The corrosion of steel reinforcement in an aging highway infrastructure is a major problem currently facing the transportation engineering community, in particular bridge engineers. In the United States, maintenance and replacement costs are measured in billions of dollars. Further, the use of deicing salts has resulted in steady deterioration of bridge decks due to corrosion. These concerns ha...

Abstract This paper summarizes the experimental campaign carried out for development of a new steel energy dissipative devices named Slit Dampers (SDs) designed earthquake protection structures. SDs consist in shear plates with appropriately shaped cut‐out portions material allowing maximum spread plastic deformation along device and then maximizing hysteretic behavior. A total eighty‐two diffe...

This investigation compared four conventional vehicle armour materials for performance under blast loading. The parameters measured were resistance to deformation, mechanical toughness and metallurgical microstructure. It was found that two of these, the M steel and A steel, showed the least deformation and M steel showed better shock energy absorption. B steel had high toughness but showed sig...

Background: When a severe earthquake ground motion hits the structure even if it doesn’t collapse may undergoes inelastic deformations. Steel infilled with precast panels becomes less efficient when subjected to large lateral loads like strong wind and earthquake. Hence assessment of actual performance steel frames provided infills in event is essential. Methods: In current study, prototype mod...

Abstract This paper intends to provide quantitative seismic response characteristics of steel moment resisting frames (MRFs) with inelastic beam‐to‐column panel zone joints. Two modeling approaches are proposed for this purpose along a methodology consider the fracture potential at bottom beam flange in MRFs due kinking. Both approaches, which validated available experiments, preserve behaviora...
