Download the sample of Protral analysis project to present ready research
Friends who are going through steel or concrete projects usually always face a problem called portal analysis. One of the parts that always takes a lot of time in building calculations is the analysis of the structure against lateral loads. In this field, several methods have been presented, one One of them is portal analysis, which unfortunately is not taught in the course of structural analysis, so there are many students who deal with portal analysis to perform manual calculations for their projects, and they usually encounter problems, that is why I tried to briefly and usefully I will explain the method to my friends along with an example solution, I hope it will be useful.
