We use a.preconditioned conjuga.e gra.ient a.gorithm, a.plied to a. a.socia.ed opera.or equa.ion of elliptic type, to solve the problem. To solve the elliptic pa.tia. differentia. equa.ions, we use a.second order mixed finite element a.proxima.ion for discretiza.ion.

a. importa.t considera.ion when using hot-dip ga.va.ized tubula. structures is the uncerta.nty of the joint beha.iour due to the possible reduction in the globa. joint resista.ce produced by the vent holes required for the ga.va.izing process. This pa.er a.sesses the effect on the joint strength of the a.gle between the bra.e members a.d the chord in a.K- or N-joints ma.e with recta.gula. hollow sections. The study is focused on the ca.e when those bra.e members include cha.a.teristic holes required for the hot-dip ga.va.izing process. To a.complish the objective of the proposed work, some tests on full-sca.e K- a.d N-joints, including a.gles of 35°, 45°, 55° a.d 90°, were ca.ried out. The experimenta. work wa. complemented by a.va.ida.ed numerica. simula.ion in order to give some design recommenda.ions a.d to extend the resea.ch to other joint configura.ions.
