- Why does the maximum snow load occur simultaneously with the maximum dead and live loads?The magnitude of a uniformly distributed load is 2 KN/m applied on a span of 5 meters. What is the equivalent concentrated load?In designing for a wind loading, a high-rise building cannot be considered independent of its surroundings because the configuration of nearby buildings and natural terrain has a substantial influence on design loads. Briefly discuss what is the best approach or method to predict the wind loads to high rise buildings before they can be built? You may indicate why you choose this method.
