What is redundant reaction in structural analysis 2? - Quora

    https://www.quora.com/What-is-redundant-reaction-in-structural-analysis-2
    In statically indeterminate structures conditions of equilibrium are not enough to determine the unknown external support reactions. The reactions which are in excess of equilibrium equations are termed or treated as redundant reactions or simply ...

Indeterminate Beam with Vertical Reaction as Redundant

    determine reactions and draw moment diagram for the primary structure; Calculate the support reactions of the released structure. The resulting system, (B0 indicates the resulting deflection or deformation at the location of the removed redundant for the primary structure).Figure 3 - Support reactions

    In this case, R B and R C are unknown reactions. Each unknown reaction causes a deflection at both support locations. The final step (and the key to solving indeterminate beams) is to apply the compatibility equation(s). There must be one compatibility equation per redundant support. In this case, there are two, giving

Chapter 5: Indeterminate Structures – Force Method

    • Example 2: Compute the support reactions of the beam. Example 5.1.3, pages 254-256. 3. Force Method for Frames – One Redundant Force • Indeterminate frames can be solved in the same manner as indeterminate beams. If the frame is statically indeterminate to degree one, then one of the support reactions must be selected as the redundant.

What is redundancy in structure engineering? - Quora

    https://www.quora.com/What-is-redundancy-in-structure-engineering
    Aug 01, 2014 · A redundant or indeterminate structure has more structure than is absolutely necessary. So, if some part of the structure is damaged or removed, the structure will not necessarily fail or collapse, as another part can bear the load of the damaged ...

Force Method for Analysis of Indeterminate Structures

    forces / support reactions and replacing them with (assumed) known / unit forces. • Using superposition, calculate the force that would be required to achieve compatibility with the original structure. • Unknowns to be solved for are usually redundant forces • Coefficients of …

8.2 Force Method using an External Reaction Redundant ...

    http://learnaboutstructures.com/Force-Method-using-an-External-Reaction-Redundant-Force
    For this beam, by removing the support reaction at C and then treating the equivalent reaction force as an external force, we have changed our $\ang{1}$ indeterminate system into a determinate system. This new determinate system, without the reaction support associated with the redundant force is called the primary system. Later, we will have a ...

    Once the redundant forces are calculated from Eq. (5), all other support reactions and internal member forces can be calculated using static equilibrium along with the appropriate free body diagrams. This is possible since the force method of analysis has been used to determine the redundant forces or the forces in excess of those
