- 1 - F F Chapter 1 Structural Mechanics Introduction There are many different types of structures all around us. Each structure has a specific purpose or function. Some structures are simple, while others are complex; however there are two basic principles of composing structures. They must be capable of carrying the loads that they are designed for without collapsing. They must support the various parts of the external load in the correct relative position. A structure refers to a system with connected parts used to support a load.
- 6 - roller support: this support carry only shear forces between jointed members.The roller support allows rotation and one displacement of the support point: u A ≠ 0; v A = 0 and ϕ A ≠ 0. spring supports: These supports are like the previous but with the difference that they are not ideally rigid but with some real stiffness.
