| 1 | 简支梁桥线形变化对轻轨列车单双线运行性的影响及差异显示文摘以列车-轨道-桥梁系统动力分析理论为基础,基于商业软件ANSYS和APDL语言,针对某城市轻轨工程,建立考虑简支梁桥线形变化的轻轨列车-轨道-桥梁三维动力非线性分析有限元模型,研究桥墩沉降、梁体下挠/上拱对轻轨列车单双线运行性能的影响。研究结果表明:所建模型具有高效、稳定、可靠、可视等特点;桥梁跨中竖向位移响应在列车交会区约为单线运行时的2倍,轮重减载率与单线过桥相比无显著变化,车体最大加速度和Sperling指数较单线过桥时小幅增加;车速是影响轻轨列车运行安全性最主要的因素,其次是梁体线形变化,而运行方式影响程度最小;伴随车速增加,轻轨列车运行平稳性变差;与车体最大加速度相比,Sperling指数对单双线运行方式的影响有更好区分度。 | 王少杰 徐赵东 李舒 李红伟 Shirley J.Dyke | 2017 | 中南大学学报(自然科学版)2017，48，6： | 4 |
| 2 | Primary feather vane asymmetry should not be used to predict the flight capabilities of feathered fossils显示文摘Reconstructing flight abilities of fossil birds from preserved wings and feathers is an important goal if we are to understand the evolution of flight.Wing-shape is known to correlate well with bird flight style[1],but functional wing-shape is almost impossible to reconstruct from fossils with a high degree of certainty.In contrast,however,individual primary feathers are often | Xia Wang Robert L.Nudds Colin Palmer Gareth J.Dyke | 2017 | Science Bulletin2017，62，18： | 2 |

| 4 | Towards rapid and automated vulnerability classification of concrete buildings显示文摘With the overwhelming number of older reinforced concrete buildings that need to be assessed for seismic vulnerability in a city,local governments face the question of how to assess their building inventory.By leveraging engineering drawings that are stored in a digital format,a well-established method for classification reinforced concrete buildings with respect to seismic vulnerability,and machine learning techniques,we have developed a technique to automatically extract quantitative information from the drawings to classify vulnerability.Using this technique,stakeholders will be able to rapidly classify buildings according to their seismic vulnerability and have access to information they need to prioritize a large building inventory.The approach has the potential to have significant impact on our ability to rapidly make decisions related to retrofit and improvements in our communities.In the Los Angeles County alone it is estimated that several thousand buildings of this type exist.The Hassan index is adopted here as the method for automation due to its simple application during the classification of the vulnerable reinforced concrete buildings.This paper will present the technique used for automating information extraction to compute the Hassan index for a large building inventory. | Lissette Iturburu Jean Kwannandar Shirley J.Dyke Xiaoyu Liu Xin Zhang Julio Ramirez | 2023 | Earthquake Engineering and Engineering Vibration2023，22，2： | 0 |
