Effect of Column-to-Beam Strength Ratio on Seismic Performance of RC Moment Frames
Reinforced concrete (RC) moment frames are often used in building applications. During strong earthquake excitations, such buildings have been subject to soft-story or column sidesway...
The Effect of the Slab on Beam-Column Joint Behavior
The three-dimensional effect of slab interaction on frame behavior has been observed in lateral load tests on beam-column-slab elements....
New Concepts in Structural Strength Assessment for Large Buildings in Fire
