چکیده مقاله
In the present paper, the Local Joint Flexibility LJF of the tubular X joints reinforced with external plates under compressive load is investigated In the first phase, a finite element FE model was generated and verified with the results of experimental tests and available equations In the next phase, a set number of 117 FE models were created to evaluate the role of the external plate size βp and p , and the connection geometry y, , and β on the LJF factor fLJF In these FE models, the weld connecting the chord and brace members was generated The results indicated that the growth of the plate size βp and p , β and , and the decrease of the y led to the decrease of the fLJF Despite the notable effect of the external plate on the fLJF, there is no study or formula on tubular connections reinforced with external plates Therefore, the FE results were used to propose a parametric formula for determining the fLJF in X joints with external plates under brace compressive load Moreover, the derived formulas were checked based on the UK DoE acceptance criteria
