Abstract ：
To study the effect of stirrup confinement on the axial compressive bearing capacity of ultra-high-strength con⁃ crete (UHSC) precast columns, this paper first conducted an axial compression contrast experiment between full-size UHSC column and ordinary column, and investigated the difference of crack development, failure pattern and ultimate bearing ca⁃ pacity of these two type columns. Based on the experimental results, further finite element analysis was conducted to simu⁃ late 36 full-scale UHSC columns. The study focused on analyzing the effects of stirrup configuration, stirrup spacing, and stirrup diameter on the axial compressive performance of UHSC columns. Combining the experimental findings and para⁃ metric analysis results, a modified calculation formula for the axial compressive bearing capacity of UHSC columns con⁃ sidering stirrup confinement was proposed. The proposed formula was then compared with the calculation formula in the current Code for Design of Concrete Structures. The results show that: the ultimate bearing capacity of equal-strength de⁃ signed UHSC column is higher than that of ordinary concrete column, but it is more brittle than ordinary concrete, espe⁃ cially when reaching the ultimate bearing capacity; the confinement effect of stirrups on the core concrete enhances the axial compressive bearing capacity of UHSC columns. Changes in stirrup configuration, stirrup spacing, and stirrup diameter have a significant impact on the ultimate bearing capacity and peak compressive strain of UHSC columns; the proposed axial compressive bearing capacity correction formula for UHSC columns incorporates the differences between UHSC columns and ordinary concrete columns, considering the confinement effect of stirrups on the core concrete. Compared to the calcu⁃ lation formula provided in the code, which does not account for stirrup confinement and is primarily applicable to ordinary concrete columns, this formula better utilizes the material’s potential while ensuring safety margins. It can serve as a useful reference for practical engineering design. © 2025 South China University of Technology. All rights reserved.

Abstract ：
为探析箍筋约束作用对超高强混凝土柱轴压承载力的影响,先开展了足尺的超高强混凝土柱和普通柱轴心受压破坏对比试验,研究了超高强柱与普通柱在裂缝开展规律、破坏形态及极限承载力上的不同.并在此基础上,结合试验结果进一步开展有限元分析,继续针对36个超高强混凝土足尺柱进行了模拟,重点分析了箍筋形式、箍筋间距、箍筋直径等参数对超高强混凝土柱轴压性能的影响,结合试验结果和参数分析结果提出了考虑箍筋约束作用的超高强混凝土柱轴压承载力修正计算公式,并与现行《混凝土结构设计规范》的计算公式进行了对比.结果表明:按等强设计的超高强混凝土柱比普通混凝土柱具有更高的极限承载力,但比普通混凝土柱具有更大脆性,达到极限承载力时材料破坏比普通混凝土柱更为明显;箍筋对核心区混凝土产生的约束作用对超高强混凝土柱的轴压承载力起到了提高作用,改变箍筋形式、箍筋间距、箍筋直径对超高强混凝土柱的极限承载力以及峰值压应变会有较明显的影响;该文提出的超高强混凝土柱轴心受压承载力修正计算公式,结合了研究得出的超高强混凝土柱与普通柱的区别,考虑了箍筋对核心区混凝土的约束效果,相比规范所提的未考虑箍筋约束且主要适用于普通混凝土柱的计算公式,更能在保证安全余度的前提下充分发挥材料的作用,可为实际工程设计提供参考.

Abstract ：
For through tied-arch bridges, the corrosion and degradation of the cable's load-bearing capacity are the main external causes of cable breakage and subsequent structural failure; nevertheless, the progressive collapse after cable breakage is primarily attributed to the weak structural robustness, which makes a huge potential risk of bridge operation and maintenance (O & M). Whereas, as the basis of O & M, current condition evaluation method has not yet taken into consideration the influence of different consequences of cable breakage, resulting in unscientific conclusions for O & M decisions frequently. In this study, a robustness-based condition evaluation framework for the overall structure of the through tied-arch bridge is presented, consisting of three stages: (1) structural robustness assessment associated with tie-bar and suspender failure respectively; (2) classification of evaluation process by the results of robustness assessment, within which the overall structure is either evaluated using the code method or evaluated directly as unqualified (Condition I and II), or the structural member weightings are adjusted according to the robustness weightings (Condition III); and (3) condition evaluation of entire bridge. The evaluation processes of three conditions are further presented in accordance with the tied-arch structure and suspended deck system. To establish the robustness weightings in Condition III, the safety redundancy indexes of through tied-arch structures as well as the suspended deck system are calculated separately, combined with robustness assessment result. Applying the proposed framework to evaluating the condition of a through tied-arch bridge with different structures, the analysis and comparison indicates that, due to the robustness of the through tied-arch structure and suspended deck system, the variation in the potential risk of accidents induced by cable failure is shown intuitively through the evaluation results, which better meets the needs of guiding bridge O & M decisions consequently.

Abstract ：
Compared with those of other bridge types, the structural system of through tied-arch bridges is particularly susceptible to failure owing to the deterioration and fracturing of tie-bars as well as a lack of structural robustness, which are the main internal and external causes of progressive collapse accidents, respectively. In particular, low structural robustness strongly influences the severity of accidents induced by tie-bar breakage. To objectively reflect the possible failure mode induced by tie-bar failure and to provide improved structural robustness in through tied-arch bridges, within which the suspended deck system is relatively independent, a robustness assessment framework considering tie-bar failure is proposed in this study, by considering the design and maintenance essentials. First, the main analysis parameters for the extreme-event limit state considering tie-bar failure are put forward, including the critical tie-bar failure rate, partial factor for load effects, transverse reduction factor of multilane loading, dynamic magnification factor of material strength, and reduction factors of residual strength. Second, the quantitative assessment index of structural robustness I-T,I-rob is proposed based on the safety redundancy of the remaining structural members, and robustness assessment rules are put forward in accordance with the different calculation results of I-T,I-rob and horizontal displacement. A typical rigid-framed through tied-arch bridges is assessed using the proposed framework. The assessment results reveal that multiple fortifications against extreme events of tie-bar failure can be established by designing the tie-bars and the piers with sufficient safety features to form the first and final line of defense against the tie-bar breakage effect. Moreover, proper maintenance should be conducted to guarantee the structural robustness of bridges in use. The methodology is well suited for the design of new through tied-arch bridges and to access the robustness of existing bridges to ensure the safety of transportation services.

Abstract ：
Tie bars on through tied arch bridges are often in poor condition and may serve as an external cause of a tie-bar failure accident; nevertheless, bridge structural robustness contributes greatly in resisting progressive collapse, and poor robustness tends to be the essential internal cause of possible accident. To study the dynamic effect of tie-bar failure of a through tied arch bridge and to reveal the mechanism of how structural robustness reduces dynamic effects, a finite-element model of a typical rigid-frame through tied arch bridge is developed based on the most adverse tie-bar breaking time, a transient-unloading method with equivalent load is adopted to analyze the dynamic response of tie-bar failure, and the results under different working conditions are compared. Furthermore, parameter analysis of the arch-to-pier stiffness ratio is conducted for the dynamic-amplification effect. The results indicate that both the pier and the arch rib have significant dynamic-amplification effects with respect to tie-bar breakage, and the remaining tie bars are the most vulnerable elements of the bridge; thus, they should be considered the most important elements when conducting tie-bar failure analysis; the most adverse breaking time adopted in cable breakage analysis can be taken as 0.01 T; a greater arch-to-pier stiffness ratio is beneficial to reduce the dynamic response brought on by tie-bar breakage; therefore, a rigid-frame through tied arch bridge should be designed with a large pier thrust stiffness, while a simply supported tied arch bridge should not be used in future through arch bridges, and existing ones should be retrofitted as soon as possible.
