[DOWNLOAD] Annual Probability of Exceedance for structures in New Zealand according to AS-NZS 1170


In this post an Excel spreadsheet based on the AS/NZS 1170 is available. Scope of the tool is to define the Annual Probability of Exceedance, P (and, hence, Average Recurrence Level, R), for Ultimate State Limit and Serviceability Limit States. The values are referred to New Zealand, as per Section 3, Table 3.3. The Annual […]

Regional wind speed according to AS/NZS 1170:2


In order to obtain the design wind speed to be used in the calculation of design wind pressure, a regional wind velocity and a site wind velocity must be calculated. VR, the Regional wind speed, is defined as a 3-second gust wind speed. It is an all-directional basic action because no considerations on direction from which wind gust is […]
