Assessment of in-Plane Behavior of Metal Compressed Members with Equivalent Geometrical Imperfection

Aguero Ramón Llin, Antonio; Balá , Ivan; Koleková, Yvona; Martín Concepcion, Pedro Efrén (MDPI AG, 2020-11-18)

[EN] A new procedure was presented with the objective of proving that it is the generalization of current attempts in designing compressed members and structures which is able to solve cases where other authors have problems. ...
Consistency of Imperfections in Steel Eurocodes

Balá , Ivan; Koleková, Yvona; Aguero Ramón Llin, Antonio; Balá ová, Pavla (MDPI AG, 2023-01)

[EN] The second-order theory was used to analyze the flexural buckling of an individual member simply supported on both member ends, with a uniform double symmetric cross-section under a uniform axial force in an elastic ...
Improved Interaction Formula for the Plastic Resistance of I- and H-Sections under a Combination of Bending Moments My,Ed, Mz,Ed, and Bimoment BEd

Aguero Ramón Llin, Antonio; Balaz, Ivan; Koleková, Yvona (MDPI AG, 2022-08)

[EN] The resistances of HVH sections (H-horizontal upper flange, V-vertical web, H-horizontal bottom flange) were investigated by the authors in the frame of the large parametrical studies focused on the complete HVH-section ...
INVESTIGATION OF METAL BUILT-UP COLUMNS PART I: FORMULAE

Balaz, Ivan; Koleková, Yvona; Moroczová, Lydia; Aguero Ramón Llin, Antonio (Akadémiai Kiadó, 2021-03-25)

[EN] Eurocodes give guidance how to design built-up columns having effective bending stiffness, smeared shear stiffness and local bow imperfection amplitude e0 = L/500 under compression. The guidance is valid only for ...
Investigation of metal built-up columns Part II: Results

Baláz, Ivan; Koleková, Yvona; Moroczová, Lydia; Aguero Ramón Llin, Antonio (Akadémiai Kiadó, 2021-06-03)

[EN] In the frame of a large parametrical study metal built-up columns made from steel and made of aluminum alloy were investigated. The second order theory is used for the analysis of the battened and laced built-up columns ...
New Interaction Formulae for Plastic Resistances of Z-Sections under Combinations of Bending Moments M-y,M-Ed, M-z,M-Ed and Bimoment B-Ed

Aguero Ramón Llin, Antonio; Baláz, Ivan; Koleková, Yvona; Lázaro, Mario (MDPI AG, 2023-07)

[EN] Exact interaction formulae for the plastic resistances of Z-sections under a combination of three internal forces, i.e., the bending moment about the strong axis (y,Ed), bending moment about the weak axis (z,Ed) and ...
