Abstract: In dynamic analysis, the energy dissipation in a base-isolated building is typically accounted for by allocating damping properties independently to the superstructure and to the isolation system. Rayleigh damping applied ...

Abstract: An earlier procedure that estimates the peak deformation in base-isolated buildings is extended to include overturning and thereby estimate the peak axial forces in individual isolators. Such tools can be used as part of ...

Abstract: A full-scale earthquake simulation of a five-story steel moment frame building at E-Defense, the world’s largest single shake table facility in Miki, Japan, in August 2011 provided realistic data to improve and validate ...

Abstract: A procedure based on rigorous nonlinear analysis that estimates the deformation and force of an isolator due to strong ground motion is presented. The procedure offers an alternative to the iterative equivalent-linear ...

Abstract: This paper focuses on a horizontal-vertical coupling effect observed in a full-scale shake table experiment of a 5-story moment frame building isolated with triple pendulum bearings. A significant increase or amplification ...

Abstract: Although current code guidelines specify different seismic performance objectives for fixed-base and isolated buildings, the future of performance-based design will allow user-selected performance objectives, motivating ...

Abstract: Existing models for isolation bearings neglect certain aspects of their response behavior. For instance, rubber bearings have been observed to decrease in stiffness with increasing axial load, and soften in the vertical ...

Abstract: Temperature profiles for bridge design were developed and introduced into current bridge design specifications after soffit cracking in prestressed concrete bridges was attributed to nonlinear temperature distribution ...

Abstract: Chapter 17, “Seismic Design Requirements for Seismically Isolated Structures,” in the 2016 edition of the ASCE 7 Standard, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, includes major ...
