Abstract ：
矮塔斜拉桥通常采用对称悬臂法施工,客观条件可能导致该方法无法采用,需要研究非对称悬臂施工的可行性.文章针对双塔双索面预应力混凝土矮塔斜拉桥开展实桥监测,建立有限元模型,分析合理成桥状态和合理施工状态.考虑背景工程无法采用对称悬臂法的实际情况,基于合理施工状态提出边跨现浇段非对称悬臂施工的2种方案,对比采用2种方案完成边跨现浇段施工后对合理施工状态下主梁的挠度、应力及斜拉索索力的影响.结果表明:采用应力平衡法计算成桥恒载弯矩可行域,并以此为约束条件利用基于影响矩阵法原理的未知荷载系数法可计算合理成桥索力;利用考虑施工阶段的未知荷载系数法计算合理初张拉索力及二次张拉索力,可得到合理施工状态;与方案1相比,采用方案2的主梁最大挠度更小且分布更合理,边跨无索区主梁上缘拉应力更小,斜拉索索力分布更均匀;方案2对矮塔斜拉桥的合理施工状态影响较小,最终可达到合理成桥状态.

Abstract ：
Ultra-high-performance concrete (UHPC) is renowned for its exceptional strength and durability, but the undesirable high material cost due to the considerable expense of reinforcing steel fiber hinders its wide application. The incorporation of more sustainable and light synthetic fibers presents a promising avenue for lowering the price and weight of UHPC while affecting the rheological and hardened behavior of UHPC. This paper conducts a comprehensive review of the key parameters of synthetic fibers, including content, aspect ratio, and surface properties, and their impacts on the fresh properties, mechanical performance, durability, and volume stability of UHPC. Particular emphasis is placed on the early and long-term performance of UHPC. Additionally, the sustainability of UHPC with various types of synthetic fibers is compared. By delving into these aspects, this study aims to furnish a constructive reference for engineers and decisionmakers regarding the utilization of synthetic fibers in UHPC to achieve optimal early and longterm performance.

Abstract ：
This study investigates the optimization of gridshell dome shapes using seismic design demand parameters as the primary objective function. The innovative methodology integrates shape optimization with seismic analysis, deviating from traditional approaches that separate geometric design and seismic performance enhancement. By integrating computational methods, utilizing parametric modeling through Grasshopper, and structural analysis with OpenSees, the framework employs a genetic algorithm for optimization. Nonlinear time-history analysis, incorporating material and geometric nonlinearities, reveals that the optimal shape of the dome is significantly influenced by its seismic response. The results show that the optimal dome shape can vary substantially based on seismic performance criteria, indicating a dynamic interplay between structural form and seismic forces. Moreover, the optimal shape can be further influenced by implementing a supplementary damping system. In this case, both the gridshell shape and seismic dampers arrangement require adjustments to achieve optimal seismic performance. These findings highlight the critical role of integrated seismic analysis in shaping optimization, emphasizing that the ideal dome geometry is not static but evolves in response to seismic demands and damping configurations. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Abstract ：
Integral abutment bridges (IABs) generate strong soil-structure interaction (SSI) effects due to their high structural stiffness and transmission of inertial and thermal loads generated at the deck directly to the abutments. Despite an increasing number of experimental and numerical studies available in the literature, there is a lack of consolidated methodologies to model dynamic SSI phenomena for IABs, particularly in seismic regions where uncertainties associated with the induced ground motions render the problem harder to tackle. This study proposes an advanced strategy to model the seismic response of IABs, accounting for dynamic interaction between the structure, the abutment and the foundation, including piles and earth retaining walls. To this end, detailed finite-element studies were carried out employing OpenSees to simulate a recent experimental campaign on a scaled IAB model in a soil container (SERENA) carried out at EQUALS Lab, University of Bristol, in the framework of SERA/H2020 project. An extensive dataset in terms of recorded accelerations, displacements, strains and settlements are available from these tests, including earth pressures which are back-calculated from bending strain measurements. The objectives of this paper are threefold: firstly, the model parameters are explored and assessed critically by comparing the results from the numerical simulations against the experimental data; secondly, once the model is deemed sufficiently representative of the experiments, earth pressures are obtained numerically, as these are not directly measured in the tests; thirdly, the estimated static and dynamic earth pressures on the abutment wall are compared with the predictions of two simplified analytical procedures currently under consideration for inclusion in the new Eurocode 8. The results indicate that records and predictions match well for frequencies of up to 40 Hz at model scale (about 8 Hz in prototype scale) and confirm that the proposed modelling strategy can be used in practical applications. The quasi-elastic model proposed in this study is shown to provide dependable predictions for cases involving moderate strains in real-life applications.

Abstract ：
The steel slag and ground granulated blast furnace slag with high fineness exhibit synergistic effects on hydration progress and can be introduced into concrete in high volume. In this paper, the simulated pore solution (SPS) of ternary cement incorporating ultrafine steel slag (US) and ultrafine ground granulated blast furnace slag (UG) was prepared to examine the passivation behavior of the HRB400 reinforcing steel under SPS. It is found that the rapid growth of passive films occurs primarily within the initial 2-3 days after immersion in the SPS, while the compaction of passive films takes place mainly at the later stages. The open circuit potential and charge transfer resistance of the passive films initially increase and then decrease with the continuous rise in the US content. The Fe2O3 constitutes a significant portion of the passive films above the steels treated with the SPS irrespective of US dosages, whereas the content of FeO is highly influenced by US dosages. The UG-US-C pore solution could enhance the passivation behavior because of lower Ca2+ and higher Na+. In case of UG/US ratio at 2:3, the passive film exhibits the greatest thickness at 7.5 nm and meanwhile with the highest compaction and the least roughness.

Abstract ：
Integral abutment bridges (IABs) have been widely applied in bridge engineering because of their excellent seismic performance, long service life, and low maintenance cost. The superstructure and substructure of an IAB are integrally connected to reduce the possibility of collapse or girders falling during an earthquake. The soil behind the abutment can provide a damping effect to reduce the deformation of the structure under a seismic load. Girders have not been considered in some of the existing published experimental tests on integral abutment-reinforced-concrete (RC) pile (IAP)-soil systems, which may not accurately represent real conditions. A pseudo-static low-cycle test on a girder-integral abutment-RC pile (GIAP)-soil system was conducted for an IAB in China. The experiment's results for the GIAP specimen were compared with those of the IAP specimen, including the failure mode, hysteretic curve, energy dissipation capacity, skeleton curve, stiffness degradation, and displacement ductility. The test results indicate that the failure modes of both specimens were different. For the IAP specimen, the pile cracked at a displacement of +2 mm, while the abutment did not crack during the test. For the GIAP specimen, the pile cracked at a displacement of -8 mm, and the abutment cracked at a displacement of 50 mm. The failure mode of the specimen changed from severe damage to the pile top under a small displacement to damage to both the abutment and pile top under a large displacement. Compared with the IAP specimen, the initial stiffness under positive horizontal displacement (39.2%), residual force accumulation (22.6%), residual deformation (12.6%), range of the elastoplastic stage in the skeleton curve, and stiffness degradation of the GIAP specimen were smaller; however, the initial stiffness under negative horizontal displacement (112.6%), displacement ductility coefficient (67.2%), average equivalent viscous damping ratio (30.8%), yield load (20.4%), ultimate load (7.8%), and range of the elastic stage in the skeleton curve of the GIAP specimen were larger. In summary, the seismic performance of the GIAP-soil system was better than that of the IAP-soil system. Therefore, to accurately reflect the seismic performance of GIAP-soil systems in IABs, it is suggested to consider the influence of the girder.

Abstract ：
It is well established that, for tuned mass dampers, a high mass ratio relative to the protected structure is essential for effective performance under seismic excitation inmost scenarios. This paper proposes a novel method to enhance the seismic effectiveness of a tuned mass damper without increasing the mass ratio. The proposed approach introduces an innovative device in which a tuned mass damper is serially coupled with a vibro-impacting mass that slides with negligible friction before impacting the boundaries of its runway. This system is then connected to the first storey of the frame structure via a Kelvin-Voigt visco-elastic device. The study employs a dynamically equivalent four-degree-of-freedom model, with its governing equations derived through a direct formulation approach. Initially, the coupled system is subjected to harmonic excitation, and the resulting behaviour is represented using frequency-response curves, which depict the maximum displacements of the structure in relation to the excitation frequency. Following this, a subsequent analysis involves subjecting the system to three distinct earthquake records to evaluate its performance under seismic excitation. To evaluate the effectiveness of the proposed protective device in reducing the displacements of the frame structure during seismic events, the displacements of the first storey and the drifts of the superstructure are compared to those of a frame structure without the external device. The findings indicate that the proposed device performs effectively across a wide range of system parameters, proving to be especially effective for low- and medium-rise frame structures.

Abstract ：
Structural Health Monitoring (SHM) is one of the main approaches to deal with damage identification in existing bridges. Static information together with structure modal properties allow to prevent collapses, detect damage also in the early stage, and plan maintenance works based on the bridge condition. Measurement systems are traditionally composed of a network of sensors directly installed on the structure. Despite the large diffusion of these systems, the expensive and time-consuming installation of sensors and acquisition system makes their use not always feasible. A promising approach for the characterization of bridge dynamic behavior is represented by computer vision-based techniques, which require the sole installation of one or more cameras outside the structure, along with some targets on it when necessary. This approach is totally non-invasive, low-cost and enables the direct measurement of structural displacements, providing useful and direct information about the operational conditions and possible permanent deformations. With the aim of investigating the potential of vision-based techniques for the dynamic monitoring of structures, this paper presents preliminary results of dynamic tests performed on a steel footbridge. Structural vibrations caused by a jumping pedestrian were measured from a camera placed at the riverbed as well as by an accelerometer-based monitoring system installed for validation purposes. The post-processing of video recordings is here presented and discussed, with particular emphasis on the impact of target shape and camera shaking. © 2024 The Author(s).

Abstract ：
This paper presents the dynamic identification of the Ostiglia-Revere railway bridge, a steel truss girder bridge located in Northern Italy. The bridge is 6.6 m wide, about 940 m long and composed of 12 spans. The accelerations of a bridge span caused by both ambient excitation and train passages have been continuously measured from August to November. The monitoring system consists of 4 temperature sensors and 4 biaxial MEMS accelerometers, acquiring accelerations with a sampling frequency of 80 Hz. Modal properties are estimated adopting two different identification approaches, namely the Enhanced Frequency Domain Decomposition and the Stochastic Subspace Identification. Particular attention is paid to two crucial issues for vibration-based structural health monitoring: the recognition of the same structural mode from results identified during different time windows (i.e.; mode clustering), and the temperature effect on estimated modal properties. As the latter is concerned, two regressive models, namely a linear regression model and an ARX model, are fitted to the frequency-temperature data, strongly reducing the eventuality of false vibration-based damage detections in the future. © 2024 Elsevier B.V..
