Example It is required to determine the approximate values of moment, shear and axial force in each member of frame as shown in Fig. Portal Frame; 7. (b) Determine all the reactions at supports. 10. If the frame is statically indeterminate to degree one, then one of the support reactions must be selected as the redundant. An example indeterminate frame that may be solved using the portal method is shown in Figure 7. Only the 2nd frame has edge constraints assigned to it. Moment‐Distribution Method • Classical method. Comparison with other methods If the frame is designed according to the forces determined from the Portal Method or Cantilever Method, the frame will be safe but not necessarily efficient. This example also introduces new kinds of static and dynamic analyses. Porter's Five Forces Analysis is an important tool for understanding the forces that shape competition within an industry. This will take time, but the links are key to increasing competitive advantage from the value chain framework. Pages 73 p.
