Abstract: A two-story waffle–flat-plate reinforced-concrete model structure was subjected to cyclic loading simulating a severe earthquake. The test structure was a one-third-scale model that represented a structural system that is ...

Abstract: A seismic damage index is validated using data from shaking table tests on full-scale and scaled reinforced concrete (RC) specimens. The experimental specimens include wall and frame lateral building systems and ductile ...

Abstract: Stiffness modifiers are used in linear structural analysis programs to recognize the low-strain amplitude nonlinear material stress–strain response and support the design of reinforced concrete structures. For example, ...

Abstract: Floor accelerations are needed to evaluate in-plane diaphragm forces in earthquake resistant design of buildings, and for the design of their connections. Recorded floor accelerations in buildings during some past earthquakes ...

Abstract: It is expected that during strong earthquakes, longitudinal reinforcing steel in reinforced concrete structural elements may undergo large tension and compression strain reversals. Because of insufficient tie spacing, this ...

Abstract: In this paper a complete characterization of lime cycle transitions is described.
