Brochure

Fatigue damage of concrete is an important problem in long-term resistance and durability of concrete and reinforced concrete structures subjected to cyclic loading as railway sleepers, anchoring regions of prestressed bridges, or fundaments of wind power plants. Although fatigue, in particular testing of fatigue properties and modelling of material and structural response, is a well-covered topic for metals and similar materials, for concrete (and many other materials commonly used in civil engineering as masonry, timber, or composites) appropriate testing methods or numerical models giving reliable prediction of fatigue damage and fatigue crack growth are still under development, and there are only few experimental data available.

This special session will concentrate on fatigue behaviour of concrete and similar (cementitious, quasi-brittle) civil engineering materials, especially

- testing methods and fatigue tests for various types of cyclic loading (primarily in tension or in bending)
- fracture mechanics under fatigue load - measurement of fracture properties, numerical modelling
- evaluation of test results, approximation of S/N curves for concrete and cementitious materials
- numerical material models for fatigue crack initiation and development, or other damage caused by cyclic loading
- design and assessment of structures subjected to significant cyclic loads (applications, case studies)
