Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Hot-Spot Stress Analyses of a T-Shaped Tubular Joint Subjected to Uniform, Grooving and Non-uniform Corrosion

“…The SCF deviation caused by non-uniform corrosion is statistically analysed. The crown toe along the intersection is divided into four regions: two crown regions and two saddle regions [11], as shown in Error! Reference source not found..…”

“…The SCF deviation for each weld toe node in the critical region where the maximum SCF appears is obtained as follows: SCF deviation caused by non-uniform corrosion is statistically analysed. The crown toe along the intersection is divided into four regions: two crown regions and two saddle regions [11], as shown in Figure 1. The SCF deviation for each weld toe node in the critical region where the maximum SCF appears is obtained as follows:…”

“…The Efthymiou equations are widely adopted in practice and incorporated into design codes [8]. Reviews on the SCFs of tubular joints can be found in [10][11][12].…”

Study on In-Plane Initial Rotational Stiffness of Eccentric RHS Beam-Column Joints

“…When calculating the effect of the stiffener on the rotational stiffness, the contribution of the stiffener was ignored if the calculated ΔK0 was negative. The effect of the stiffener on the joint rotational stiffness was calculated using Formula (11), while the initial rotational stiffness of the joint without a stiffener was calculated using Formula (8). These two values were then added together to obtain the initial rotational stiffness of the The parametric analysis results of the geometric parameters influencing the joint dimensions are presented in Figure 6.…”

“…However, RHS joints exhibit an uneven stiffness distribution within the cross-sectional area, leading to more complex stress distribution at the joint connection. As a result, scholars have conducted numerous studies on the static performance of various types of RHS joints, yielding a wealth of research findings [ 9 , 10 , 11 , 12 ]. The research outcomes on intersecting joints have been incorporated into relevant design specifications [ 13 , 14 , 15 , 16 ].…”
