411 Quick & Cheap Design Calculations
A building control officer says that he recently received a set of calculations which had been prepared through a website that specialises in providing calculations at a very low price. They do this by having a number of generic designs which are then adapted to the purpose.
This has been published because of concerns brought to the attention of SCOSS about collapses of tension structures in buildings and tunnels in recent years. Some have resulted in fatalities and numerous injuries. Examples are given of failures caused by faulty hangers and by defective post-drilled fixings. Recommendations are made for inspecting older tension systems particularly those whose failure might have catastrophic consequences. General advice, with reference to industry standards and codes, is given on the selection and installation of new anchors.
During the recent series of storms in the UK there have been multiple occurrences of flooding and wind damage, many of which will have structural safety implications. Confidential Reports about these can be sent to Structural-Safety and lessons to be learned will be circulated to help safeguard against the effects of future extreme weather events.

Since the last 2012 Newsletter there have been two major collapses of shopping mall roofs: one which was under construction near Durban killed two, and the other in Latvia which killed fifty four. The lesson to be learned is that large numbers of people congregate underneath shopping mall roofs which are safety critical structures deserving close attention during design, construction, and maintenance.
About Structural Safety
Structural Safety combines CROSS and SCOSS to work with the professions, industry and government on safety matters concerned with the design, construction and use of building and civil engineering structures. It:
CROSS (Confidential Reporting on Structural Safety) aims to improve structural safety and reduce failures by using confidential reports to highlight lessons that have been learnt, to generate feedback and to influence change. SCOSS (The Standing Committee on Structural Safety) is the independent body established in 1976 to maintain a continuing review of building and civil engineering matters affecting the safety of structures. SCOSS aims to identify in advance those trends and developments which might contribute to an increasing risk to structural safety.

The programme depends on receiving reports and individuals and firms are encouraged to participate by sending concerns in confidence to Structural Safety.
