The report covers:


While previous manuals often worked with a 50-year return period for basic wind speed, the 2020 edition aligns more closely with risk categories. For essential civil infrastructure (hospitals, bridges, emergency centers), you will be designing for higher return periods (up to 500 years for ultimate limit states). The report covers:

Incluye mapas de isoyetas actualizados para periodos de retorno de 50, 100, 200 y 2000 años. Para obras civiles comunes (edificios habitacionales), el periodo de retorno es 50 años.

Where ( V_z = F_T \times F_rz \times V_R0 ), with ( F_rz ) = terrain-height factor: [ F_rz = \left( \fracz10 \right)^\alpha ] z = height above ground (m), α from terrain table.

  1. Yes! Please post the entire itinerary. Would love to hear about activities loved (and tolerated) by children of various ages.

    1. @Elisa – coming tomorrow! Some stuff was more liked than others of course, but so it is with family travel…

  2. I am excited to see your Norway itinerary. We can fly there very cheaply, so it is on my list. We went to Sweden last winter and my very selective eater loved the pickled herring, so who knows with these things.

    1. @Jessica- my selective eater did not even try herring, but one of my other kids did, as did I. Not my favorite, but hey. I did do liverpostai…

  3. Wow Norway! I am a little jealous. We could get there relatively easy but everything there is prohibitively expensive…

    1. @Maggie – the fun thing about traveling internationally with a foreign currency is that none of the prices feel real (well, until the bills come, at least…)
