GMNIA-Based Evaluation of Cable-Prestressed H-Shaped Steel Columns
Applied Sciences (Switzerland)The strengthening technique by external cable prestressing, until now limited to columns with circular hollow sections (CHSs), is here extended to H-shaped steel columns. To provide an innovative general treatment, an initial imperfection, obtained from

Design of stainless steel structural systems by GMNIA with strain limits
Engineering Structures, 2023 Design by GMNIA (Geometrically and Materially Nonlinear Analysis with Imperfections) allows the key behavioural features of structures to be directly captured in the analysis, improving accuracy and dramatically reducing the need for subsequent design checks. Since the analysis of frames typically employs beam elements, in which local buckling of cross-

Experimental and numerical datasets for benchmark tests on high strength steel I-section frames [PDF]
Data in BriefThis data article presents experimental and numerical datasets for eight fixed-base, single storey, unbraced high strength steel welded I-section frames subjected to in-plane horizontal and vertical loading. A detailed description of the full-scale frame

Towards a practicable GMNIA procedure in the footsteps of the Direct Design Method
Ce/Papers, 2023 AbstractEurocode 3 permits to utilize nonlinear finite element analysis (NFEA) in design process by carrying out Geometrically and Materially Nonlinear Analysis with Imperfections (GMNIA). Design by GMNIA can consider material plasticity and redistribution of forces in a system level such that it can result in an economical design regarding the ...

Equivalent global sway imperfections for use in design by GMNIA
Ce/Papers, 2023 AbstractThree types of geometric imperfection need to be considered in the design of structural systems: global frame out‐of‐plumbness, also referred to as sway imperfections, member out‐of‐straightness, also known as bow imperfections, and local cross‐section imperfections.

GMNIA‐based design of stainless steel structural systems
Ce/Papers, 2023 AbstractDesign by GMNIA (Geometrically and Materially Nonlinear Analysis with Imperfections) allows the key behavioural features of structures to be directly captured in the analysis, dramatically reducing the need for subsequent design checks. Since the analysis of frames typically employs beam finite elements, which do not explicitly account for ...

Out‐of‐plane Stability Design by GMNIA – Equivalent Imperfections and Strain Limits
Ce/Papers, 2022 AbstractAn accurate and consistent approach to the out‐of‐plane stability design of steel beams and structures utilising geometrically and materially nonlinear analysis with imperfections (GMNIA) and strain limits is proposed. The method is implemented using computationally efficient beam elements, with the ultimate structural resistance defined either

Ce/Papers, 2022 AbstractThe flexural buckling resistance of compressed columns is typically determined using the flexural buckling curves of EN1993‐1‐1. With advances in computing capabilities, it has become possible to obtain the flexural buckling resistance as a result of a geometrically and materially nonlinear analysis (GMNIA) using imperfections.
