92 Finite Element Analysis and Design 6. In the structure shown, rigid blocks are connected by linear springs. Imagine that only horizontal displacements are allowed. Write the structural equilibrium equations [ ]{ } { } K Q F after applying displacement boundary conditions in terms of spring stiffness k i , displacement DOFs u i , and applied loads F i . Solution: Let the two fixed points to be Nodes 4 and 5. The element matrix equation for each element can be written as (1) 1 1 1 1 1 1 4 4 k k u f k k u f         , (2) 2 2 5 5 (3) 2 2 3 3 k k u f k k u f     (3) 3 3 1 1 (3) 3 3 3 3 k k u f k k u f     , (4) 4 4 1 1 (4) 4 4 2 2 k k u f k k u f  
