Abstract: A model for evaluating structural damage in reinforced concrete structures under earthquake ground motions is proposed. Damage is expressed as a linear function of the maximum deformation and the effect of repeated cyclic loading. Available static (monotonic) and dynamic (cyclic) test data were analyzed to evaluate the statistics of the appropriate parameters of the proposed damage model. The uncertainty in the ultimate structural capacity was also examined.

Hysteretic models that incorporate strength and stiffness deterioration
TL;DR: In this paper, three basic hysteretic models used in seismic demand evaluation are modified to include deterioration properties: bilinear, peak-oriented, and pinching, and the models incorporate an energy-based deterioration parameter that controls four cyclic deterioration modes: basic strength, postcapping strength, unloading stiffness, and accelerated reloading stiffness deterioration.

Probabilistic Capacity Models and Fragility Estimates for Reinforced Concrete Columns based on Experimental Observations
TL;DR: In this article, a methodology to construct probabilistic capacity models of structural components is developed, which properly accounts for aleatory and epistemic uncertainties, and is used to estimate the fragility of a typical bridge column in terms of maximum deformation and shear demands.

Comparative Bond Efficiency of Deformed Concrete reinforcing Bars
Arthur P. Clark
- 01 Nov 1946
TL;DR: In this paper, three tests were made of each variable for each design of deformation and it was established that a certain group of the bars was definitely superior to the others, in the sense that their average rating was significantly higher than the average of the others.
