Equilibrium and Reactions,tions provided by the supports. The concept of equilibrium is developed further in the following chapters to deal with hypothetical parts of the structure, and thereby obtain knowledge of the distribution of the forces inside the structure.

Equilibrium and Reactions,he present book deals with buildings and civil engineering structures that are supported to prevent motion, as opposed to space structures, trains etc. where motion is an integral part of the behavior. A fundamental tool of statics is the concept of equilibrium. In order to remain stationary the tot

Truss Structures,connected to the joints in a manner that permit rotation, and thereby it follows from equilibrium considerations, that the individual structural members act as bars, i.e. structural members that can only carry an axial force in either tension or compression. In a statically determinate truss all the
