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 ：
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 ：
A new nanocomposite g-C3N4/CoAl-LDH was synthesized and implemented to make alkali-activated steel slagbased photocatalytic pervious concrete (ASSPPC). The water permeability, compressive strength, microstructure, and NOx degradation ability of ASSPPC were investigated. The results show that at lower dosages (1 wt% and 3 wt%), the spherical structure facilitates excellent dispersion of g-C3N4/CoAl-LDH within the matrix, which leads to reduced matrix porosity, resulting in improved compressive strength and reduced water permeability in ASSPPC. Compared to control previous concrete, the compressive strength of ASSPPC with 1 wt% g-C3N4/CoAl- LDH increased by 6.3%, and water permeability of which decreased by 15.4%, respectively. However, at higher dosages (5 wt%), g-C3N4/CoAl-LDH tends to agglomerate, causing lower hydration degree and higher matrix porosity. Moreover, owing to the remarkable alkali resistance of g-C3N4/CoAl-LDH, ASSPPC with this photocatalyst only marginally decreases its NOx degradation ability as the curing age increases. When considering water permeability, compressive strength, and NOx degradation ability, ASSPPC with 3 wt% g-C3N4/CoAl-LDH demonstrates optimal performance, which gives both compressive strength and water permeability equivalent to pervious concrete without photocatalyst while exhibiting a NOx degradation rate 0.58 times higher than that of ASSPPC with 3 wt% g-C3N4.

Abstract ：
This paper studied the axial compression behavior of the steel tube reinforced concrete (STRC) column, which consisted of inner CFST and outer RC components. Ten specimens, including seven STRC columns, two RC columns, and one CFST column were tested. The test parameters included the CFST area ratio (inner CFST to the whole section), longitudinal rebar ratio and stirrup space. The test results showed that the compressive behavior of STRC column with a CFST area ratio of 0.04 was close to that of the RC column, and the compressive behavior of the STRC column with a CFST area ratio of 0.13 was between that of the RC column and CFST column. The finite element (FE) models were developed and verified by test results to investigate the effects of longitudinal rebar ratio and stirrup space on the axial compression behavior of STRC column with various CFST area ratios. The load distribution between inner CFST and outer RC components was analyzed. The FE results showed that the effects of the longitudinal rebar ratio on the ultimate load of STRC column were related to the CFST area ratio. The accuracy and applicability of the five methods suggested by codes for predicting the ultimate load of STRC column were discussed based on the test and FE results.

Abstract ：
The development of probabilistic corrosion hazard maps for reinforced concrete infrastructure exposed to airborne chlorides in coastal regions is addressed in the present work, with special attention to bridges. The methodology developed in this study consists of three steps. Initially, spatial distribution, construction year, and main features of the existing infrastructure are examined together with the general characteristics of the study area. The second step deals with the elaboration of relevant environmental data, including the direction and height of sea waves, sea salinity, temperature, relative humidity, rainfall, speed and direction of wind, and chloride deposition rates. Corrosion hazard maps are obtained next, wherein the corrosion current density is selected as an intensity measure. Particularly, they are elaborated for an assigned probability of exceedance given the exposure time window and concrete mixture. The presented methodology is applied to develop probabilistic corrosion hazard maps for reinforced concrete bridges exposed to the marine atmosphere at Oahu Island (Hawaii, United States). For this case-study, it is also discussed the correlation between the actual condition rating of the existing concrete bridges and the estimated corrosion hazard levels.

Abstract ：
Nonlinear response time-history analyses are used in well-known seismic performance assessment methods such as Incremental Dynamic Analysis, Multi-Stripes Analysis and Cloud Method to describe the relationship between chosen Damage Measure versus Intensity Measure. Numerous researches have presented simplified procedures or nonlinear static procedures to develop fragility over the last two decades. In NSPs, pushover analysis is used to assess the system capacity, and response spectra quantify the seismic demand. In addition to the known ones, Incremental Modal Pushover Analysis (IMPA) is a novel nonlinear static procedure that has been proposed in recent years and is used in this study to advance an IM-based fragility estimation. The accuracy and effectiveness of various vulnerability assessment methods are investigated by comparing fragility curves obtained from MPA-based Cloud Analysis, IMPA, Cloud Analysis to IDA fragility curves. The results from two relatively small bins of record motions differing by ranges of Joyner-Boore Distance and are scattered across a range of Magnitude are presented. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Abstract ：
The research focused on the design of a curved shell-supported footbridge using a form-finding algorithm and genetic optimization. The bridge was shaped through a parametric design code, which also allows optimization based on finite element structural analysis. The constrained optimization involved a mono-objective approach aided by penalty functions to control the maximum tension utilization of the concrete material. The objective was to find the optimal bridge shape in terms of minimizing displacement under vertical and horizontal loads, with both the topological optimization of the positions of the bridge supports and the optimization of the control points of the Bezier curve describing the form of the curved deck as key parameters. The results provide insights into effective techniques for optimizing the design of curved shell-supported footbridges subjected to earthquake loads. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract ：
This study explores parametric design and optimization to improve a reciprocal frame bridge’s structural efficiency while preserving its historical and architectural significance. The research aims to identify an optimal configuration that minimizes steel requirements for a self-supported bridge while satisfying structural requirements. This objective was achieved by modifying the bridge’s geometrical parameters using a genetic algorithm for mono-objective optimization. A finite element structural analysis was conducted to evaluate the maximum stress in the material, with a penalty function used to ensure structural safety. The parametric design software allowed for efficient and precise optimization of the bridge design. The results demonstrate that the proposed optimization method reduces material usage while maintaining the bridge’s original structural concept of traditional wooden Chinese bridge, validating the approach’s effectiveness for future design of reciprocal frame bridges. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.
