What is the seismic design story shear Vx in story x equal to?

• The lateral forces acting at the floor or roof level supported by that story and all of the floor levels above

• The total shear in any horizontal plane of a structure subject to lateral loads

• The horizontal movement of a structure in response to a lateral load

• The raising of a structure or portion of structure in response to an overturning moment or wind suction

What are P-delta effects related to in a structure?

• Second-order effects on shear, axial forces, and moments introduced during displacement of a structure

• The horizontal movement of one level of a structure relative to the level above or below

• The distance required to avoid contact between separated structures under deflection from seismic action or wind forces

• The rapid oscillations of a flexible cable or membrane structure caused by the aerodynamic effects of wind

What is the seismic-force-resisting system responsible for in a building's structural system?

• The distance required to avoid contact between separated structures under deflection from seismic action or wind forces

• The horizontal movement of one level of a structure relative to the level above or below

• The maximum ratio of story drift to story height allowed by a building code

• Providing the required resistance to the prescribed seismic forces

What is the purpose of redundancy in a structure's lateral-force-resisting system?

• The raising of a structure or portion of structure in response to an overturning moment or wind suction

• The rapid oscillations of a flexible cable or membrane structure caused by the aerodynamic effects of wind

• The horizontal movement of a structure in response to a lateral load

• Providing multiple paths for a load to travel from a point of application to a point of resistance

What does the term 'building separation' refer to in structural engineering?

• The distance required to avoid contact between separated structures under deflection from seismic action or wind forces

• The horizontal movement of one level of a structure relative to the level above or below

• The total shear in any horizontal plane of a structure subject to lateral loads

• The rapid oscillations of a flexible cable or membrane structure caused by the aerodynamic effects of wind
