Quando se trata de cargas de vento em estruturas do tipo edifício de acordo com a ASCE 7, podem ser encontrados inúmeros recursos para suplementar as normas de dimensionamento e ajudar os engenheiros com esta aplicação de cargas laterais. However, engineers may find it more difficult to find similar resources for wind loading on non-building type structures. This article will examine the steps to calculate and apply wind loads as per ASCE 7-16 on a circular reinforced concrete tank with a dome roof.
In the AISC 360 – 14th Ed. C2.2, the direct analysis method requires initial imperfections to be taken into consideration. The important imperfection of recognition is column out-of-plumbness. According to C2.2a, the direct modeling of imperfections is one method to account for the effect of initial imperfections. However, in many situations, the expected displacements may not be known or easily predicted.
