Structural Integrity Solutions for Education Facilities

As well as requirements for uniform distributed loads, wind pressures, impact resistance and security also need to be considered.

Smart Structural

Gyprock provides tested system recommendations that meet the functional needs and structural integrity compliance requirements for education facilities. These are outlined in the Gyprock Education Design Guide with a much wider selection available through the online System Selector and The Gyprock Red Book.

An important criteria for structural integrity in walls is impact resistance. The following plasterboards have been designed with higher levels of soft body impact resistance, hard body impact resistance, surface indentation resistance, sag resistance or combinations of these:

These plasterboards are recommended by Gyprock in wall and ceiling systems to meet functional needs and structural integrity compliance requirements for education facilities including:

  • Corridors and foyers
  • Gymnasiums
  • Stairway walls and isolated passages
  • Service shafts and plant rooms

BCA Structural Integrity Requirements for Education Buildings

Fire rated walls classified as lightweight must meet the requirements of Clause C1.8 of the BCA for Uniform Distributed Loads (UDLs). The Clause and Specification specify performance values based on static pressure, impact bag drop height and surface indentation, and require the linings to meet manufacturing standards.

Structural Test Requirements

Wall Static Pressure Bag Drop Height Surface Indentation
Walls generally 0.25kPa 100mm 5mm impression from steel ball
Walls of shafts and fire isolated exits 0.35kPa 150mm 5mm impression from steel ball

Hard Body Impact Resistance

Hard body impact occurs when a solid object comes into contact with a wall with direct force. In education buildings, schoolbags, sports equipment and projectiles can all pose hard body impact risks.

Soft Body Impact Resistance

Soft body impact generally refers to situations where someone falls against a wall, exerting pressure over a larger area than that of a hard body point force. Crowded hallways or accidental tripping in any situation can often lead to a soft body impact event.

Surface Indentation Resistance

Both hard and soft body impact events involve a high level of direct force on the wall. Surface indentation impact could be described simply as scrapes and bumps – more of an oblique or glancing force. Surface indentation damage is a risk in most situations where there is movement of people or objects in close proximity to a wall.

Design Pressure

Internal walls may also be subject to wind pressure. This occurs if doors or windows in external walls are assumed to be open or broken during wind events, and the pressure value is related to the site, the building height and the degree of openings. Where pressures are provided by the project engineer, framing sizes for internal walls can be selected from the appropriate height table found in the Gyprock Education Design Guide.


Security can be an important design consideration. The BCA contains no provisions for the security aspects of walling systems but Gyprock Security Wall solutions are available if required by the design brief.
