Shear wall
A picture shows a section of a building consisting of a roof, a horizontal floor, two walls (one a shear wall) opposite each other and two frames – one rigid and one braced frame – opposite each other. Arrows represent loads that travel across the roof from the braced frame towards the rigid frame, and from the rigid frame across the roof towards the braced frame. The arrows from the braced frame also run along the top and bottom of the shear wall (towards the braced frame at the top and away from it at the bottom), as well as up the shear wall from the bottom corner near the braced frame and down the shear wall on the bottom corner near the rigid frame.  
The following text is shown:
Rigid frame: A steel or reinforced concrete frame with rigid joints will resist changes resulting from forces in different directions.
Shear wall: A wood, concrete or masonry wall will resist changes in shape. The wall will transfer lateral loads to the foundation.
Braced frame: The frame is timber or steel and is braced with diagonal members.
Horizontal floor: A rigid floor structure is like a deep flat beam. The floor transfers lateral loads to the shear walls and to the braced or rigid frames.
