External indeterminacy of a structure
Did you know?
WebThus, a plane structure that is statically determinate externally must be supported by exactly three reactions. Some examples of externally statically determinate plane structures are shown in Fig. 3.9. It should be noted that each of these structures is supported by three reactions that can be determined by solving the three equilibrium equations. WebTo determine whether a structure is externally determinate, the following equations are used: (1) Statically unstable externally: r < 3 + e c (2) Statically determinate externally: r = 3 + e c (3) Statically indeterminate externally: r > 3 + e c where r is the number of reaction … If a structure is internally determinate, then all of the reactions and internal forces …
WebSep 12, 2024 · When all the forces in a structure can be determined strictly from the three equations of equilibrium, the structure is referred to as statically determinate. Structures having more unknown forces than available equilibrium … WebThe degree of static indeterminacy (DSI) of a structure tells us which methods are suitable for analysing it. If a structure is statically determinate, i.e., DSI=0, then it suffices to use equilibrium to determine the section forces. ... support reactions beyond six implies external indeterminacy. The rest of the DSI number represents degrees ...
WebMar 5, 2024 · A determinate structure is one whose unknown external reaction or internal members can be determined using only the … WebClassify each structure shown below as stable or unstable. If stable, determine whether they are statically determinate or statically indeterminate. Explain your reasoning. If statically indeterminate, specify the degree of statical indeterminacy. All structures are planar and movements in out-of-plane direction are prevented. a) r = 6, n = 2 r ...
WebDec 30, 2024 · External indeterminacy is difference between total number of support reactions and the number of available static equilibrium equations. ∴ Ds e = (total number of support reactions) - (available equilibrium equation) Internal indeterminacy is indeterminacy in excess of external indeterminacy. ∴ Ds = (total indeterminacy) - …
