Before revision: Serviceability limit state (SLS) 1) limit state of deflection 2) limit state of cracking 3) limit state of vibration In addition to the ULS check mentioned above, a Service Limit State (SLS) computational check must be performed.
After revision: Serviceability limit state (SLS)  In addition to the ULS check mentioned above, a Service Limit State (SLS) computational check must be performed.
