Conducted to monitor everyday functionality, focusing on crack control and deflection limits.

Where $\varepsilon_sm$ is the mean strain. To satisfy this easily, engineers often use the method:

) must not exceed specific thresholds defined by exposure classes (typically for regular structures, or reduced to if checking for water tightness via EN 1992-3).

Case B: Max Lateral Pressure (High fill, no traffic, lateral surcharge). Case C: Max Uplift (Empty culvert, high groundwater). 4.

Under the characteristic combination of actions, compressive stress in the concrete must be limited to prevent longitudinal cracks:
