摘　　要：商业建筑结构内人行连桥的舒适度对商场体验影响重大,现阶段建筑结构对楼盖舒适度的分析,主要采用时程分析法和有限元法。通过对常州某大型商业内的大跨混凝土连桥研究,从施工工况到设计荷载使用工况下各个阶段的舒适度分析和初步实地验证,得出商业大跨连桥舒适性影响关键因素,进而提供普通商业混凝土大跨连桥舒适度的设计管理思路。The comfort of pedestrian bridges within commercial building structures has a significant impact on the shopping experience.Currently,floor comfort analysis in building structures primarily utilizes time history analysis method and finite element method.Through the study of a long-span concrete pedestrian bridge within a major commercial complex in Changzhou,from the construction conditions to the design load use conditions,the comfort analysis at various stages and preliminary on-site validation are conducted,identifying the key factors affecting the comfort of commercial long-span pedestrian bridges.Furthermore,it provides a design management approach for the comfort level of ordinary commercial concrete long-span bridges.
