Topic 8 ( ANALYSIS OF TRUSSES ) Flashcards
Keywords: Straight bars, triangular pattern
Definition: A structure composed of straight, slender bars connected at joints, arranged in a triangular pattern to carry loads efficiently over long spans.
Truss
Keywords: Stretching force
Definition: A force that pulls and elongates a truss member.
Tension
Keywords: Shortening force
Definition: A force that pushes and shortens a truss member.
Compression
Keywords: Joint equilibrium, forces
Definition: A technique for analyzing trusses by isolating and applying equilibrium equations (ΣFx = 0, ΣFy = 0) at each joint.
Method of Joints
Keywords: Cut, internal forces
Definition: A technique that involves cutting through a truss and analyzing a section using equilibrium equations to find forces in specific members.
Method of Sections
Keywords: No load, simplification
Definition: Members in a truss that do not carry any force under specific loading conditions, identified by geometric and loading rules.
Zero-Force Members
Keywords: Connection point
Definition: A point where two or more truss members are connected, assumed to be a pin connection in truss analysis.
Joint
Keywords: Applied forces, structure interaction
Definition: Forces applied to a truss at its joints, such as concentrated loads or distributed loads converted to joint forces.
