Review: Constrained finite strip method developments and applications in cold-formed steel design

General distortional buckling formulae for both fixed-ended and pinned-ended C-section columns

“…However, a sharp corners model, as shown in Fig. 4, was used to analyze distortional buckling by Lau and Hancock [15], Schafer [16,17] and Silvestre and Camotim [22][23][24] for simplified analysis because the corners have only a modest influence on the distortional buckling solutions [27,28]. Additionally, as stated in [29], the influence of rounded corners on the cross-sectional resistance may be neglected if the external radius r r6t (for an internal radius r5t).…”

“…The rounded corners are not included in Fig. 7 because the corners have only a modest influence on distortional buckling solutions [27,28]. Taking the same procedure as Lau and Hancock [15], the distortional formulae for fixed-ended columns under axial loads, will be obtained.…”

Buckling analysis of thin-walled members via semi-analytical finite strip transfer matrix method

“…Furthermore, the cFSM innovated from SAFSM is developed and applied in the determination and classification of buckling modes. 27 By extending the applicability of the cFSM to the domain of general finite element analysis, the buckling modal identification of the thin-walled member has been demonstrated. 28 The classical transfer matrix method (TMM) has been developed as an effective tool for structural analysis, especially for chain connected system from topological perspective.…”

Load carrying capacity of functionally graded columns with open cross-sections under static compression

“…These two alternative modal approaches to analyze the elastic buckling behavior have been compared in [29][30][31]. For the latest trends in the development of the GBT, see for example [32][33][34][35][36][37][38]. In these papers special attention is focused on an effect of global and local distortional modes on the load carrying capacity of structures.…”
