Framing & StructuralQuestion 348 of 700
A 'collector' or 'drag strut' in a lateral system does what?
a.Collects rainwater from the roof
b.Provides gravity support only
c.Gathers diaphragm forces and 'drags' them into the shear wall that is shorter than the diaphragm edge
d.Serves as a decorative beam
Explanation
A collector (drag strut) is a framing member that gathers the lateral force along a diaphragm edge and delivers it into a shear wall that does not run the full length of that edge, keeping the load path continuous. It has nothing to do with rainwater, gravity-only support, or decoration.
