Three-dimensional, inelastic response of single-edge notch bend specimens subjected to impact loading
… of impact loads is sufficient to produce large inelastic deformations, the assessment of crack-tip conditions must include the effects of plasticity, strain rate and inertia. This research examines the interaction of impact loading, inelastic material deformation and crack geometry with the goal …

Behaviour and modelling of the inelastic response of concrete and steel-concrete infrastructures subjected to low-cycle fatigue
… to guarantee the safety of citizens, the seismic response of infrastructures under an earthquake requires a careful evaluation of the level of damage of structural elements. In this thesis, typical case studies are considered, such as a concrete tunnel lining and a composite steel-concrete bridge. …

Using Pulse R -Factors to Estimate Structural Response to Earthquake Ground Motions
"A new method is developed for estimating inelastic response to strong ground motions. The method applies strength reduction (R) factors determined for a simple pulse to the elastic spectrum of the ground motions to estimate inelastic response spectra. Optimal pulse shapes and durations are …

The permanent deformation of steel portal frames subjected to impulsive loading
The inelastic response of steel portal frames with a mass attached to the centre of the beam member and subjected to large dynamic loads is studied. The analysis is carried out using the mode approximation technique extended to include strain-rate sensitivity, finite deflections and pulse duration. …

The United States sheep industry: producer behavior and supply response
… expansion and elasticities indicate a relatively inelastic response by producer in the short-run. Subjective factors are found to be important determinants of flock size. The supply function of U.S. sheep inventories is hypothesized to operate under asset fixity in reverse. Implications for …

Estimation of tax rate elasticities of durable assets: utility maximizing approach using the AIDS model
… research originated on the premise that if the response of various tax bases to changes in tax rates is different, local governments can minimize stress on tax bases by placing differential levels of reliance on these tax bases. Therefore, the objective of this research was to estimate and …

A study of the maximum transient response of simple fully yielding structures
… of the characteristic features of the transient response of fully yielding structures to a dynamic exciting force. The study was concerned with an estimation of the maximum possible peak-to-peak amplitude of simple idealised models subjected to pulses of a sinusoidal nature. The study was mainly …

Response of ten story, reinforced concrete model frames to simulated earthquakes
… of this research was to study both elastic and inelastic response of reinforced concrete structures subjected to strong earthquake excitations. This was a part of continuing research supported by National Science Foundation, Grant ENV 7422962. In the experimental phase, test structures made up …

Comparison and convergence studies of nonlinear finite element beam-column models
… The models are tested over the entire range of response. The tests indicate that both models predict accurate responses throughout the range of response. Mesh refinement is seen to increase the accuracy of the models' response predictions. The models achieve identical response predictions in the …

Development and experimental validation of self-centering buckling-restrained braces with shape memory alloy
… and the residual drift that may result from the inelastic response can make a building difficult, if not financially unreasonable, to repair after an earthquake. As a result, development of systems that return to their initial position (i.e., “self-center”) following an earthquake and minimize …

Cyclic Uniaxial Constitutive Model For Steel Reinforcement
… to cyclic strain histories which lead to inelastic response. In the case of rare, strong earthquakes, inelastic buckling and even rupture due to low-cycle fatigue can also occur. The understanding and characterization of the performance of RC structures under earthquake hazards requires …

Seismic loss assessment of sequential rupture of New Madrid Seismic Zone on the Central US
… the NMSZ is essential to generate an efficient response from FEMA and its associates and to educate and prepare the general population. The objective of this project is to provide scientifically defensible earthquake impact assessments with the most improved hazard, inventory, and fragility data …

Economic analysis of coffee supply in Kenya
… This is because the standard Nerlovian supply response model is not appropriate for a perennial crop such as coffee. The results of the estimated function are used to estimate the changes in producer surplus of the coffee farmers in Kenya. Separate estimates are obtained for estate producers …
