Modification Of Kani’s Method for One Storey One Bay Portal Frame with Inclined Columns

Abstract

Looking to the preset trend of analysis and design, particularly in analysis, people prefer the analysis method which gives the perfect results with least amount of effort. The rotation contribution method presented by Gasper Kani of Germany is excellent method of analysis. The rotation contribution method is smart extension of the slope deflection method. This is an iterative method. The rotation contribution method has simplicity of the moment distribution method. The rotation contribution method has overcome some disadvantages of the moment distribution method. The rotation contribution method is self corrective in nature. Even if an error committed in the calculation it gets automatically corrected in the course of further work.The conventional rotation contribution method is not applicable for the analysis of the frames with inclined columns. The rotation contribution method is excellent extension of the slope deflection method. To apply the conventional rotation contribution method to analyze the frames with inclined columns, it has to be modified. The conventional rotation contribution method can be modified with help of the slope deflection method.
