These beams remain vulnerable to web-post buckling (WPB), requiring accurate prediction of WPB buckling capacity and verification of analytical design models. A validated finite element dataset of 10,764 web-post models is used to train and test ANN, SVR, and GEP, and to propose new ML-based design models compared against numerical and existing analytical methods.","City Research Online  \nCity, University of London Institutional Repository  \nCitation: Rabi, M. , Jweihan, Y.

However, these  \n29 sections are susceptible to web-post buckling (WPB) failure mode and therefore it is  \n30 imperative that an accurate design tool is made available for prediction of the web- 31 post buckling capacity. Therefore, the present paper aims to implement the power of  \n32 various machine learning (ML) methods for prediction of the WPB capacity in HSS  \n33 beams with (EBW) openings and to assess the performance of existing analytical  \n34 design model. For this purpose, a numerical model is developed and validated with  \n35 the aim of conducting a total of 10764 web-post finite element models, considering  \n36 S460, S690 and S960 steel grades. This data is employed to train and validate  \n37 diffe","cbCaisBUXZIpz7O8","https://ap.wps.com/l/cbCaisBUXZIpz7O8","pdf",8424453,1,55,"English","en",105,"# Abstract\n# Keywords\n#
