Serviceability Limit State
The Serviceability Limit State (SLS) refers to the condition where a structure remains functional, comfortable, and safe for everyday use without experiencing excessive deflection, vibrations, or other signs of distress. It's about ensuring the building or structure performs well under normal use, avoiding issues like cracks, noise, or discomfort for occupants. SLS focuses on practical aspects like appearance, durability, and user comfort, rather than safety in extreme conditions. Engineers design structures so they are not only strong and safe but also comfortable and practical during regular service life.
