Paper Number: ISOPE-I-95-290
... INTRODUCTION Tubular members are used commonly in space trusses and offshore structures. Such structures are highly redundant, and failure of an individual member does not necessarily lead to an overall structural collapse but merely causes Ii redistribution of forces among the members in the neighboring...
