Lateral Forces Quiz

Question 1

T/F In a rigid diaphragm the wall parallel to the force resist the force equally?

Answer 1

True

Question 2

T/F In a flexible diaphragm the walls parallel to the force resist the force equally?

Answer 2

False, if the diaphragm is flexible then the walls resist the force proportional to their R (rigity) factor

Question 3

In order to add rigidity to a colonnade what type of structural member (3/4” Steel Rod, 4” Steel Pipe, Beam) could be added?

Answer 3

Steel Pipe and Beam

Question 4

With regard to earthquake engineering, what is the meaning of R?

Answer 4

It is the Coefficient representative of the inherent over-strength and global ductility of the load force resisting system.

Question 5
