Code and data for: A closed-form first-damage check for the column web-flange junction in cleated joints of pultruded FRP

This dataset contains the code and the extracted results that support every number and figure of the paper "A closed-form first-damage check for the column web-flange junction in cleated joints of pultruded FRP" (T.-T. Nguyen, manuscript submitted to Results in Engineering). The paper treats the column outstand of a web-cleated pultruded FRP beam-to-column joint as an orthotropic plate strip restrained by a rotational spring at the web-flange junction, solves it in closed form by a cosine transform, and assembles its influence functions with the steel cleat, the preloaded bolts and the unilateral contact of the cleat on the flange. Two first-damage limit states are checked: flexure of the wall beside the junction and tearing of the junction. The closed form is verified against a shell model of the column and an independent three-dimensional solid model of the isolated junction, the column with and without cohesive surfaces, and the complete joint with cleats, pretensioned bolts and frictional contact, and is applied to the tested joints of Qureshi and Mottram (2013, 2014). Contents:- code/closed_form: closed-form solution of the restrained orthotropic strip (Kirchhoff and Mindlin-Reissner), assembly with the cleat, bolts and contact, prediction of the first-damage moment, and Sobol' sensitivity analysis (Python).- code/shell: Abaqus scripts for the shell column (S8R), including the column-length, end-reaction and mesh-refinement studies.- code/solid: generator of the Abaqus input files for the solid model (C3D8I; configurations ISO, COL, CZM and JNT), output readers, batch scripts and post-processing.- code/figures: scripts that produce the figures of the paper.- data/solid_raw: extracted results of every solid analysis (transverse moment and stresses in the flange, force crossing the top of the web, deflections, cohesive initiation, joint rotation and bolt forces).- data/summary: summary tables (junction stiffness identified on isolated strips, closed form against solid model for 42 columns, cohesive initiation, full joints at the measured first-damage moment, shell mesh and end-reaction study).- data/closed_form and data/shell: output of the closed-form assembly and of the shell study. A README.md file describes the folder structure, the naming of the analysis cases, the units (N, mm, MPa) and the software requirements (Python 3 with numpy, scipy, pandas and matplotlib;Abaqus 2019 or later for the finite element models).
