内容提要 本书涵盖了车桥耦合作用相关的理论基础知识和工程应用。车辆行驶通过公路桥梁时会引发桥梁振动，桥梁也会反过来影响车辆的振动，这种车桥耦合作用带来了许多有用的信息。一方面，虽然传统上通常将车辆视为桥梁的载荷，但它们也可以被视为桥梁结构响应的传感器和接收器。另一方面，虽然传统上桥梁通常被视为车辆重量的承载结构，但它们也可以被视为可以衡量车辆载荷的秤。基于这些观察和发现，作者的研究小组开展了在车桥耦合振动领域的广泛研究。本书将记录新的理论发展和应用，为相关研究人员和研究生们提供参考信息。 本书适合桥梁工程领域的研究生、专业人士和研究人员阅读。读者应在已经完成了结构动力学、桥梁工程等相关课程的基础上阅读本书。 目录 Chapter 1 Introduction1．1 Background and Thematic Basis1．2 Promising Approach to Dealing with Highway Infrastructure Problem1．3 Book OrganizationChapter 2 Framework of Vehicle-Bridge Coupled Modeling2．1 Introduction2．2 Methodology2．2．1 Modeling of Vehicle2．2．2 Modeling of Bridge2．2．3 Road Surface Condition2．2．4 Assembling of Bridge-Vehicle Equatioof Motion2．3 Numerical DemonstratioExample2．3．1 Impact Factor and Dynamic Load Coefficient2．3．2 Effect of Road Roughness2．3．3 Effect of Vehicle Damping2．3．4 Effect of Vehicle Rigidity2．3．5 Effect of Vehicle Weight2．3．6 Effect of Vehicle Speed2．3．7 Results iFrequency Domain2．4 ConclusionsReferencesChapter 3 Vehicle-Induced Impact oBridges3．1 Definitioof Impact Factor3．2 Bridge Code Provisions Worldwide3．2．1 AASHTO Code3．2．2 Ontario‘s Code and CanadiaCode3．2．3 Chinese Code3．2．4 ZelaniaCode3．2．5 AustraliaCode3．2．6 EuropeaCode3．2．7 British Code3．2．8 Japanese Code3．3 Numerical Simulatioof Effect of Approach SpaCondition3．3．1 Mechanism and Modeling of Bump and Road Roughness．3．3．2 Selected Vehicle and Bridge Models3．4 Dynamic Responses of Slab Bridges under Different Conditions3．4．1 Effect of Vehicle Speed3．4．2 Effect of Approach SpaCondition3．4．3 Effect of Bridge Deck Surface Condition3．4．4 IMs of Slab Bridges3．5 Dynamic Responses of Slab-on-Girder Bridges under Different Conditions3．5．1 Effect of Approach SpaConditioothe Mid-SpaDefiection3．5．2 Effect of Approach SpaConditioothe Dynamic Tire Force3．5．3 IMs of Slab-on-Girder Bridges3．5．4 Concluding Remarks3．6 Local and Global Impact Factors of Bridges3．6．1 Problem Statement3．6．2 Dynamic Responses of Bridges3．6．3 Effect of Bridge SpaLength3．6．4 Effect of Road Surface Condition3．6．5 Effect of Vehicle Speed3．6．6 DiscussiooCode Provisions3．7 Influence of Damaged ExpansioJoint oImpact Factors3．7．1 Effect of Bridge SpaLength3．7．2 Effect of Road Surface Condition3．7．3 Effect of Vehicle Speed3．7．4 Concluding Remarks……Chapter 4 Vibration-Based Damage Detectioand Characterizatioof BridgesChapter 5 Assessment of Vehicle-Induced Fatigue of BridgesChapter 6 Vehicle-Induced Vibrations of High-Pier BridgesChapter 7 Vehicle CharacterizatioBased oVehicle-Bridge InteractionChapter 8 Energy Harvesting oVehicle-Induced Vibrations of Bridges 作者介绍
