研究领域
智能无线传感器技术损伤识别和健康监测结构控制随机疲劳随机计算力学地震工程信息技术在土木工程中的应用
科研项目
1. 建筑结构的主动基础隔震技术
该项研究的目的是再震动系统中应用被动和主动控制技术。为了研究该技术,在伊利诺伊州立大学香槟分校的智能结构技术试验室建成了一个三层两跨的剪切型结构,该结构放置在一个基础隔震层上并使用3个作动器完成被动和主动控制的平面内试验加载。研究和开发一种既能保持合理的基底位移又能降低结构加速度和剪力响应的控制方法。当前的工作主要集中在结构识别和作动器平面内加载控制方面,控制程序将仅仅用在3个作动器的楼层加速度和位移的反馈控制中。在前期工作的基础上,后期还将把研究扩展到3维结构的控制领域。
2. 实时混合试验技术
混合试验是将试验室试验和数值分析有效的结合成了一个系统。当速度依赖现象显著的时候,实时进行混合试验就显得非常必要。在实时混合试验中,试验系统的动力特性会变得非常重要。本项目主要研究通过一些方法的改进试验系统的动力特性。并通过MR阻尼器完成验证性试验。
3. 斜拉桥的地震响应
斜拉桥近年来得到了广泛应用,但在之前的一些地震中很多斜拉桥都受到了灾难性的破坏。其破坏机理包括:桥墩破坏,桥板跌落和节点破坏。AASHTO设计规范规定斜拉桥应进行非常规结构的分析和非线性三维时程计算。振动模态的复杂耦合和钢筋混凝土桥墩的效应都必须要在当前的设计规范中得到体现,以避免将来的桥梁再在地震中发生坍塌事故。为了更好的研究这一复杂的现象,1/20比例尺的斜拉桥振动台试验和有限元分析都在进行中。
4. 用于地震影响评估的混合仿真综合系统的开发
该项目旨在开发一个可以将现场的NEES模式混合仿真、结构传感器测量数据、基于模型更新技术的系统识别、概率性的脆性分析和地震影响评估整合在一起的系统,并为该系统建立一个试点(Cape Girardeau大桥)。将会研究出新的算法,并将连接传感器的测量数据通过传输协议直接与NEES系统相连。现场测量将被用于描述现场风险的特征并定义强震记录,结构传感器用于建立桥-基础-土体模型。通过改变1-3个桥墩的设计,使用建立的数值模型和地震动记录进行混合仿真。根据地震动记录的不同,桥梁的响应也会不同,桥墩的响应将会被用于推导脆性关系,在风险水平附近,该关系将被用来估计地震的影响。
5.传感器/结构健康监测
该项目主要研究智能传感器网络在结构评估和损伤识别中的应用,主要进行一下几个子课题的研究:
(1)损伤识别算法的研究
(2)智能传感器网络的开发和实施
(3)足尺桥梁的健康监测
