Abstract
In cold climate regions, the life span of concrete structures can be significantly
reduced if the mechanical properties of critical components of a structure are
affected by the deterioration caused by simultaneous fatigue loading and freezing
and thawing cycles. This makes the residual mechanical properties of the
constitutive concrete material an important design consideration, after years of
exposure in such a climate.
The objective of the research program was to evaluate the residual mechanical
properties of plain and Fiber Reinforced Concrete (FRC) (hooked-end steel,
corrugated steel, and polyolefin fibers) exposed to several combinations of
freezing and thawing cycles and flexural fatigue loading cycles. The residual
mechanical properties (flexural strength, fl
