“…They advocated for exploring global 3D temperature effect numerical simulations and optimizing the placement of temperature sensors based on the boundary conditions required by the numerical simulations. Shan et al (2023aShan et al ( , 2023b established a global three-dimensional finite element model of the Qingzhou Bridge. They used transient heat conduction analysis to calculate the detailed temperature distribution throughout the entire bridge for all four seasons which found that the horizontal displacement of the bridge towers and the longitudinal displacement of the bridge ends are primarily affected by the average temperature.…”

Expansion joints play a crucial role in accommodating the longitudinal movement of the main beam, which is mainly caused by temperature variation. This paper establishes an accurate model that relates the temperature field of the main beam to the displacement of the expansion joint, enabling reliable performance prediction and early warning of the expansion joint. Firstly, three commonly used methods for characterizing the temperature field of the main beam are introduced, along with their advantages and disadvantages. Secondly, a novel method is proposed using the Lasso algorithm to calculate critical temperatures. The objective is to select temperature channels data that have significant impact on the longitudinal displacement of the main beam. The selected channels data is then linearly weighted based on feature importance to obtain critical temperature. Based on this, a precise relationship model between the main beam temperature and the expansion joint displacement is derived through regression. For the residual term in the model fitting, an expansion joint performance early warning procedure is developed based on the X-bar control chart. Finally, using one-year long-term monitoring data from a newly constructed cable-stayed bridge as an example, the proposed method demonstrates superior capability in predicting the predefined damage of the expansion joint compared to the other two commonly used methods.

“…Investigating the Qingma suspension bridge spanning 2132 meters, Xia et al (2013) combined numerical analysis with field monitoring to study temperature distribution and response. Shan et al (2023aShan et al ( , 2023b analyzed the global temperature field of a long-span cable-stayed bridge across different seasons, integrating heat transfer analysis and field monitoring data. They proposed a method for uniformly calculating temperature responses, highlighting the significant impact of temperature changes in tension cables, where the temperature stress ratio to the constant load stress of the main girder reached 96%.…”

The unique structural design of an arch ring featuring varying inclination angles for individual segments causes variations in the longitudinal distribution of the temperature field d along the arch axis. This study aims to enhance the understanding of temperature fields in reinforced concrete (RC) arch bridges with diverse arch ring structural configurations during their construction phases. A comprehensive investigation into the three-dimensional distribution pattern of solar-induced temperature fields within arch ribs during the construction of RC ribbed arch bridges was conducted. A field test specifically measuring the temperature distribution across arch rib cross-sections was conducted on-site, involving an RC arch bridge constructed using the cable-stayed cantilever cast in situ method. Analyzing the monitored on-site temperature data revealed the distribution characteristics of temperature fields at the arch foot cross-section under solar radiation. By comparing these findings with international standards, a vertical temperature gradient fitting model for arch rib cross-sections under solar radiation was formulated. Drawing upon meteorological records and solar radiation principles, an adaptive numerical simulation finite element model was developed to depict the temperature field within an arch rib section. This model was rigorously verified. Subsequently, a comprehensive analysis of the three-dimensional temperature field of the arch rib under solar radiation was performed. Additionally, a three-dimensional temperature gradient fitting model was proposed, accounting for the longitudinal inclination of the bridge.

“…The structural members in the cable-stayed suspension bridge are introduced in Figure 1 . Compared with suspension bridges, the cable-stayed suspension bridges have higher structural rigidity [ 1 , 2 ]. Compared with cable-stayed bridges, the cable-stayed suspension bridge provides better stability because of the lower compressive force caused by bridge decks.…”

“…Gimsing [ 1 ] has introduced the history and development of this type of bridge and provided detailed description of the two categories of this combined system: Roebling’s structural system and Dichinger’s structural system. Sun et al [ 2 ] presented a four-step approach for determining the finished dead load state of a cable-stayed suspension bridge during the design stage by combining a finite element analysis with an iterative numerical method.

Analytical Model for Early Design Stage of Cable-Stayed Suspension Bridges Based on Hellinger–Reissner Variational Method

et al. 2022

The cable-stayed suspension bridge is one type of bridge that has been increasingly applied to bridge engineering, especially in cross-sea projects. However, the complex combined system of this type of bridge makes it quite difficult for researchers to make a quick decision of the parameter values during the design stage. The Hellinger–Reissner method is applied here to analyze the deformation and force of the structural members in the bridge. The advantage of this method is that the solving of deformation and force is independent of each other, which would enhance the accuracy of the final results. Different load conditions are also considered in the analysis. The results from the present method are compared with test results and finite element analysis, and show good agreements. It implies that the Hellinger–Reissner is a comparatively more efficient method to help designers choose the key parameters for cable-stayed suspension bridges.
