The empirical formulation's applicability and accuracy were verified by comparing the nonlinear finite element method (NLFEM). In total, 700 cases of initially deflected plate scenarios by assuming the buckling mode shape were adopted as the input data. For the simplification of the plate design process, a general shape of the empirical formula is proposed based on input data. A reliable technical solution is obtained with good agreements (R2 = 0.98 to 0.99) compared to NLFEM. The advantage of the proposed outcome is documented by comparing the previous study. The obtained result could be beneficial for the structural design of the initially deflected plate in predicting its ultimate strength performance under longitudinal compression. © 2022 Elsevier Ltd date: 2022 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85128231048&doi=10.1016%2fj.oceaneng.2022.111151&partnerID=40&md5=7ee5c5b0b144c7823927b1bf3f0a4bce id_number: 10.1016/j.oceaneng.2022.111151 full_text_status: none publication: Ocean Engineering volume: 252 refereed: TRUE issn: 00298018 citation: Kim, D.K. and Li, S. and Lee, J.R. and Poh, B.Y. and Benson, S. and Cho, N.-K.
