Title: Nonlinear dynamics induced in a structure by seismic and environmental loading

Abstract

In this study,we show that under very weak dynamic and quasi-static deformation, that is orders of magnitude below the yield deformation of the equivalent stress strain curve (around 10^-3), the elastic parameters of a civil engineering structure (resonance frequency and damping) exhibit nonlinear softening and recovery. These observations bridge the gap between laboratory and seismic scales where elastic nonlinear behavior has been previously observed. Under weak seismic or atmospheric loading, modal frequencies are modified by around 1% and damping by more than 100% for strain levels between 10^-7 and 10^-4. These observations support the concept of universal behavior of nonlinear elastic behavior in diverse systems, including granular materials and damaged solids that scale from millimeter dimensions to the scale of structures to fault dimensions in the Earth.

Nonlinear softening of unconsolidated granular earth materials

Journal Article Lieou, Charles Ka Cheong ; Daub, Eric G. ; Guyer, Robert A. ; ... - Journal of Geophysical Research. Solid Earth

Unconsolidated granular earth materials exhibit softening behavior due to external perturbations such as seismic waves, namely, the wave speed and elastic modulus decrease upon increasing the strain amplitude above dynamics strains of about 10^-6 under near-surface conditions. In this letter, we describe a theoretical model for such behavior. The model is based on the idea that shear transformation zones—clusters of grains that are loose and susceptible to contact changes, particle displacement, and rearrangement—are responsible for plastic deformation and softening of the material. We apply the theory to experiments on simulated fault gouge composed of glass beads and demonstrate that themore »« less

Nonlinear dynamical triggering of slow slip

Conference Johnson, Paul A ; Knuth, Matthew W ; Kaproth, Bryan M ; ...

Among the most fascinating, recent discoveries in seismology have been the phenomena of triggered slip, including triggered earthquakes and triggered-tremor, as well as triggered slow, silent-slip during which no seismic energy is radiated. Because fault nucleation depths cannot be probed directly, the physical regimes in which these phenomena occur are poorly understood. Thus determining physical properties that control diverse types of triggered fault sliding and what frictional constitutive laws govern triggered faulting variability is challenging. We are characterizing the physical controls of triggered faulting with the goal of developing constitutive relations by conducting laboratory and numerical modeling experiments in shearedmore »« less

Seismic tests on models of reinforced-concrete Category I buildings

Conference Dove, R C ; Endebrock, E G ; Dunwoody, W E ; ...

The behavior of reinforced concrete (R/C), Category I noncontainment nuclear power plant structures subjected to seismic events of magnitude greater than used in their original design has been investigated using two sizes of scale models. Test results were analyzed to determine (1) maximum input for the response to remain linear/elastic; (2) changes in stiffness, damping, and modal frequency that are produced by seismic input greater than that causing linear elastic response; (3) changes in floor response spectra when the structure's response is nonlinear/inelastic; and (4) the magnitude of the seismic event necessary to fail (excessively crack) these structures.

Response of a base-isolated large liquid metal reactor plant to seismic loads

Conference Chang, Y W ; Gvildys, J

In recent years, base isolation has been applied to various civil structures such as bridges and buildings for the purpose of reducing its acceleration to below the level of ground accelerations during seismic events. The basic principal of base isolation is to introduce a soft layer of material between structure foundation to allow a degree of flexibility in horizontal motions which could reduce the seismic accelerations during earthquakes. If base isolation is properly designed, it shifts the fundamental frequency of the structure away from the damaging frequency range of earthquakes. Thus, the seismic loads transmitted to the structure can bemore »« less

Nonlinear viscoelastic behavior of sedimentary rocks. Part 1: Effect of frequency and strain amplitude

Journal Article Tutuncu, A N ; Podio, A L ; Gregory, A R ; ... - Geophysics

Sedimentary rocks display nonlinear elastic behavior. This nonlinearity is a strong function of frequency, strain amplitude, and the properties of the saturating fluid. Experimental observations and potential mechanisms that cause these nonlinearities are presented in this and a companion paper. Young`s modulus and Poisson`s ratios obtained from ultrasonic laboratory measurements (50 kHz, 100 kHz, 180 kHz and 1 MHz), low-frequency measurements (1--2,000 Hz) and static measurements (0.001--0.05 Hz) show significant differences under identical stress conditions. A comparison of the laboratory-measured quantities with log-derived moduli measured at 20 kHz indicates that E{sub ultrasonic} > E{sub log} > e{sub lowfreq} > E{submore »« less
