摘要:成本控制对建筑工程至关重要,建筑结构优化设计是控制工程成本的关键一步。传统的结构优化往往侧重于结构可靠度,围绕安全性、适用性、耐久性进行优化,优化目标单一,难以计及结构优化与全专业及建造阶段的协同。BIM技术全专业协同设计拥有可视化、参数化、可协调性等优点,设计过程中能减少误差,提高设计效率,实现标准化设计。本文结合BIM相关软件平台等,对某工程实例建立包含建筑、结构专业的信息模型,在保证结构可靠度的前提下,综合考虑项目钢筋用量、现浇混凝土体积、模板面积、人工消耗等因素影响,提出优化后的结构方案,并对不同结构方案的项目工程造价进行直接分析,给出了基于BIM的结构优化流程。结果表明,通过BIM技术进行优化设计,结构布置方案更加合理,工程造价有效降低,BIM技术与结构优化设计结合简化了优化设计流程,提高了优化效率,有助于项目各参与方直观地控制工程成本。
Abstract: The engineering cost control is crucial in the construction industry, and structural optimization is a key step for the project cost control.Traditional structural optimization always pays too much attention on structural reliability, including the safety, applicability and durability of the structure, whose target is too single and focused, which could hardly consider the overall collaboration of structural optimization with other professionals or during the construction stage.The BIM technology possesses the advantages of visualization, parameterization and coordination, which is able to reduce errors, improve efficiency and achieve standardized design.By using BIM-related platform, this paper firstly establishes an architectural and structural model for a project case study.In the premise of ensuring structural reliability, the influences of factors including reinforcement amount, cast-in-place concrete template volume, formwork area, artificial consumption, and etc.of the project are overall considered to put forward the final structure scheme.Different project construction costs of all these structural schemes are also analyzed to propose a BIM-based structure optimization process.The result shows that by utilizing BIM technology, structural optimization is more effective with more reasonable layout scheme, lower project construction cost, and a more simplified optimization design process, which helps the project participants to control the cost of the project more directly.
