Of interest to many involved in lightweight structures, and in particular tension membrane structures, are the new requirements related to fire. These new requirements have been the result of a number of fatal fires in Australia and overseas. See this article for an interim report related to fires and cladding.
An Interim Report has now been published by the recently formed Victorian Cladding Taskforce.
Prepared by the Tensile Membrane Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE
Standard ASCE/SEI 55-16 provides minimum criteria for the analysis, design, and performance of membrane-covered cable and rigid member structures, collectively known as tensile membrane structures. It is applicable to both permanent and temporary structures.
Within CEN/TC 250/WG 5, CEN/TC 248/WG 4, the TensiNet Association and COST Action TU1303, an international team of researchers, engineers, architects, material producers and manufacturers has been working on this report, which provides background information in support of the implementation and development of a future Eurocode for the Structural Design of Tensile Membrane Structures.
Tensioned Membrane Structures have unique properties compared to the more conventional built environment. Besides their low self-weight and high flexibility these structures are known to be 'optimally' constructed, as they are only loaded in tension. It results in shapes adapted to the flow of forces and a minimum of material needed to realise the span.
Important revisions have taken place for fire detection and control in buildings across a number of Standards.
These set out the minimum requirements that should be in place during design and construction to ensure compliance.
Recent revisions include:
The use of ventilation and air conditioning in buildings - Fire and smoke control in buildings
Fire detection, warning, control and intercom systems - System design, installation and commissioning
Fire detection, warning, control and intercom systems - System design, installation and commissioning - Emergency warning and intercom systems
