Modified method for rainwater ponding on flat roofs
AbstractA method for the analysis of rainwater ponding on flat or nearly flat one-way and two-way roofs, published in 2007, is modified. The existing method appears accurate for roofs of continuous secondary members and profiled steel sheeting, but is far too pessimistic for roofs in which all composing parts are simply-supported. After summarizing the formerly published method, a modification is proposed in order to fit better with FEM-packages, considered in this context to be exact solutions. In essence, the stored water in the deflected secondary members and steel sheeting elements is estimated more properly. An easy way has been found how to adapt the existing spring-piston model in order to better account for the correct volume of accumulated water in the secondary members and profiled steel sheeting. An application example and discussion of the results complete the article.
