“…Concrete arch bridge with Concrete-Filled Steel Tubular (CFST) stiffened skeleton is a type of composite bridge possessing the high bearing capacity and ductility and has been put into practice in the southwest area of China in recent year (Xie, 2012). Beipanjiang Bridge is one of the largest concrete arch bridges located in Shanghai-Kunming Passenger Dedicated Lines (Wang, Zhan, & Zhao, 2016). Its arch span is 445 m, and height is 100 m. The design speed is 350 km/h.…”

The reinforced concrete arch bridge with concrete-filled steel tubular stiffened skeleton is extensively used in the mountainous area of southwest China due to their long span and high stability. Beibanjiang Bridge located in Shanghai- Kunming high-speed railway, which had a record span of 445 m, has recently been completed in 2016. However, concrete creep and shrinkage have pronounced effects on the long-term deflection and stress redistribution of this bridge. Several concrete creep and shrinkage specimens in the natural environment were made to predict the long-term behaviour of this bridge accurately. They were used to measure the concrete creep and shrinkage of the core concrete and surrounding concrete used in the arch bridge. The test results were compared to ACI209 R-92 Prediction of Creep, Shrinkage and Temperature Effects in Concrete Structures model, 1990 CEB-FIP Model Code 1990: Design Code model, fib Model Code for Concrete Structures 2010 model and Creep and Shrinkage Prediction Model for Analysis and Design of Concrete Structures-Model B3. Based on the numerical fitting method, the fib Model Code for Concrete Structures 2010 model was modified to suit the concrete creep and shrinkage experimental results. Then, the modified fib Model Code for Concrete Structures 2010 model was used to predict the timedependent behaviour of a concrete arch bridge.

“…The stiffened skeleton is taken as the construction platform, OF ROAD AND BRIDGE ENGINEERING 2 0 1 9/ 1 4 ( 2 ) and the surrounding concrete was poured based on the platform (Wang, Zhan, & Zhao, 2016). The core and surrounding concrete whose properties used in this bridge was C80 and C60 concrete, respectively (Wang, Zhan, & Zhao, 2016). The main span of the arch is 445 m, and the rise is 100 m, so that rise to span ratio is 1/4.45.…”

This paper continues the previous study on clarifying the timedependent behaviour of Beipanjiang Bridge -a reinforced concrete arch bridge with concrete-filled steel tubular stiffened skeleton. The obtained prediction models and the Finite Element Models were used to simulate the long-term behaviour and stress redistribution of the concrete arch bridge. Threedimensional beam elements simulated the stiffened skeleton and surrounding concrete. Then, a parameters study was carried out to analyse the timedependent behaviour of the arch bridge influenced by different concrete creep and shrinkage models. The simulation results demonstrate that concrete creep and shrinkage have a significant influence on the time-dependent behaviour of the concrete arch bridge. After the bridge completion, the Comite Euro-International du Beton mean deviation of displacements obtained by 1990 CEB-FIP Model Code: Design Code model and fib Model Code for Concrete Structures 2010 model are 3.4%, 31.9% larger than the results predicted by the modified fib Model Code for Concrete Structures 2010 model. The stresses between the steel and the concrete redistribute with time because of the concrete long-term THE BALTIC JOURNAL OF ROAD AND BRIDGE ENGINEERING 2 0 1 9/ 1 4 ( 2 ) effect. The steel will yield if the fib Model Code for Concrete Structures 2010 model is used in the analysis. The stresses in a different part of the surrounding concrete are non-uniformly distributed.

“…However, the study excluded a comprehensive evaluation of the stability of arch bridges. To determine the thermal performance of a concrete box arch bridge, Wang [10] calculated the thermal field using the two-dimensional planar finite element model on the basis of the meteorological parameter method. Similarly, the study evaluated the three-dimensional beam finite element model of thermal stress and displacement of arch bridges on the basis of vertical temperature gradient.…”

Steel arches are widely used to construct main arches in modern concrete bridges. However, the applicability of existing steel arches has certain limitations. To expand the application scope of steel arches and enhance the material utilization rate, this study proposed a calculation and analysis model for a novel steel arch with an adjustable axis. First, the finite element calculation model of the arch structure was established using the finite element software Midas Civil based on Timoshenko beam theory. Second, the sensitive factors that affect the mechanical response characteristics of the novel arch, such as the connection method of the upper chord in the arch section, boundary conditions of the arch springing hinge, and temperature, were thoroughly discussed through calculation and analysis of engineering projects. Finally, the effect of span and width on the arch stability was discussed using the linear elastic analysis method. The mechanical response of the new steel arch was obtained, and the reliability of the calculation results was verified. Results demonstrate that a rigid connection is applicable to the upper chord connection of the arch section, and the two-hinged arch applies to the frame. Temperature changes can lead to obvious deformation and the decrease in temperature indicates a clear stress on the arch. Without considering wind load, the minimum wide-span ratio for the novel arch reaches 1:20. This study can provide a reference for application and calculation analysis of such arches.
