Abstract: Improved damage spectra are proposed to quantify the damage potential of recorded earthquake ground motion. The damage spectra are based on a combination of normalized hysteretic energy and deformation ductility of a series ...

Abstract: Results are summarized of analytical and experimental studies conducted on physical and analytical models of a 15‐story reinforced concrete framecoupled wall structure which was identified as typical of medium‐rise office ...

Abstract: Provisions of 1982 UBC, ACI 318‐83, and ATC 3‐06 pertaining to seismic shear design of slender walls in mid‐rise construction are evaluated. In the event of major ground shaking in regions of high seismic risk, the actual ...

Abstract: This paper discusses the widely accepted seismic design limit state philosophy and the serviceability limit state requirements for stress and drift controls in the 1988

Abstract: Many uncertainties are associated with the selection of the design earthquake for a particular structure. In an attempt to address such problems, a ten‐story steel frame is designed for the lateral force requirements in ...

Abstract: The states of the practice and art in seismic design of reinforced concrete dual frame‐wall structural systems are reviewed. The review leads to the need to emphasize the use of conceptual seismic design principles to ...

Abstract: The effects of redundancy on the probability of structural failure are analyzed, emphasizing relationships with the over-strength and ductility ratios. The introductory remarks make reference to the difficulties that exist ...

Abstract: A series of analytical studies on the hysteretic behavior of R/C interior beam‐column joints are presented. Parameters varied include the ratio of top to bottom reinforcement, the yield strength of reinforcing bars and the ...

Abstract: An accurate and efficient analytical model describing the hysteretic behavior of R/C beam‐column joints subjected to random cyclic excitations is presented. The model takes into account the cyclic bond deterioration along ...
