SR57 Serviceability limit state criteria for New Zealand buildings (1999)

This report details serviceability criteria for New Zealand buildings. Its aim is to assist structural engineers and designers with decisions on deflection limits for various building components.

This report ascribes serviceability criteria for different conditions and controls. The report primarily focuses on a table of suggested criteria for different materials and structural systems being used in various applications.

It discusses the background and rationale for each criterion and includes typical values of movement-related parameters for materials commonly used as building elements.

The final section of the report deals with designing against floor vibration problems. This includes discussion as to the nature of the problems, the various common forms these problems take and presents some of the more common methods of design assessment used to predict problem floors. Some worked examples are included to more fully describe these methods.
