Abstract ：
在保证对结构变形、抗震性能改进效果的情况下，采用分段摇摆墙的形式可有效降低摇摆墙自身的内力需求，并且该形式具有制作更简单、运输更便利、安装更简易的优势。为了分析摇摆墙采用分段形式后对摇摆墙内力的改进效果，文中结合分段摇摆墙的特征及与整段摇摆墙不同的边界条件，推导了铰接分段摇摆墙-框架结构的位移和摇摆墙内力的简化计算公式，并进一步开展了摇摆墙刚度比和摇摆墙分段数目对摇摆墙内力的影响效果分析，且与整段摇摆墙的相应情况进行了对比。研究结果表明：将摇摆墙分段可以大幅降低摇摆墙的内力峰值、缩小内力值的变化区间，在均匀荷载作用时各分段摇摆墙的弯矩和剪力分布规律类似，且整段摇摆墙的弯矩峰值是分段摇摆墙的m2倍、整段摇摆墙的剪力峰值是分段摇摆墙的m倍，而在倒三角形荷载作用下时，上段分段摇摆墙的弯矩和剪力比下段分段摇摆墙的大；刚度比在1.0～5.0这一适当的区间内变化时，刚度比对摇摆墙内力的影响效果明显，且影响程度随摇摆墙刚度比增大呈先增大后减小的规律，但当摇摆墙刚度比在此适当区间之外（无论取值过大还是过小），摇摆墙内力改变情况则对刚度比变化变得不敏感，此时刚度比对摇摆墙内力的改善效果不佳；分段摇摆墙内力幅值的降低幅度会随着分段数目的增加而减小，在采用分段摇摆墙时分段数目不宜过多。除此之外，通过分析还可得，刚度比与分段数目这两个参数对摇摆墙内力的影响效果相对独立，影响效应不耦合。

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 ：
Using multiple rocking sections system can effectively reduce the internal force demand of the rocking wall itself while ensuring the improvement of structural deformation and seismic performance. This form also has the advantages of being easier to manufacture, transport, and install. In order to analyze the improvement effect of multiple rocking sections system on the internal force of the rocking wall, the paper derived a simplified calculation formula for the displacement of frame structure in multiple pinned rocking wall system and internal force of multiple pinned rocking wall by combining the characteristics of segmented rocking walls and different boundary conditions from rocking at base only system. And it further analyzed the influence of the rocking wall stiffness ratio and the number of rocking sections on the internal force of the rocking wall, which was compared with the corresponding situation of rocking at base only system. The research shows that the peak value and variation range of internal forces can be significantly reduced when setting multiple rocking sections over the height of rocking system in comparison to full slice rocking system. Under uniform distributed load, the distribution regularities of bending moment and shear force of each section of rocking wall in multiple rocking sections system is similar. Furthermore, the peak bending moment of the rocking wall in rocking at base only system is m2 times that of the rocking wall section in multiple rocking sections system, and the peak shear force of the rocking wall in rocking at base only system is m times that of the rocking wall section in multiple rocking sections system. However, when subjected to inverted triangle load, the bending moment and shear force of the upper rocking wall section are larger than those of the lower rocking wall section in multiple rocking sections system. The influence of stiffness ratio on rocking wall internal forces is obvious when the ratio varies in an appropriate scope of 1. 0~5. 0. When the stiffness ratio increases in this scope, the influence extent increases first and then decreases. When the stiffness ratio is not in this scope, whether too large or too small, the internal force of rocking wall is not sensitive to this parameter. At this point, the improvement effect of the rocking wall internal force by the stiffness ratio is not significant. The decreasing amplitude of rocking wall internal force decreases with the increase of the number of rocking sections, so when using multiple rocking sections system, the number of rocking sections should not be too large. In addition, the analysis also shows that the influence of the stiffness ratio and the number of rocking sections on the internal force of the rocking wall is relatively independent, and the influence effects are not coupled. © 2023 South China University of Technology.

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.
