Performances and damages to steel structures during the 1995 Hyogoken-Nanbu earthquake

Refined Analysis of Fatigue Crack Initiation Life of Beam-to-Column Welded Connections of Steel Frame under Strong Earthquake

“…Seismic damage investigations after the Northridge and Kobe earthquakes show that fatigue crack initiation and propagation at or near the welded connections may cause serious seismic damage, which can endanger the safety of steel frame structures and even cause the collapse of steel frame structures [1,2]. The typical fracture of beam-tocolumn welded connections caused by earthquakes is shown in Figure 1.…”

Finite Element Analyses on Free From Damage Seismic Resisting Beam-to-Column Joints

“…Although effective and economically advantageous at the construction stage, the capacity design philosophy applied to traditional structural systems requires structural damages after seismic events, thus leading to significant economic losses [9][10][11][12][13].…”

Seismic response of stainless steel braced frames

“…The variability of yield f y and/or ultimate f u stress and elongation at fractures ε u may lead to unforeseen failure modes, undermining hysteretic response and expected global structural performance (e.g. [21,15]; among many others). Typical brittle fractures and failure modes caused by fatigue at beam-tocolumn in steel moment resisting frames and in brace-tocolumn connections in braced frames are shown, for example, in Fig.…”
