| Abstract: | As statically determinate planar rigid frame is a structure consisting of a number of components that are all under complex stress. Based on the different moduli theory, the formula of neutral axis, normal stress, and shear stress of the structure is derived. Solution to the problem is presented with a computation example. In addition, results of a finite element program are compared with the analytical solution. Finally, difference between the two methods is analyzed and conclusions drawn. |
