Abstract ：
福建沿海地区现广泛分布着大量具有地域特色的石结构民宅,由于地理位置和经济条件的限制,部分民宅建造于软弱场地之上.目前建筑结构计算时地基通常采用刚性假定,而软土地基上建筑结构在地震作用下破坏更严重,因此亟需对此类石结构进行安全评估.选取一栋典型两层的软土地基石结构(SSI体系),设定地基土体等效剪切波速为147.57m/s,采用有限元软件LS-DYNA进行基于IDA的地震易损性分析,结果与刚性地基体系(FIX体系)进行对比,对其进行安全评估.结果表明:SSI体系较FIX体系更易于达到极限状态,结构地震易损性增加,概率差值可达40％～46％;基于易损性得出结构性能裕度比进行分析,SSI体系较FIX体系各极限状态下的性能裕度比均降低.研究揭示了坐落于软弱场地上的石结构较刚性地基体系破坏更为严重,成果为石结构的抗震加固提供依据.

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 ：
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 ：
In the coastal regions of Fujian,there are a large number of residential buildings constructed from stone,and they exhibits poor seismic resilience.Stone walls are the main load-bearing and lateral force resistant components of stone structures.Strengthening stone walls with UHPC infilled joints can improve the seismic performance of stone structures.To explore the overall seismic performance of stone structures after UHPC infilled joints,this study utilized the LS-DYNA finite element software to establish two distinct models of stone structures: one without reinforcement and another reinforced with UHPC infilled joints.The research aimed to investigate the complete seismic failure process,analyzed the seismic response,failure mechanisms,and performance of the structures. Findings reveal that the stone structure exhibits a 'vertical collapse' failure mode under seismic action.For PGA of 55 gal and 110 gal,the unreinforced structures exhibited minor to complete collapse, whereas the reinforced structures showed conditions ranging from minor damage to moderate destruction.Compared with the unreinforced structure,the fundamental period of the reinforced stone structure is slightly reduced,the peak acceleration of floor has decreased by 21.05% to 25.26%,and the displacement angle was reduced by 74.90% to 94.50%.The infilled joints reinforcement effectively curtailed stone wall cracking,mitigated structural damage,and significantly enhanced reinforcement effectiveness. © 2024 Editorial Board of Journal of Basic Science and Engineering.

Abstract ：
应用被动控制技术建成的隔震建筑，其隔震性能缺乏检测手段，因此进行隔震结构动力特性的现场测试具有重要意义。现场测试1栋4层基础隔震幼儿园，展示了试验装置、方法及所得结果，将结果与同条件下非隔震结构模型进行对比分析，探究实际隔震结构动力响应规律及减震效果。用液压千斤顶将建筑物推开使隔震层产生98 mm（对应LNR500剪应变102%）水平初位移，安装混凝土顶杆支撑建筑物；利用炸药将顶杆爆破卸载使建筑物做自由振动；最后测试和分析其动力响应等参数。分析结果表明：水平初位移条件下，隔震结构的一阶自振周期比非隔震结构显著延长，阻尼比增大；隔震层滞回曲线饱满；各楼层动力响应控制效果明显，但观察到屋顶层相比底层加速度略有放大；卸载后隔震层瞬间复位，表明隔震层具有瞬间复位特性。

Abstract ：
Plane irregular buildings are prone to torsion and cause serious damage to the structure. The analysis and control of structural torsion effect is the key to this kind of structural design. In this regard, the simulation calculation of the planar irregular multistory frame model in the 8-degree fortification zone was carried out, and the planar L-type four-story frame isolation model of five typical class B buildings was established. The ratios of the length B and width W of the protruding limbs of the structure were set to be 1:1, 1.5:1, 2:1, 2.5:1 and 3:1, respectively. The dynamic characteristics and seismic response of different structures were analyzed. The influence of the LRB stiffness ratio and the rigid center position of the isolation layer on the structural torsion was discussed, and the effective control method of structural torsion was proposed. The results show that with the increase of the length-width ratio B/W of the protruding limb, the X-direction torsion of the structure increases gradually, and the Y-direction torsion decreases gradually. Increasing the proportion of LRB stiffness can reduce the torsional effect of the structure. By comprehensively controlling the structural torsion and structural damping coefficient, a reasonable proportion of LRB stiffness can be obtained. The proportion of LRB stiffness of the isolation layer under the condition of 8 degrees earthquake is proposed. At the same time, the rigid center of the isolation layer and the rigid center of the superstructure are arranged on both sides of the mass center of the superstructure to suppress the torsion of the superstructure of the plane irregular structure. © 2024 Nanjing University of Aeronautics an Astronautics.

Abstract ：
为研究不同耗能机制的钢板阻尼连接对装配式钢框架梁柱节点力学性能的影响,本文对两个钢板阻尼连接的装配式边柱减震节点试件进行拟静力试验研究,获得试件的破坏模态、滞回曲线、骨架曲线、滑移曲线和应变发展情况,分析试件的承载力、延性、耗能能力、弯矩-转角等性能指标.研究结果表明:钢板阻尼连接的装配式边柱减震节点具有较好的承载性能和耗能性能,在试验过程中未发现梁、柱主体构件及节点核心区破坏现象,可将损伤集中控制于钢板阻尼连接处.耗能钢板圆形开孔的承压型钢板阻尼连接的装配式边柱减震节点(试件BSDC)主要为耗能钢板发生受拉破坏,长圆形开孔的摩擦型钢板阻尼连接的装配式边柱减震节点(试件FSDC)出现明显的滑移行为,在钢板阻尼连接处产生明显的弯曲残余变形.试件FSDC的承载力略低于试件BSDC,且由于往复荷载下的摩擦系数和预紧力损伤,加载后期试件FSDC承载力出现轻微下降,但其滞回曲线较为饱满,滞回行为稳定,而试件BSDC由于耗能钢板断裂导致承载力急剧下降.试件FSDC的耗能能力和延性均优于试件BSDC,摩擦型钢板阻尼连接耗能占比为88％,承压型钢板阻尼连接为67％,实现了集中耗能,钢板阻尼连接处的滑移行为可改善试件的耗能性能和变形能力.

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 ：
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 ：
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.
