1带水平滑移层的空心砖填充框架抗震性能试验显示文摘为了降低地震作用下填充墙体的破坏程度,提高填充墙体的变形可恢复性能,基于框架填充墙破坏模式,提出了在空心砖填充墙中设置水平滑移层的构造措施;设计并制作了两组足尺填充墙框架构件,进行了拟静力试验,研究了带水平滑移层的填充墙框架的抗震性能;提出了衡量填充墙破坏程度的计算方法,比较了增设水平滑移层的构造措施后填充墙体的破坏程度.分析结果表明:空心砖填充墙增设水平滑移层后,填充墙体的斜撑作用弱化,水平滑移层的设置改变了墙体的破坏模式,墙体破坏由对角破坏转向滑移破坏,框架构件的耗能能力增加,填充墙体的破坏程度和构件的残余变形显著降低,残余变形下降了27%,填充墙体破坏率最少降低93%以上.苏启旺 李义 卜庆涛 程权林 HANI Meree 2022西南交通大学学报2022,57,1:2
2New Insights into Intravascular Imaging of Coronary Bifurcation Lesions and Left Main Stenosis:What Have We Accomplished?显示文摘Coronary bifurcation lesions(CBL)are one of the most challenging lesions to treat in interventional cardiology.Intravascular imaging including intravascular ultrasound(IVUS)and optical coherence tomography(OCT)is paramount for the assessment of lesion characteristics and suboptimal stent results and to improve the outcome of percutaneous coronary intervention(PCI).After upgrading the use of IVUS and OCT by the American College of Cardiology/American Heart Association guidelines,their use has increased.Likewise,there has been significant improvement in image quality and the profile of system(ie,IVUS catheter size).The main indication for the use of IVUS includes:assessment of lesion characteristics,optimization of stent deployment,optimal stent expansion,exclusion of plaque burden>50%,and edge dissection.Intravascular imaging plays a significant role in the assessment and treatment of left main(LM)coronary artery stenosis and CBL.In particular,the use of intravascular imaging for alleviating mechanical issues during stenting and managing stent thrombosis has significantly increased.Overall,a compelling body of evidence has shown that the use of IVUS or OCT during PCI leads to optimal stenting results and mitigates the risk of adverse cardiac events.However,to date,the American College of Cardiology/American Heart Association Guidelines have assigned a Class IIb recommendation for IVUS or OCT,while the European Society of Cardiology Guidelines upgraded it to the Class IIa recommendation.This review summarized the role of IVUS and OCT for the assessment of stenosis and stent optimization in patients with CBL and LM stenosis.In addition,we discuss new insights into the role of IVUS-and OCT-guided stenting in patients with CBL and LM stenosis provided by the ongoing randomized trials.Massoud A.Leesar Gregory O.Von Mering Hani Jneid 2022Cardiology Discovery2022,2,3:2
3Behavior of traditional concrete dams and three-dimensional printed concrete dams under the debris flow impact显示文摘This study investigated the resilience of traditional concrete dams compared to 3D printed concrete dams(3DPC)when subjected to debris flow.Three types of dams,namely check dams,arch dams,and curve dams,were numerically analyzed using a three-dimensional Coupled Eulerian-Lagrangian(CEL)methodology.The research focused on critical factors such as impact force and viscous energy dissipation to compare dam performance.Additionally,the study examined the printing and service phases of 3DPC models,determining potential failure modes and analyzing printing parameters.The results demonstrated that 3DPC dams outperformed traditional concrete dams,with filament deposition orientation,perpendicular to the debris flow direction,identified as a pivotal factor.Infill percentage and pattern were also found to influence the behavior of 3DPC models.Notably,curved dams exhibited superior performance based on dam geometry.These findings have significant potential for advancing the development of resilient dam structures capable of withstanding debris flow impacts.MEREE Hani YAN Shuai-xing WANG Dong-po BI Yu-zhang 2023Journal of Mountain Science2023,20,12:0
