“…The high-performance construction material also gives rise to the development of the steel-concrete composite girders. Especially on the issue of ultra high-performance concrete (UHPC)-steel composite member, these researches mainly focus on the subjects: negative bending moment of steel-UHPFRC composite girders (Qi et al, 2020;Hamoda et al, 2017), flexural strength of UHPC-concrete composite members (Shirai et al, 2020). In addition, there are some findings on new type of composite girders, such as the post-installed shear connector aiming to strengthen composite bridge (Hällmark et al, 2019), bending capacity of U-shaped steel-concrete composite girders (Zhou et al, 2019) and straight-side U-shaped steel-encased concrete composite girders (Yan et al, 2021).…”

This paper has evaluated the bending performance of a novel prefabricated MVFT steel-concrete composite girder. 9 meters pilot MVFT girder was analyzed by validated finite element model. In the pilot test, the height of web, the length of grouted concrete in the girder and net spacing between webs were parametrically modeled to discuss their effect to the bending strength. An ultimate bending strength formula has been obtained, which was based on the regression of parametric results. In the meantime, the two Machine Learning (ML) models, BP neural network and Least Squares Support Vector Machine, have been also implemented to train and then predict the ultimate strength of MVFT girder. Three factors were selected as input in ML models: the distance between steel girder's Tensile Centroid(TC) and slab's Compressive Centroid(CC), the distance between steel girder's TC and its CC, the compressive area of steel girder. After the completion of the ML training, the ultimate strength predictions of 30 meters MVFT girder by BP model and the formula have been compared, which agrees well with each other and validates their accuracy.

“…The analysis of bearing capacity, stiffness and crack development demonstrated the preliminary feasibility and advantages of hybrid fibre ECC for steel–concrete composite girders. Hamoda et al [ 34 ] compared the mechanical properties of different materials in the negative moment region, namely NC, steel fibre-reinforced concrete and ECC. Compared with other specimens, the steel-ECC composite girder had superior cracking characteristics.…”

In order to improve the cracking performance in the negative moment region of composite continuous girder bridges with corrugated webs, engineered cementitious composite (ECC) is used instead of conventional normal concrete (NC). Web and concrete types are used as the main research parameters in experiments. The test results indicate that steel-ECC specimens have a higher flexural load capacity and stiffness than steel-NC specimens. The cracks of steel-ECC specimens are characterised by small width and dense distribution. Nonlinear finite element models are established and verified by experimental results. The simulated load–displacement curves are similar to the experimental ones, and the models have a high degree of accuracy. The ECC slab strength, thickness and width are used as parameters for the investigation to analyse the effect of the ECC slab on the flexural bearing capacity of composite girders. Compared with the results of calculations according to the code, the bearing capacity obtained from the parametric analysis is higher. It suggests that the contribution of the ECC slab needs to be considered when calculating the bearing capacity of the steel-ECC composite girder with corrugated webs.

“…Numerical models were also developed by researchers such as Chang et al [1], Wan and Zha [3], Liew et al [7], Ahmed et al [8][9][10][11][12], Ci et al [13][14][15] to investigate the nonlinear inelastic behavior of CFDST columns under different loading conditions. Furthermore, the composite action have been previously studied through hamoda et al [19][20][21].…”

Circular concrete-filled double steel tubular (CFDST) column offers improved strength and ductility compared to conventional concrete-filled steel tubular (CFST) column. This paper reports an experimental program carried out on short CFDST columns loaded either concentrically or eccentrically. The test parameters examine the influences of the eccentricity ratio and the diameter-to-thickness ratio of the steel tubes. The eccentricity ratio varied from 0 to 1.64 while the diameter-to-thickness ratio of the outer and inner steel tubes ranged between 43.8 to 54.75 and 32.57 to 45.6, respectively. It is observed that the tested columns failed in a ductile manner, however, an increase of the eccentricity ratio reduces the ultimate loads of the columns remarkably.
