Elevator bank layouts

An office building has an elevator bank with 4 elevators where 2 cabs side-by-side are arranged opposite the other 2. Each of the elevators is 3500-pound capacity with an interior cab dimension of 6'8" x 5'4". What is the recommended corridor width at this group?
A. 8 feet
B. 9 feet
C. 11 feet
D. 12 feet

AnswerC. 11 feet. At 1.5-2 times the car depth (5'4), this could be a range, but 10 feet is a minimum for groups of 4 or more. Therefore C is the best choice.

  1. Facing banks of 4 or more cabs should have a minimum of 10ft lobby space. This is an update to a post from January that I reviewed recently.

What are the car stall dimensions for a compact car? Answer A compact car stall size can be set by each municipality and therefore varies. Generally it is 7ft 6in wide by 15ft 0in long. However, in Fresno CA it's 8 1/2ft x 16ft and according to an Iowa urban design manual, it's 7ft 6in by 16ft. ARE 4.0 exam prep: SPD

Radius of gyration

For column design, the radius of gyration incorporates area and the moment of inertia. This value represents the resistance of a cross-section to buckling, which in columns happens under a load parallel to its lesser dimension. The slenderness ratio is the ratio of a column's effective length (modified by K-value to account for its end conditions) to its least radius of gyration. For a W12x16 A36 steel column with a least radius of gyration of 0.773, whose ends are both free to rotate but fixed in translation (K=1), what is it's slenderness ratio? Answer Kl/r = (1)(12feet)(12in/ft) / 0.773 = 186.3 ARE 4.0 exam prep: SS
