TL;DR: In this paper, the in-plane behavior of built-up box beams with nested C section and U section under pure bending about strong and weak axis is investigated, and the reasonability of the capacity superposition method and equivalent method is assessed by the discussion on test results and numerical analysis results.
Abstract: Built-up sections are widely used in cold-formed thin-walled steel frames. This paper mainly investigates the in-plane behaviour of built-up box beams with nested C section and U section under pure bending about strong and weak axis. The four-point bending test was conducted on a total of 7 groups of specimens, including built-up box sections (CU) and individual sections (C, U). A finite element model is developed and verified by the test results for further parametric analysis. The stress distribution at mid-span cross-section shows that the components in built-up beams can resist the bending moment together. For built-up box beams bending about strong axis, the reasonability of the capacity superposition method and equivalent method is assessed by the discussion on test results and numerical analysis results. The equivalent box section is suggested to calculate the flexural strength of built-up box beams bending about weak axis. Finally, the comparison between predicted and actual flexural strength indicates that this simplification of the proposed method can slightly under-estimate the flexural strength.

TL;DR: In this paper, the authors evaluated the bending moment of a severely corroded box girder subjected to uniform vertical bending moment through a series of nonlinear finite element analysis and developed new stress-strain relations to account for the effect of corrosion on the flexural rigidity.

TL;DR: A finite element model of a poroelastic prismatic solid of rectangular cross-section is considered to simulate bone behaviour, precisely as in the previous work by Zhang and Cowin, to verify the accuracy of the simplifying hypotheses underlying the analytical solutions and provide further insight into the behaviour of that solid.

TL;DR: In this article, five reinforced concrete (RC) beams strengthened with Basalt Fiber Reinforced Polymer (BFRP) grid in conjunction with Engineered Cementitious Composite (ECC) were tested along with one conventional RC beam for reference to investigate their performance improvement, particularly in shear capacity.
