“…When determining the value of F tr,Rd for the bolt row r the effective design tension resistance of all other bolt rows closer to the centre of compression should be ignored [10]. The following indices are used in Figure 4: (a) -design tension resistance of the 1 st bolt row, farthest from the centre of compression, analysed as a separate bolt row; (b) -design tension resistance of the 2 nd bolt-row analysed as a separate bolt-row; (a+b) -design tension resistance of the 1 st and 2 nd bolt rows, where these bolt-rows are analysed as a part of the bolt group.…”

“…The component method ranks among the methods that are most commonly used for determining the moment resistance and rotational stiffness of joints. This method is implemented in the European steel design code [9], which is widely used for the steel beam-to-beam or beam-to-column joints [10,11]. No methods are currently provided in European timber structure design codes that can explain how to apply the component method for determining the moment resistance of combined timber -steel joints.…”

Use of component method in the analysis of timber-steel connectionsThe use of component method for determining the moment resistance of an innovative beam-to-beam timber-steel connection is presented in the paper. The calculation of resistance of steel components is conducted based on EN 1993-1-8. The resistance of timber components is determined according to EN 1995-1-1, and based on the fullscale laboratory experiments and the finite element modelling results. The developed moment resistance calculation model, based on the component method, is well in line with the full-scale experimental and finite element modelling results. Primjena metode komponenata u proračunu drveno-čeličnog priključka U radu je predstavljena metoda komponenata za određivanje otpornosti na savijanje u inovativnom drveno-čeličnom priključku greda-greda. Proračun otpornosti čeličnih elemenata priključka proveden je u skladu s normama EN 1993-1-8. Otpornosti pojedinih drvenih elemenata određene su prema normi EN 1995-1-1, a temelje se na laboratorijskim ispitivanjima uzoraka stvarne veličine i rezultatima modeliranja konačnim elementima. Razvijeni model proračuna otpornosti na savijanje, prema metodi komponenata, dobro se podudara s rezultatima ispitivanja uzoraka stvarne veličine i modeliranja konačnim elementima.

“…To show the effect of semi-rigid joints on the behaviour of whole framed structures, the analysis of behaviour of a portal frame (Daniūnas and Urbonas 2008) and roofing structure (Urbonas and Daniūnas 2006) are presented. The joint characteristics under simultaneous action of bending and axial forces are obtained and analysis of framed structures is performed according to the above mentioned methods.…”

Abstract. This research work describes the analysis of steel semi rigid joints that are subjected to bending and tension or compression. The main attention is focussed on the beam-to-beam and plate bolted joints. Usually influence of axial force is neglected. In fact, the level of tension or compression of axial force can be significant and has some impact on joint behaviour and on its stiffness and strength characteristics. Nowadays the most powerful method for the estimation of joints characteristics is the component method. The adaptation of the component method for the determination of joints characteristics under bending ant axial forces is shown in the paper. Some numerical results of calculations of steel frameworks are presented in this paper as well (Daniūnas and Urbonas 2008).

“…In the last few decades, the concept of semi-rigid joints became more popular. The researches of steel frames with semi-rigid joints showed that the stiffness of joints had a significant influence on the behaviour of frame elements (Del Savio et al 2009;Díaz et al 2011;Daniūnas, Urbonas 2008. The real behaviour of the framework allows designing safer structures and reaching the economic benefit (Daniūnas, Urbonas 2013;Ćirović et al 2014;Fayyadh, Razak 2014;Kala 2015;Misiūnaitė et al 2012;Talaslioglu 2015).…”

abstract. Nowadays, cold-formed constructions are being used more frequently on construction sites because of the good strength-to-cost ratio. However, insufficient studies are published examining the properties of these constructions. This paper investigates the behaviour of bolted gusset-plate joint since it is one of the easiest ways to connect a beam to a column. The paper presents analytical calculations using the component method and experimental test results. The joint was investigated using the mechanical model of three springs. The mechanical model for the calculation of bolt group stiffness was created according to Eurocode 3 Part 1-8 Stiffness formulations (EN 1993(EN -1-8 2005 (originally, it is recommended for elements that are 4 mm and thicker). The technique for the calculation of the stiffness of a gusset plate is presented. The strength of the joint was calculated using the technique introduced in
