Performance Assessment of Seismic Resistant Steel Structures
… motions should cautiously be used for near-field structures. The effects of nonlinear accidental torsion are also examined in detail and are determined to have a significant effect on the inelastic behavior of the analyzed structure. The final investigation in this study shows that even if a …

The Grillage Analysis of Multi-Cell Steel Structures
… grillage method for predicting the behaviour of steel multi-cell structures. Simply supported, straight and skew structures will be considered subjected to a variety of loading conditions. The proposed analysis can be achieved using a low cost micro-computer, and it is considered that the method …

Analysis and comparison of connections in steel structures
… members, but leave the connection details to the steel fabricator. While this practice is more efficient and pragmatic in some instances, it is also necessary for structural engineers to have a good knowledge of connection behavior, especially when dealing with newer or atypical connections. Both …

Applicability of undermatched welds for high strentgh steel structures
… strength of welded joints, made on high strength steels with different degrees of strength matching. The steels involved are the HY-100 and HY-130 U.S. Navy, quenched and tempered steels. The test methods are the self restraint cracking test, the tensile test and the fatigue test. The investigated …

Pattern recognition techniques applied to rust classification in steel structures
The life and performance of steel structure depends directly upon the steel surface preparation. The restoration of steel structure such as steel bridges, ships and storage tanks is due mainly to the use of manual surface inspection methods accompanied by surface preparation technologies. It …

Implementation of linear analysis in the early stages of performance-based design for steel structures
In the aftermath of the destructive 1994 Northridge Earthquake in Southern California, the earthquake engineering industry experienced a shift towards expanding seismic requirements beyond surviving global collapse to include performance criteria. As a part of this effort, the Pacific Earthquake …

Development and Characterization of a Self-Stressing Shape Memory Alloy (SMA)-Fiber Reinforced Polymers (FRP) Composite Patch for Repair of Cracked Steel Structures
… to traditional methods to repair cracked steel structures and civil infrastructure. However, existing prestressing methods require the use of heavy and complex fixtures to apply prestressing forces, which is impractical in many applications. In this research a self-stressing shape memory …

Three-Dimensional Finite Element Analysis of Stiffened Tee-Hangers.
All framed steel structures require moment-resistant connections to join the various members. These connections form a more rigid structure using less steel by distributing the moments throughout the structure. However, the moment-resistant connection geometry combines with the support conditions …
