Restraint Stresses and Crack Width Control in Structural Concrete Members

In this course we investigate how concrete develops its mechanical properties and building on this knowledge, we examine how to accurately calculate the stress and how to limit the development of cracks in steel-reinforced concrete structures.

To understand these topics we examine the fundamental relationships between concrete characteristics, geometry of structural elements, stress, reinforcement and crack width. We present a computational model that can be used to calculate the minimum reinforcement taking account of all these factors, and a series of examples to show how this model can be applied in practice.

• Fundamentals and background knowledge on crack control in concrete and steel structures according to the current standard
• Calculation of stress loading and estimation of cracking risk with special focus on concrete composition and after-treatment
• Deformation-based limitation of cracking due to stress
• Superimposition of early-age and later stress/cracking and of stress and load

• Civil & structural engineers in design, construction and management
