WebI have a question about the methods to decide whether a beam/frame is determinate or indeterminate. Typically you can count the number of reaction forces and compare them to the number of elements to determine this. The typical equation for a determinate beam is r = 3 N, where, r is the number of reaction forces and N, the number of elements. WebNov 27, 2012 · Analysis of Statically Determinate Structures !

WebApr 17, 2024 · The virtual work method, also referred to as the method of virtual force or unit-load method, uses the law of conservation of energy to obtain the deflection and slope at a point in a structure. This method was developed in 1717 by John Bernoulli. To illustrate the principle of virtual work, consider the deformable body shown in Figure 8.1.
