Presentation Transcript
Basic Structural Theory Concepts and construction
Forces Vertical (y-axis only)
Forces Lateral (x-axis only)
Forces Rotational – Moments and Bending
Connections Pin Constrain x & y Rotate freely
Connections Pin Constrain x & y Rotate freely
Connections Pin Constrain x & y Rotate freely
Connections Fixed / Moment-Resisting Constrain x & y Constrain rotation
Connections Fixed / Moment-Resisting Constrain x & y Constrain rotation
Connections Fixed / Moment-Resisting Constrain x & y Constrain rotation
