In the United States, state-of-practice methods for approximating seismic shear in special moment frames (SMRFs) may underestimate the magnitude forces that SMRF columns [...]

The building structures are generally irregular and regularity is only an idealization that rarely occurs. Structural irregularity may be classified as in- plan and in-el [...]

Prior 2010, out-of-plane instability in slender boundary elements subjected to cyclic loading had been observed in some experimental tests conducted on columns and walls [...]

The life safety risk from seismic vulnerabilities of older concrete buildings, particularly frame buildings, is well known. Existing evaluation methods – which are base [...]

Earthquake reconnaissance has reported the substantial damage that can result from inadequate beam-column joints in earthquake shaking. In some cases, failure of oldertyp [...]

In order to observe the interaction of structural elements at the onset of collapse, four frame specimens are planned to be tested at the National Center for Research on [...]

Several west coast cities are seeing an upsurge in the construction of high-rise buildings. Many of these buildings feature framing systems, materials, heights, and dynam [...]

Post earthquake reconnaissance studies show that the primary cause of collapse in older non-seismically detailed reinforced concrete buildings is the loss of vertical-loa [...]

In areas of high seismicity around the world, the collapse vulnerability of older RC structures built prior to the advent of more effective seismic design codes is under [...]
