%X 参数化的装配式钢混组合结构建筑信息模型缺少结构信息描述，无法实现装配式钢混组合结构图档的修正和自主更新，对结构构件的损伤评估效果差，抗震加固性能差。据此提出用于装配式钢混组合结构抗震加固的建筑信息模型，模型框架包括建筑设计模型、结构设计模型、结构抗震加固设计和损伤评估；通过结构构件的实体定义、属性定义和关联性定义，全面描述柱、梁、板和墙等钢混组合结构构件的抗震加固性能信息；采用模糊加固评估方法获取精准的结构构建综合损伤指数，评估结构构件的加固等级，提高抗震加固性能。经实验证明，所设计模型得到的结构损伤指数与实际损伤指数的误差低于0.03，说明该模型分析装配式钢混组合结构抗震加固性能准确性较高。<br>The current parameterized building information model of assembled steel-concrete composite structures lacks structural information and cannot realize the modification and self-renewal of the drawings of assembled steel-concrete composite structures. Therefore, both the damage assessment effect of structural members and the seismic reinforcement performance are poor. This paper presents a building information model for seismic reinforcement of assembled steel-concrete composite structures. The model framework included a building design model, a structural design model, a seismic reinforcement design of the building, and damage assessment. Through solid definition, attribute definition, and association definition of structural members, the seismic strengthening performance information regarding the steel-concrete composite structural members, i.e., columns, beams, slabs, and walls, was comprehensively described. The accurate comprehensive damage index of structural members was obtained to evaluate the reinforcement grade of the structural members by using a fuzzy reinforcement evaluation method. The experimental results showed that the error between the damage index obtained by the proposed model and the actual damage index was < 0.03, which indicated that the accuracy of the model for seismic reinforcement of assembled steel-reinforced composite structures is relatively high
