Abstract ：
为实现剪力墙结构震损后的快速修复,提出一种水平缝钢制连接的可修复装配式剪力墙结构(Repairable precast shear wall with horizontal steel connections,RPW-HSC),采用 ABAQUS 软件对高宽比为 1.0 的 RPW-HSC试件进行建模分析,数值模拟结果与试验结果吻合良好.通过有限元参数化建模,研究钢制连接中剪切板的厚度、开缝处小钢柱的高宽比、钢板强度及轴压比对RPW-HSC试件抗剪性能的影响,建立RPW-HSC抗剪承载力设计方法.结果表明:RPW-HSC试件的刚度与抗剪承载力随剪切板厚度、钢材强度及轴压比的增加而增加,但参数过大会导致该试件由钢制剪切板破坏转变为上部预制混凝土墙体破坏;当钢制剪切板开缝处小钢柱高宽比小于3时,试件的破坏由开缝处小钢柱的弯曲破坏变成上部预制混凝土墙体的剪切破坏.因此,需控制合理的设计参数以实现RPW-HSC试件结构损伤可控及震损可修复.RPW-HSC试件抗剪承载力设计方法获得的理论计算值与试验值及有限元结果吻合较好,验证了抗剪承载力设计方法的准确性.

Abstract ：
福建沿海地区石结构民宅保有量大，石结构抗震性能较差.石墙是石结构主要的承重及抗侧力构件，超高性能混凝土(UHPC)嵌缝加固石墙可提高石结构的抗震性能.为探究石墙经过UHPC嵌缝加固后石结构的整体抗震性能，采用LS-DYNA有限元软件分别建立了未加固石墙和UHPC嵌缝加固石墙的两种石结构模型，研究石结构地震破坏全过程，分析结构地震响应、破坏机制和抗震性能.研究结果表明：石结构在地震作用下呈现“竖向倒塌”的破坏模式.在PGA为55gal和110gal的工况下，未加固结构的损伤状态为轻微破坏和整体坍塌；加固后结构的损伤状态分别为基本完好和中等破坏.相比未加固结构，加固后的石结构基本周期略有降低，楼面峰值加速度降低了21.05%～25.26%;位移角减小了74.90%～94.50%,加固后石墙开裂得到有效抑制，结构损伤程度有所减小，加固效果明显.

Abstract ：
In order to characterize the mesoscopic seepage of pore spaces within undisturbed granite residual soil (UGRS). The 2D/ 3D pore models of UGRS were reconstructed using computed tomography (CT) scanning and image processing technology. The lattice Boltzmann method (LBM) was employed to simulate the seepage displacement process and water distribution in UGRS pores through programming. Results indicate that isolated pores have minimal impact on seepage outcomes. Only a few large, straight pores with good connectivity become dominant channels, generating preferential flow. Throughout the seepage process, the maximum velocity in the dominant passage shifts from the inlet to the middle and then to the outlet region. The influence of pore structure characteristics on seepage is more significant than pore proportion. Using industrial CT scanning technology and LBM provides a better description of real soil pore flow. The 2D model intuitively illustrates the preferential flow phenomenon of macropores, suitable for qualitative research. The 3D model, closer to reality, accurately calculates soil permeability, making it suitable for quantitative research. © 2024 Editorial Board of Journal of Basic Science and. All rights reserved.

Abstract ：
超高性能混凝土(UHPC)加固修复既有石结构中，UHPC与石材之间优异的黏结性能是保证加固效果的关键。因此，为探究UHPC-石材界面的黏结性能，通过劈裂抗拉试验和双L型剪切试验，考察不同界面处理方式对UHPC-石材界面黏结性能的影响。结果表明，UHPC-石材界面破坏模式主要分为三种，其中发生模式C破坏(石材UHPC破坏)时界面黏结强度最大。界面键槽处理方式能显著提高UHPC-石材界面黏结强度、界面剪切刚度，且在改变破坏形态的同时有效提升试件的延性，当键槽深度为20 mm时，试件表现出较好的界面黏结性能。另外，试件剪切荷载-位移曲线包含滑移前阶段和滑移后阶段，凿毛试件在滑移后阶段没有经历塑性变形。相同界面处理方式下，UHPC-石材的界面抗剪强度与界面劈裂抗拉强度呈正相关关系。

Abstract ：
为刻画原状土体内部孔隙细观渗流特征，选取东南沿海地区某地原状花岗岩残积土作为研究对象，基于计算机断层扫描(CT)和图像处理技术对2D/3D原状土体模型进行重构，并结合格子Boltzmann方法(LBM),通过自编程序模拟土体孔隙内水分渗流及分布情况.结果表明：孤立孔隙对渗流结果影响甚微，仅个别连通性好、孔径大且笔直的大孔隙会成为优势通道并产生优先流；渗流从开始至稳定过程中，最大流速主要出现在孔隙通道由宽变窄处，孔隙结构形态对渗流的影响较孔隙占比更为显著.基于工业CT扫描技术和LBM能较好刻画真实土体孔隙渗流特征，2D模型可更直观表现大孔隙优先流现象，适用于定性研究；3D模型更接近实际情况，可精确计算土体渗透率，适用于定量研究.

Abstract ：
The band gap characteristics of periodic structures provide a new idea for the field of seismic isolation in civil engineering，among which the one-dimensional periodic foundation structure has garnered significant attention due to its simple structure and economical applicability. In this paper，by studying the vibration characteristics of the one-dimensional periodic base structure，an approximate analytical solution for calculating the one-dimensional rubber-concrete periodic base band gap is derived，and on this basis，a one-dimensional rubber-concrete periodic foundation optimization design method based on the resonance zone of the superstructure is proposed. Numerical examples in the frequency domain and time domain show that the periodic foundation designed by this optimization method can ensure a good damping effect of its superstructure in a wide and continuous frequency range. © 2024 Nanjing University of Aeronautics an Astronautics.

Abstract ：
将钢渣混凝土灌入中空夹层钢管混凝土结构，充分利用钢渣混凝土的微膨胀性和中空夹层内外钢管对混凝土的约束作用，有效解决了钢渣混凝土工程应用中的安定性问题。以混凝土类型、空心率、支主管直径比和轴压比为参数变量，共进行了5个中空夹层钢管混凝土T形节点试件（1个普通混凝土试件、4个钢渣混凝土试件）拟静力试验研究。试验结果表明：与灌注普通混凝土相比，灌注钢渣混凝土对试件节点承载力影响不大，但位移延性和耗能能力明显增加，提高幅度分别达69.46%和48.20%；当空心率从0.3增大到0.5时，试件位移延性系数提高9.69%；当支主管直径比从0.40增大到0.68时，位移延性系数提高82.44%；当轴压比从0.1增大到0.2时，试件位移延性系数降低17.98%。建立有限元模型对试件的滞回性能进行了模拟，模拟结果与试验结果基本符合，验证了所建有限元模型的有效性。进而开展了节点承载力影响参数分析，得到最佳空心率为70%左右。钢渣在钢管混凝土结构中应用，可大幅提高其抗震性能。

Abstract ：
There is a lack of detection means for the isolation performance of the buildings built by passive control technology，so it is of great significance to test the dynamic characteristics of the isolated structures on the spot. A 4-story base isolation kindergarten was tested in the field，and the test device，method and results were displayed. The results were compared with the seismic structure model under the same conditions，and the dynamic response law and damping effect of the actual isolation structure were explored. The building was pushed away with hydraulic jack to produce 98 mm（corresponding to LNR500 shear strain 102%）hori-zontal initial displacement of the isolation layer，and concrete jacking rod was installed to support the building；The concrete rod was blasted with explosives and unloaded instantly to make the building vibrate freely；The dynamic response and other parameters were tested and analyzed. The results show that under the condition of horizontal initial displacement，the first-order natural vibration period of the isolated structure is significantly longer than that of the seismic structure，and the damping ratio increases；The hysteretic curve of the isolation layer is full；The dynamic response control effect of each floor is obvious，but the acceleration of the roof floor is slightly amplified compared with that of the bottom floor；After unloading，the isolation layer instantly resets，which shows that the isolation layer has rapid reset performance. © 2024 Nanjing University of Aeronautics an Astronautics.
