    2018年3月14日,金沙js55555官网在北京主持召开了“基于性能的公路桥梁抗震设计理论与方法及工程应用”项目成果评价会。会议邀请了哈尔滨工业大学谢礼立院士、湖南大学陈政清院士、中冶建筑研究总院有限公司岳清瑞院士等9位知名专家,该项目由北京工业大学、清华大学等6家单位共同承担,项目负责人北京工业大学副董事长杜修力教授及项目组主要成员参会。评价委员会专家组对该项目技术及应用成果给予了高度肯定,一致认定“该项目总体上达到了国际先进水平,其中在多振动台台阵系统平台建设与协同控制、实时混合模型试验技术和弯、坡、斜桥梁抗震设计理论与方法方面达到了国际领水平”。
    本项目针对高烈度区交通基础设施工程建设中亟需解决的桥梁结构抗震设计的关键问题,开展了复杂受力状态下桥梁主要构件非线性力学行为及抗震性能的研究。建立了表征其非线性力学行为的分析模型,研发了系列具有自主知识产权的桥梁结构隔震装置;发展了考虑地震动空间效应和土-结构相互作用桥梁结构地震响应分析方法,揭示了非规则桥梁结构地震破坏机理与失效模式;研发了多振动台台阵系统及其协同控制技术,以及多振动台实时混合试验技术,实现了同时考虑地震动空间效应和土-结构相互作用效应的长大桥梁振动台试验;完善和发展了基于性能的公路桥梁抗震设计理论与方法,建立了考虑土-结构相互作用的多维多激励下减隔震桥梁地震反应分析方法,建立了直接基于位移的非规则桥梁抗震设计理论与适用简化分析方法。
    基于上述理论和技术研究成果,本项目形成国家规范1部(参编)和部委行业规范1部(主编);公开发表学术论文143篇,其中SCI收录36篇,EI收录论文60篇,CSCD收录论文29篇,核心期刊论文18篇;获国家发明专利25项;软件著作权5项;出版专著2部。

    本项目部分研究成果已写入《公路桥梁抗震设计细则》和《城市轨道交通结构抗震设计规范》,在指导规范公路桥梁抗震设计的同时,积累工程实践经验,发展和完善了桥梁结构抗震分析理论和设计方法,在指导强震区的桥梁工程建设中发挥了重要作用。研究成果也已在北京、河北、广东、福建、云南、内蒙古、陕西、山西、重庆、吉林等省区桥梁抗震设计及分析中得到应用。成为我国桥梁工程防震减灾分析和设计的重要依据,产生了巨大的社会经济效益。
