Importance Of Building Structure
There is limited information available in the public domain about the building internal frame and it is highly critical for the vulnerability assessments. Geoscience Australia and Attorney Generals Department have conducted engineering survey of major cities in Australia. That provides the structural system of the buildings in three heights, lower, middle and upper portion of the buildings. Some of this information can be derived using expert knowledge and the variables may be the height, year built, size and location of the building.
7.3 Building External Wall:
External walls provide a barrier against the outdoors and support roof and any upper storeys. Interior walls might help carry weight from the roof, hide plumbing or wiring, help insulate the building, or simply divide interior space for functionality. As building structure is supported by external walls, the information is highly critical to assess the risk and also to protect the people living in. If the external wall is damaged due to severe winds, then the wind enters into the building that lifts the roof and damage the entire structure. So the external wall information is important for the risk assessment from natural …show more content…
Consequently, this is considered as required for inclusion into the national exposure information database in Australia. NEXIS has collected the data for some states and generalised for national consistency. For rest of the country, a desktop survey was conducted and applied statistically for the entire building stock in those areas.
At the national level, NEXIS contains information on number of residential buildings by different wall types that can be aggregated at state level and ASGS SA2 and SA1 levels.
There are no standard wall types defined in Australia and mapped. The wall type in Australia varies with the location, materials and age of the construction. The building wall type data is not collected using standard approach across Australia. Some of the states like Tasmania and South Australia have this data and need to be mapped to a standard wall types.
