The goal of the National Center for Earthquake Engineering Research (NCEER) is to coordinate a team effort in the study of earthquake engineering which will substantially enhance the state-of-the-art. Current activities ...

The second-year research plan of the National Center for Earthquake Engineering Research (NCEER) is presented. NCEER's six basic research programs are chiefly described. These are the programs on: 1) Existing structures, ...

In a continuing effort to determine the feasibility of applying optimal control to building structures, a comprehensive experimental study was carried out using a standardized structural model under base excitation supplied ...

A study of the dynamic impedances for a radially inhomogeneous infinite viscoelastic layer with a circular hole, and for piles embedded in a medium represented by such layers is made. Systems in vertical and torsional modes ...

A study of the dynamic impedances of thin, infinite viscoelastic soil layers with a circular hole is made considering a continuous, ramp-like variation for the shear modulus of the material. Both vertically and torsionally ...

The method of spectral representation for uni-variate, one-dimensional, stationary stochastic processes and multi-dimensional, uni-variate (as well as multi-dimensional, multi-variate) homogeneous stochastic fields has ...

This report describes the plans for a computer modeling and analysis system for transient fully nonlinear seismic analysis of large buildings. The emphasis is on modeling the buildings at a "macro" level, i.e., ...

The problem of earthquake damage assessment is defined. The role of the analysis of strong motion records in damage assessment codes based on expert system is pointed out. A literature survey on damage assessment and ...

The objective of this paper is to provide a state-of-the-art assessment of active control research as applied to civil engineering structures. An attempt is made to present it with less specialized research content suitable ...

The chances of a major earthquake occurring in New York State in the near future is low. However, historically New York State has experienced and no doubt will continue to experience moderate earthquakes with a maximum ...
