Abstract
Structural design is nowadays still made on a member-by-member basis. But the reliability of redundant or hyperstatic systems is known to be larger than that of isostatic or non-redundant systems. This paper makes an objective investigation on the optimal design of redundant systems. The study is based on different proportioning for the active and passive parts of structural redundancy, and brittle and ductile materials, strength correlation, progressive collapse and impact factors in load redistribution. The differentiation of consequences of failures, which occur in a direct or progressive manner, is a significant aspect of the study.
