Combined web crippling and bending moment failure of first-generation trapezoidal steel sheeting

Deformation and failure of profiled stainless steel blast wall panels. Part III: finite element simulations and overall summary

“…Hofmeyer [13,14] investigated the combined web crippling and bending moment failure of corrugated sheeting subjected to a central point load. He performed 3 point bend experiments on a range of corrugated sheet geometries and simulated their behaviour using analytical modelling and the FE package ANSYS.…”

“…He performed 3 point bend experiments on a range of corrugated sheet geometries and simulated their behaviour using analytical modelling and the FE package ANSYS. Hofmeyer found that correctly modelling the bend radius of the corrugated sheets improved the numerical predictions and recommends using more than one shell element to model a bend radius [13,14].…”

“…The shell elements were approximately square with a nominal side length of 4 mm, to preserve a side-length aspect ratio of unity, and to maintain a suitable element length to thickness ratio. Two elements were used to model each bend radius, as recommended by Hofmeyer [13]. Static stress analyses were performed and a small damping factor (equivalent to 2 Â 10 À4 of the change in strain energy during the step) was applied to the model according to the defaults in ABAQUS [15].…”

Prediction of web crippling strength of cold-formed steel sheetings using neural networks

“…Their studies were developed by Hetrakul and Yu (1978) [6] and Yu (1981) [7] at Missouri-Rolla, which was used in specifications in USA. The experimental studies [8][9][10][11][12][13][14][15][16][17][18][19] on sheetings, sheet sections, and hat sections can be divided into three groups: 1. Members loaded by a pure concentrated load and a negligible small bending moment.…”

“…As various codes are compared, (the code used in the United States of America (AISI 96) [34], the code used in Europe (ENV 1993-1-3 Eurocode3) [35], and the code used in Canada [36]) the ultimate concentrated load prediction R u , can differ between +18% and −58%, which indicates that design codes do not give realistic results for the prediction of web crippling strength of sheetings [37].…”
