“…The strain hardening slope is a function of fy, fu and εy, which are all readily available to a designer, as well as εu, which is not typically available to a designer, but may be predicted using Eq. (10). Detailed information on the derivation of these material coefficients is given by [34,36] for cold-formed steels, [5,35,37] for stainless steels, and [9,38] for aluminium alloys.…”

“…Later, further developments highlighted the breadth of applicability of the method and its true potential as a system-level design approach. The CSM has now been applied to the design of steel [3,4], stainless steel [5][6][7][8], aluminium alloy [9,10], reinforced concrete [11] and composite structures [12,13], as well as steel structures in fire [14,15]. Recent attention has been focussed upon extension of the CSM to member-level design [16][17][18][19] and incorporation of the CSM into a framework of design by advanced analysis [20][21][22][23] and into codes of practice; the CSM now features in the AISC Design Guide for Structural Stainless Steel (2013), the fourth edition of the SCI Design Manual for Structural Stainless Steel (2017), the draft prEN 1993-1-4 for the design of stainless steel structures, the draft prEN 1993-1-14 for the design of steel structures by finite element analysis, the ASCE Specification ASCE-8-21 for the design of cold-formed stainless steel structures and the AISC Specification AISC 370 for the design of hot-rolled and welded stainless steel structures.…”

The Continuous Strength Method – Review and Outlook

2022

View full text Add to dashboard Cite

The Continuous Strength Method (CSM) is a deformation-based approach to the design of structures that enables a continuous, rational and accurate allowance for material nonlinearity. Central to the method is the application of strain limits to define the resistance of a structural member or system.The method can be applied to structures formed using different materials and manufacturing processes and can be used for steel-concrete composite design and in fire scenarios. The design method enables enhancements in structural efficiency and, unlike traditional approaches, allows the assessment of both strength and ductility demands (particularly relevant for high strength steel) at the ultimate limit state. For hand calculations, a set of straightforward CSM design equations have been developed. Recognising the increasing importance and use of advanced analysis, recent research, summarised herein, has focused on integration of the CSM strain limits into a framework of design by second order inelastic analysis, where the benefits of the method become even more substantial. This paper provides a review of the background and recent developments, including incorporation into design standards.

“…In 2019, Wang et al [96] carried out 30 tests of extruded aluminium T-stubs specimens connected by swage-locking pins under monotonic loads. The different specimens were designed by varying the distance between the pins and the web (m + 0.8r), the flange thickness, the swage-locking pin collar type and the diameter and layout of the fasteners.…”

A Review of the T-Stub Components for the Analysis of Bolted Moment Joints

et al. 2021

View full text Add to dashboard Cite

The analytical method for the calculation of the properties of a bolted joint established by the structural Eurocodes proposes the T-stub as a component for the characterization of the tension and compression zones in moment joints. In this article, a review of the state of the art on the T-stub component is developed, where the works developed since it was initially defined, and from the perspectives of formulation, experimentation and numerical simulation are summarized and discussed. Additionally, possible future lines of work are proposed.

“…To date, the research data on aluminium beam-to-column joints are scarce. Most of the research is related to joint components with mechanical fasteners, i.e., T-stubs [14][15][16][17][18][19][20][21][22]. In recent years, research has started on bolted beam-to-column joints in full-scale [23,24] to characterise their behaviour, and thus the behaviour of aluminium frame systems.…”

Parametric Numerical Study of Welded Aluminium Beam-to-Column Joints

2023

Beam-to-column joints are one of the most common types of joints in metal structures. In the design of load-bearing aluminium structures, welding, as a joining method, is often avoided because of localised degradation of mechanical properties in the heat-affected zone (HAZ). However, recent experimental studies on the extent and strength of the HAZ show a significant difference compared to very conservative design rules when modern welding techniques are used. Therefore, the numerical study conducted in this paper addresses the influence of HAZ on the mechanical behaviour of the welded aluminium beam-to-column joint. Parametric numerical analyses were performed varying the aluminium alloys, the reduced mechanical properties of the HAZ, and different definitions of the HAZ extent. The obtained results show that the highest stress concentration occurs at the connection between the top beam flange and the column flange, resulting in plastic softening in this region. Different joint capacities were observed by varying the mechanical properties of the HAZ. A detailed overview of numerical models as well as the obtained moment–rotation curves show that the behaviour of some models is not as conservative as assumed in the design standards considered.
