To study the effect of collar-plate reinforcement on the static strength of tubular T-joints under axial loading, fundamental research work is carried out from both experimental test and finite element (FE) simulation. Through experimental tests on 7 collar-plate reinforced and 7 corresponding un-reinforced tubular T-joints under axial loading, the reinforcing efficiency is investigated. Thereafter, the static strengths of the above 14 models are analyzed by using FE method, and it is found that the numerical results agree reasonably well with the experimental data to prove the accuracy of the presented FE model. Additionally, a parametric study is conducted to analyze the effect of some geometrical parameters, i.e., the brace-to-chord diameter ratio <i>β</i>, the chord diameter-to-chord wall thickness ratio 2<i>γ</i>, collar-plate thickness to chord wall thickness ratio <i>τ</i><sub>c</sub>, and collar-plate length to brace diameter ratio <i>l<sub>c</sub></i>/<i>d</i>1, on the static strength of a tubular T-joint. The parametric study shows that the static strength can be greatly improved by increasing the collar-plate thickness to chord wall thickness ratio <i>τ</i><sub>c</sub> and the collar-plate length to brace diameter ratio <i>l<sub>c</sub></i>/<i>d</i>1. Based on the numerical results, parametric equations are obtained from curving fitting technique to estimate the static strength of a tubular T-joint with collar-plate reinforcement under axial loading, and the accuracy of these equations is also evaluated from error analysis.
