摘　　要：确立物化阶段碳排放计算模型,完成基于定额的综合碳排放因子库的建立.以装配式剪力墙结构物化阶段碳排放量最低为目标函数,梁的截面尺寸、墙的厚度、墙的长度、墙混凝土强度为变量,考虑构件强度、建筑条件、位移约束,利用优化软件Lingo建立优化模型并求解构件最优尺寸及混凝土强度.以实际案例验证了该优化方法的可行性,为进一步推动装配式建筑在设计阶段的发展提供了参考.A calculation model for carbon emissions from the physicochemical stage was built to establish an integrated carbon emission factor bank based on quotas.The objective function is the lowest carbon emission from the physicochemical stage of the fabricated shear wall structure,and the variables are the section size of the beam,wall thickness,wall length,and strength of the concrete wall.Considering the strength,building condition,and displacement constraint of the member,an optimization model is established using the optimization software Lingo,and the optimal size of the member and the strength of the concrete are determined.The feasibility of the optimization method is verified using a practical case study,which provides a reference for further promoting the development of prefabricated buildings in the design stage.
