摘要: The objective of this work is to analyze the fatigue reliability complex welded structures composed multiple web-frame joints, accounting for correlation effects. A three-dimensional finite element model using 20-node solid elements generated. linear elastic analysis was performed, hotspot stresses in a joint were analyzed and damage quantified employing S-N approach. statistical descriptors life non-correlated containing several critical hotspots estimated. wasmodeled as series system correlated components Ditlevsen bounds. entire structure with modeled parallel joints also calculated.
