Abstract ：
The adaptive finite element limit analysis (AFELA) method was employed to simulate the active failure mechanisms and plastic region distribution properties under complex backfill conditions to study the active earth pressure of backfill near a firm slope on gravity walls rotating about the bottom. The simulation results revealed that the backfill progressively fails from top to bottom and the backfill in the area above the failure surface enters a plastic state. The slip -line method was combined with the pseudo -static technique to compute the seismic active earth pressure. Compared with the traditional limit analysis method and limit equilibrium method, the seismic slip line method does not need to pre -assume the failure mechanisms. The reliability and rationality of the method are confirmed by comparing the computation results of the seismic slip line method with the computation results of the finite element limit analysis method, the existing experimental data, and the existing theoretical solutions. Furthermore, the impacts of parameters such as backfill geometries, seismic acceleration, and interface strength on seismic active earth pressure are discussed in detail.

Abstract ：
The traditional reinforced concrete canopy using cast-in-place (CIP) technology, is associated with problems such as long construction period, high environmental pollution, and low construction quality. Prefabricated assembly technology, due to its modern and highly industrialized characteristics, provides a promising solution to address the mentioned challenges. In this study, an innovative Ultra High-Performance concrete (UHPC)-filled grouted corrugated duct connection (UGCDC) approach was introduced for prefabricated canopy beam-column joints, considering the structural characteristics of the canopy. To evaluate the seismic behavior of canopy beam-column joints utilizing the UGCDC method, three comprehensive full-scale quasi-static experiments were conducted. Meanwhile, relevant seismic behavior indexes were extracted from the hysteresis curve, and the seismic performance of canopy joints was assessed by analyzing the effects of different research parameters on seismic behavior indicators. In addition, based on the OpenSees platform, a fiber finite element model (FEM) was established that incorporated the bond-slip behavior at the UGCDC joint. The research results indicated that the seismic behavior of canopy beam-column joints using UGCDC is basically consistent with that of CIP joints, and setting a shear key in UGCDC joints can improve ductility by 22.4 %. In terms of bearing capacity, there is not much difference among the three specimens, but in terms of initial stiffness, the specimen using UGCDC and shear key and the specimen using UGCDC have increased by 6.0 % and 9.6 % compared to CIP specimen, respectively. The developed FEM can predict the hysteresis characteristic of canopy joints using UGCDC. UGCDC method is a reliable connection form for canopy beam-column connection joint, which is suitable for medium to high intensity earthquake areas. Finally, a seismic performance assessment method of prefabricated canopy beam-column joints using UGCDC was proposed. © 2024 Elsevier Ltd

Abstract ：
由于基坑开挖过程存在大量的不确定性，其支护结构在设计阶段无法根据现场环境的变化进行实时变形可靠度分析与预测.围护结构分布范围大，失效位置不可预测.工程监测数据由于监测点数量的限制难以直接反映围护结构连续变化的状态.采用穿越率法，提出一种适用于以地下连续墙为围护结构的深基坑工程的侧向变形预测与分析模型.利用MATLAB建立自适应指数平滑模型，自动计算和预测深基坑围护结构在不同深度的侧向变形.对比实测与预测的侧向变形数据，结果表明该自适应指数平滑模型在短期预测中具有精度较高、误差波动小的特点；同时采用预测数据的超越概率分析表明，深基坑侧向变形的分析模型同样适用于由自适应指数平滑法获得的预测数据，且随着位移限值远离最大监测位移值，分析精度将逐渐提高.通过利用椭圆搜索模式的反距离加权插值法，解决了样本点仅集中分布于深度方向的缺点，使插值结果更加平滑，结合基于深基坑侧向变形的分析模型，实现了围护结构空间曲面的变形预测，使评价反馈方式更加直观简洁.

Abstract ：
为研究三种纤维混杂对高韧性水泥基复合材料(ECC)弯曲性能的影响，将聚乙烯(PE)纤维与钢纤维(SF)、玄武岩纤维(BF)混杂，通过21组四点弯曲试验，分析试件的受力、破坏过程及不同混杂纤维掺量对弯曲性能的影响，并将弯曲性能试验结果与拉伸性能试验结果进行比对，得到混杂纤维ECC的弯、拉对应关系。研究结果表明：与单掺PE相比，复掺纤维可有效提高ECC的弯曲极限强度，但会损失一定程度的延性。钢纤维掺量对延性性能影响较大，建议钢纤维掺量不超过0.4%,且总纤维掺量不超过2.3%。玄武岩纤维对混杂纤维ECC起到良好的增强、增加延性作用。基于弯-拉关系得到的极限拉伸应变与试验值吻合良好，因此四点弯曲试验可以代替单轴拉伸试验来评价混杂纤维ECC的力学性能。

Abstract ：
为解决组合箱梁横向裂缝对结构安全的潜在影响，利用ABAQUS程序建立钢-工程水泥基复合材料(Engineered Cementitious Composite,简称ECC)组合箱梁的数值模型，揭示钢-ECC组合箱梁在受力过程中剪力滞的变化，并分析剪力滞效应的影响因素。研究结果显示，随着荷载增大，钢-ECC组合箱梁的剪力滞效应逐渐加剧，但当ECC翼缘板应变达到极限状态时，剪力滞效应开始趋于稳定。通过适当降低翼缘板的宽度与厚度，或增大箱梁腹板的高度，可以有效减轻钢-ECC组合箱梁的剪力滞效应。相较于两点对称荷载，集中荷载会导致更大的剪力滞效应。

Abstract ：
Socket connection is commonly used for connections between precast components, which has the advantages of good integrity and high construction fault tolerance. To further investigate the bond -slip behavior and improve the engineering design of Ultra High -Performance Concrete (UHPC)-filled concrete -filled steel tube (CFST) column -beam socket connections, this paper conducted bond -slip experiments on UHPC-filled CFST socket connections (UCSC) with different parameters (socket depth, presence of studs) to reveal their bond -slip properties. In addition, to conduct further parametric analysis, a reliable finite element model (FEM) of the UCSC joint was developed. Based on the experimental data and finite element analysis (FEA) results, a simplified calculation equation and a normalized bond -slip relationship model was established to estimate the bond -slip performance of UCSC. The research results suggested that the bond -slip behavior of the UCSC was sensitive to the socket depth, the presence of studs and the diameter of CFST. The FEM is capable of estimating the forcedisplacement relationship and the damage distribution of the UCSC joint under vertical loads. The developed simplified equation and normalized bond -slip relationship have been validated, and can be employed to predict the ultimate bonding bearing capacity and the bond -slip relation of UCSC joints, respectively. Finally, design recommendations were proposed for the engineering design of UCSC. The UCSC method is required to ensure a socket depth at least 1.0 D and a certain number of shear studs to connect the column -beam joint.

Abstract ：
This paper presents the dynamic response analyses of a special long-span cable-stayed bridge with the main span length of 680 (m) subjected to pulse-type ground motions. The 1/100 scaled shaking table test are developed herein to verify the accuracy and correctness of the 3D finite element (FE) model of the examined long-span cable-stayed bridge on the software platform of SAP2000. To systematically investigate the influence on the seismic responses and on the selection of the nonlinear viscous damper parameters of the employed long-span cable-stayed bridge both the near-fault pulse-type ground motions and the far-field ground motions are selected as the seismic inputs of FE model. Some important conclusions are drawn that the near-fault ground motions usually causes the larger peak responses (e.g., Tower top displacement, girder end displacement, and moment of tower bottom) of the long-span cable-stayed bridge compared with the far-field motions, namely the near-fault ground motions are more destructive to the structures. The displacement responses can be amplified approximately 2-3 times and the damper parameters (Damping coefficient C and damping index alpha) of nonlinear viscous dampers can be affected by the ground motion characteristics. The damper parameter values are changed from the C = 3000 and alpha = 0.3 in far-field earthquakes to the C = 6000 and alpha = 0.2 in near-fault earthquakes, namely the near-fault ground motions obviously increase the demand of energy consumption of general nonlinear viscous dampers.

Abstract ：
The cracking moment and deflection of prefabricated bridge deck panels (PBDPs) with connections are the critical indexes to assess their crack resistance and reliability. This paper presented improved prediction models for estimating the flexural performance, especially cracking moment and deflection, of PBDPs connected with CFRP tendons and UHPC grout. Afterwards, comparisons between experimental data and predicted cracking moment, moment capacity, and moment-deflection curves showed desired agreement. In addition, a finite element (FE) model was established and its reliability was verified by the comparison of moment-deflection curves between the FE model, predicted results, and tests. A parametric study was conducted to evaluate the influence of design parameters on flexural performance. The results show that the existing equations in the literature for calculating the effective moment of inertia cannot accurately predict that of PBDPs with novel connections. The improved performance prediction models have reasonable accuracy for flexural performance, including cracking moments, flexural capacity, and moment-deflection responses. The diameter and initial stress of CFRP, as well as concrete strength, have a positive influence on the performance of PBDPs connected with the proposed connections under bending moment.
