چکیده مقاله:
The direct method of analysis is a new method that has been introduced into the draft law since 2005 in the US Steel Structures Act, and in the yea2010 was recognized as the main method. One of the most important advantages of this method is the lack of the need to calculate the effective coefficient of length (which causesapproximation In the calculations), considering the overall stability of the structure along with the stability of the single pillar and the ability to apply directly to a variety of structural systems point Made This method takes into account all the parameters that affect sustainability. The requirements of this method for analysis, taking into account the effects of the orderThe second is in the analysis that the appropriate boost described in this article should be considered. Also consider nonlinear effects inThis method makes it impossible to disprove the principle of this method. This method also effects the geometric defects in the construction and installation Considers. In this paper, while the philosophy of this method, as well as the effective length method, is fully described, it is finally presented with the results.From the design of several frames, using two methods, the advantages and disadvantages and the results obtained from the two methods are compared
