“…The connection moment-rotation (M-φ r ) curves for different uniform temperature distribution across the joint are presented in Fig. 6(a), where one can observe good agreement between the experimental results (Al-Jabri et al, 2005) and the presented component model approach, previously given by Eq. (17).…”

“…The reinforcement bars in the slab are not considered in the beam design. The following S275 steel mechanical properties are considered in the analysis: f y,20 = 322 MPa and E = 197 kN/mm2 for 20ºC, as experimentally measured by Al-Jabri et al (2005). A standard firedesign curve (EC1-1.2, 2001) is postulated to occur at the first floor, between columns 2 and 3, as also indicated in Fig.…”

“…(17), to represent Ramberg-Osgood (1943) moment-rotation relationship for the proposed end-plate connection under fire conditions, are summarized in Table 2. The proposed values for the connection shape parameter n r were obtained by curve-fitting the proposed Ramberg-Osgood approach with experimental results from Al-Jabri et al (2005). …”

“…In this regard, the original Advanced Analysis Concept (e.g., Chen et al, 1996) has been extended to study the global performance of steel framed structures subjected to compartment fires (Liew et al, 1998(Liew et al, , 2002. Conversely, while a significant influence of connections on the behavior of framed buildings have been observed in real fires (Al-Jabri et al, 2005), and recently experimental programme (Yang et al, 2009, Daryan andYahyai, 2009), the performed numerical simulation of the join region -already complex at room temperature -becomes further complicated under fire (Simões et al, 2001;Wang et al, 2008;Mao et al, 2010;Chung et al, 2010). This paper is addressed to the development of an inelastic hingebased numerical tool, denoted as SAAFE Program (System for Advanced Analysis for Fire Engineering), able to perform material and geometric non-linearity analysis of 2D semi-rigid steel-concrete composite framed structures under fire conditions.…”

“…Obtained results of a proposed framed structure with different beamto-column support conditions are investigated by the SAAFE approach in section 3, in order to illustrate the efficacy of the proposed procedure for solving more complex structures under fire. In this section, results for a bolted end-plate connection are proposed and compared to experimental results (Al-Jabri et al, 2005) …”

10.11: Fire design of rectangular hollow section joints

et al. 2017

View full text Add to dashboard Cite

The component method is a design approach for the characterization of the mechanical properties of structural joints and it is referred to in Eurocode 3 Part 1-8. Eurocode design rules for open sections are already based on the component method. The design rules for joints between tubular hollow sections are still based on simple theoretical mechanical models validated against experimental test results. However, there are research activities in progress to extend the application of the component method also to hollow section joints in the next revision of Eurocode. The fire design of steel joints is carried out in accordance with Eurocode 3 Part 2. Eurocode gives only a guidance on how the temperature of the joint components can be assessed based on the local values of thermal resistance of the joint's fire protection. The method is not sufficient for the component method and Tampere University of Technology is currently carrying out experimental fire research to better understand the temperature distributions in the vicinity of the joint. The aim of the research is to develop experimental methods to determine steel temperatures at the actual joint component, spring, locations and to transfer this information into the joint design approach based on the component method. This paper introduces an experimental research demonstrating the actual temperature distributions within the joint area and highlights the differences between the failure modes and the design criteria at normal temperature design and fire design of a joint.
