The wood arch bridge has good seismic performance, and the “wood weaving” of its arch system is closely related. Wood weaving has the isolation function similar to that of rubber bearing isolation layer under earthquake, which is the key to ensuring good isolation performance of wood arch bridges. However, it is difficult to measure the seismic performance of the “wood woven” structure of the wooden arch bridge, which leads to its limited application. In order to solve this problem, building information model (BIM) technology is introduced into this field, and the application of BIM technology in the seismic performance of “wood woven” structures of wooden arch bridges needs research. First, the design principle of “wood weaving” is described, and then the seismic principle of “wood weaving” is analyzed. Finally, from the perspective of the structural strength index, the seismic performance of the wooden arch bridge “wooden woven” structure is analyzed in depth with BIM technology in order to provide some help for understanding the seismic performance of the wooden arch bridge “wooden woven” structure and promoting the effective application of wooden arch bridge.

Structural curved metal dampers are implemented in various applications to mitigate the damages at a specific area efficiently. A stable and saturated hysteretic behavior for the in-plane direction is dependent on the shape of a curved-shaped damper. However, it has been experimentally shown that the hysteretic behavior in the conventional curved-shaped damper is unstable, mainly as a result of bi-directional deformations. Therefore, it is necessary to conduct shape optimization for curved dampers to enhance their hysteretic behavior and energy dissipation capability. In this study, the finite element (FE) model built in ABAQUS, is utilized to obtain optimal shape for the curved-shaped damper. The effectiveness of the model is checked by comparisons of the FE model and experimental results. The parameters for the optimization include the curved length and shape of the damper, and the improved approach is conducted by investigating the curved sections. In addition, the design parameters are represented by B-spline curves (to ensure enhanced system performance), regression analysis is implemented to derive optimization formulations considering energy dissipation, constitutive material model, and cumulative plastic strain. Results determine that the energy dissipation capacity of the curved steel damper could be improved by 32% using shape optimization techniques compared to the conventional dampers. Ultimately, the study proposes simple optimal shapes for further implementations in practical designs.

“…Steel bridges are widely used in the regions with high seismic demands due to their excellent seismic performance (Li et al 2020;Liu et al 2021;Sui et al 2020b;Zhuge and Xie 2020;Zhuge et al 2022b), and steel circular hollow section (CHS) is one of the primary bridge pier shapes of steel bridges. In recent years, the analytical models (Goto et al 1998;Zhuge et al 2022a), seismic performance (Gao et al 1998a;Ge et al 1997;Sui et al 2020a), and ultimate strength (Chen et al 2019;Wang et al 2011;Yuan et al 2014) of steel bridge piers have been widely studied.…”

Steel circular hollow section (CHS) bridge piers have been widely used in the engineering practices. However, end corrosion is one of the most common damages to steel bridge piers, leading to degradation of seismic performance and changing of failure modes. This paper investigates the seismic performance of the corroded steel CHS bridge piers and proposes a method to predict its lateral ultimate strength under the transverse cyclic loads. Firstly, the multi-scale finite element (FE) models of the CHS steel bridge pier are developed considering both the local buckling and the end corrosion, which are calibrated against the previous test results. Subsequently, the effects of the characteristic parameters (i.e., the corrosion conditions and the column parameters) on the failure modes and the horizontal ultimate strengths of the corroded steel CHS bridge piers are investigated, and then the sensitivity of the parameters is quantified using the Sobol method. Finally, a method is presented for estimating the ultimate strength of the end corroded steel CHS bridge piers under the horizontal cyclic loads. Results show that the end corroded bridge piers exhibit more significant stress concentration when comparing with the uncorroded bridge piers. The buckling half-wavelength is influenced by corrosion parameters, and the buckling position changes. The ultimate strengths of end corroded bridge piers are reduced, which is more sensitive to the corrosion rate. The proposed theoretical method to predict the ultimate strengths of corroded steel CHS bridge piers is accurate enough with errors less than 10%.
