![]() ![]() While displacement method of analysis of indeterminate structure is suitable when degree of freedom is less, i.e, degree of kinematic Indeterminacy is less than degree of static Indeterminacy. Once the redundant forces are calculated, the remaining reactions are. Solving these equations, redundant forces are calculated. Calculation Example Frame analysis Uniform Load Calculation Example Find the Center of Gravity (Surface) Calculation Example Design bolted connection of tension plates (EC3) Calculation Example Cantilever Beam. Force method of analysis of indeterminate structure is suitable when degree of redundancy is less, i.e, degree of static Indeterminacy is less than degree of kinematic Indeterminacy. In the force method of analysis: Primary unknown are forces in the members, and compatibility equations are written for displacement and rotations (which are calculated by force displacement equations) in this method. Find the Reactions Calculation Example Beam with inner hinge (Part B).While in case of displacement method of analysis of indeterminate structure, first force displacement equations are written and then unknown displacement are calculated from equilibrium equations at joints. In force method of analysis of indeterminate structure, first force displacement equations are written and then unknown forces are calculated from compatibility criteria. ![]() While in case of displacement method of analysis of indeterminate structure, the unknowns are taken as displacement (i.e, Δ or ө). In force method of analysis of indeterminate structure, the unknowns are taken as forces (i.e, member forces or reaction).If only the equilibrium equations are needed to solve for F, then the structure is statically determinate. To analyze an indeterminate structure, some additional equilibrium or compatibility equations are required. For Slope Deflection Method, you need 2 & 3. For an indeterminate structure, the condition of static equilibrium equations are not sufficient to analyze the structure. ![]()
