“…Bucmys and Sauciuvenas [13] mentioned that design standard; Eurocode 3-1-3 did not propose brief information and calculation of the moment-rotation of connections or their relationship but only established strength calculations. Baur and Suaris [6] reported the AISI standard only explained about testing prediction data and the relationship but did not touchabout the method of testing in detail.…”

Cold-formed steel (CFS) is a popular steel-based material for building such as roof truss system and wall frame panel. CFS with a variety of shapes, cross-sections and thickness produce a lot of advantages such as ease of production, corrosion resistance and high strength to weight ratio. Connection of the CFS sections between them uses screw, bolt and nut, rivet or weld. But, the detail information for the connector in standard either by Eurocode 3 or American Iron and Steel Institute (AISI) is still incomplete especially methods for testing and also lack in the basic knowledge of testing for the connector or combination of connectors. The connector that was used in this study was a self-drilling screw. The objective of the study is to provide the mechanical behaviour information of self-drilling screws from shear and pull-out tests. Both tests utilised Universal Testing Machine with 100 kN capacity to determine the ultimate load and load-deformation behaviour of the self-drilling screws with different numbers. As a result, the ultimate load of the specimen was found to increase with increasing number of the self-drilling screws for shear and pull-out connection tests.

“…In the same article, a semi-empirical design method for calculating rotation stiffness of gusset plate connections was presented. In Bucmys and Sauciuvenas's paper [19] simulation data of the behaviour of beam to-column connections with Tform gusset plates has been presented. The authors examined the behaviour of gusset plate connections and took into account a variety of thicknesses and the geometrical structure of the gusset plate.…”

Cold-formed structure connections utilizing gusset plates are usually semi-rigid. This paper investigates the behaviours of rectangular gusset plates in cold-formed connections of elements whose columns and beams are made with lipped back-to-back C-sections. Methods of calculating strength and stiffness are necessary for such semi-rigid joints. The main task of this paper is to determine a method capable of calculating these characteristics. The proposed analytical method could then be easily adapted to the component method that is described in part 1993-1-8 of the Eurocode. This method allows us to calculate both the strength and stiffness of rectangular gusset plates, assuming that the joint deforms only in plane. This method of design moment resistance calculation was presented taking into account that an entire cross-section shall reach its yield stress.A technique of stiffness calculation was presented investigating the sum of deformations acquired at the bending moment and from shear forces which are transmitted from each beam bolt group.Calculation results according to the suggested method show good agreement of laboratory experimental results of specimens with numerical simulations. Two specimens of beam-to-column connections were tested in the laboratory. Lateral supports were used on the specimens to prevent lateral displacements in order to better investigate the behaviour of the rectangular gusset plate in plane. Experiments were simulated by modelling rectangular gusset plates using standard finite element software ANSYS Workbench 14.0. Three-dimensional solid elements were used for modelling and both geometric and material nonlinear analysis was performed.

“…Bučmys et al (2014) investigated the influence of lateral restraints on the stiffness and strength of the joint. In the paper by Bučmys and Šaučiuvėnas (2013), the simulation data of the behaviour of beam-to-column joints with a gusset plate was presented. The authors examined the behaviour of the joint with a gusset plate to take into account the variety of thicknesses and the geometry of the gusset plate.…”

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
