摘要
为减少建筑碳排放量,装配式混凝土框架结构的构件设计需要通过分析参数变化对碳排放的影响来确定最优方案。应用正交设计法确定试验构件数量,并通过BIM建模和工程量统计,分析预制率、混凝土强度、配筋率、梁板柱尺寸等对构件碳排放量的影响;采用层次分析法(Analytic hierarchy process, AHP)方法确定了参数权重,并给出了工程设计优化建议。结果表明:根据各设计参数的敏感性比较结果,参数影响性排序为混凝土强度、板厚、柱高、预制率、配筋率、尺寸。该研究可为双碳时代背景下装配式混凝土框架结构设计提供工程决策参考。
In order to reduce the carbon footprint of buildings,the optimal solution to the component design of prefabricated concrete frame structures needs to be determined by analyzing the effects of parameter variations.The orthogonal design method was applied to determine the number of test elements,and the influence of prefabrication rate,concrete strength,reinforcement rate and beam-slab-column dimensions on the carbon emissions of the elements was analyzed through BIM modelling and volume statistics;the analytic hierarchy process(AHP)was used to determine the parameter weights and give suggestions for engineering design optimization.The results show that,based on the results of the sensitivity comparison of various design parameters,the parameters are ranked in order of influence as concrete strength,slab thickness,column height,prefabrication rate,reinforcement rate and dimensions.The study can provide reference for engineering decisions on the design of assembled concrete frame structures in the context of the dual carbon era.
