However, no parametric formulae on stress concentration factors (SCFs) of CFST K-joints have been established. In present study,\n three-dimensional FE models for determining the SCF distributions around the chord-brace intersections of CFST K-joints were developed first. The validity of the FE modelling has been examined by comparing \nwith the published experimental results. Then 272 FE models of CFST K-joints with different geometric dimensions were prepared and provided for the parametric study to demonstrate the influence of four key geometric parameters, i.e. diameter ratio (β), diameter to thickness ratio of chord (2γ), thickness ratio (τ) and the angle (θ) between the axis of the chord and brace, on SCFs around the chord-brace intersection. The analysis was performed under three loading conditions, i.e. the basic balanced axial forces, axial compressive force in the chord and in-plane bending in the chord. Finally, parametric formulae to determine the SCFs in CFST K-joints were proposed \nby the multiple regression analysis, and their accuracy was demonstrated through the comparison of SCFs obtained by the proposed formulae and FEA.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Engineering Structures, 190, pp.90-100; 2019","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Ltd."}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.engstruct.2019.04.017","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2019 Elsevier Ltd.
