dual model unity”.The intelligent design platform implements automated rebar design solutions for beams,slabs,columns,and walls,as well as mechanisms to maintain and manage manual interventions in rebar design,ensuring data consistency and traceability.This platform effectively handles frequent modifications and changes in projects while achieving“drawing-model consistency”.Ultimately,by integrating these technologies,a BIM forward design platform for building structures was developed and applied in multiple projects,providing comprehensive and reliable digital models for intelligent construction and maintenance.
