基于BIM技术与模拟退火算法的村镇轻钢框架结构智能设计方法
Intelligent design of rural light steel frame structure based on BIM and simulated annealing algorithm
摘要
Abstract
In the traditional structural design process,rural buildings require a lot of manual calculations and repeated modeling.However,due to the constraint of construction cost,they cannot be designed and checked professionally as urban types,and the safety and economy are difficult to meet the requirements.In this study,an intelligent design approach for structural design of rural light steel frame structure was proposed,including the intelligent modeling and optimization.Based on the automatic layer classification method(ALCM),optical character recognition technology(OCR)and adaptive block algorithm,BIM intelligent modeling method was proposed where layer recognition,the extraction of axis text data and wall contour were included,and generated structural models satisfied the requirements of engineering practice.Based on the proposed two-stage simulated annealing algorithm,the intelligent optimization method was proposed and verified by case histories.Results showed that the proposed intelligent design method was feasible.Compared with the traditional method,its time use could be shortened by more than 70％,and the material consumption and structural design parameters were similar.关键词
