## Analysis and Behavior of StructuresOffering students a presentation of classical structural analysis, this text emphasizes the limitations required in creating mathematical models for analysis, including these used in computer programs. Students are encouraged to use hand methods of analysis to develop a feel for the behaviour of structures. |

If a rigid body in equilibrium under the action of any force system is

small rigid-body displacement and rotation, the work done by the force system is

zero. There are two important provisions of the principle that need to be pointed ...
