Abstract: Space trusses of the double‐layer grid type, because of their large degree of static indeterminacy, are often assumed to have sufficient redundancy such that the loss of one member would cause force redistributions that ...

Abstract: Nonlinear methods of analysis for space trusses are reviewed. Methods which do not require repeated reformation and reinversion of the stiffness matrix appear to give the greatest computational efficiency. A new method of ...

Abstract: An analogy between the bending of simply supported plates loaded by uniformly distributed edge moments and the torsion of prismatic bars is derived. The analogy is drawn for both straight‐sided and circularly curved ...

Abstract: The computational models used for compression members in the nonlinear analysis of space trusses are classified by decreasing order of computational effort into finite‐segment, finite‐difference, and single‐member solutions. ...

Abstract: Systems for torsional stiffening, including longitudinal plate, transverse plate, box, and cross stiffeners of I-beams are reviewed. Different configurations for cross stiffeners are presented, including crosses fully ...

Abstract: Progressive collapse was defined as “the widespread propagation of failure following damage to a relatively small portion of the structure,” by Breen in 1975. Existing quantitative approaches to prevent progressive collapse ...

Abstract: Cold‐formed steel channel struts are structural elements often used in the fabrication of double‐layer grid‐space frames. Fabrication and assembly considerations sometimes require joint configurations that cause members ...

Abstract: Equal‐leg angle cruciform members are known to be prone to torsional buckling. The primary parameters controlling torsional buckling mode are the width/thickness ratio of the outstanding legs, and the degree of warping ...
