Wind loading

From one story (storey) to the next, the maximum drift allowed is equal to 0.0025 x the height of the story. If the story height is 11 feet, what is the maximum drift allowed? Answer 0.0025 x 11ft x 12 in/ft = 0.33 inch ARE 4.0 exam prep: SS

Exits and exit access

The maximum occupant load for one exit in this illustration is 49. For which occupancies is this applicable? (Select 4) A. A, B. B, C. I D. S, E. Fm F. M

Pressurization

An imbalance in air pressure is apparent in this illustration, indicating that _________ is inducing ________. Select two words to fill in these blanks. A. duct leakage B. negative pressure C. infiltration D. positive pressure E. increased supply fan rate Answer Duct leakage (A) induces infiltration (C), illustrating negative pressurization. Ensuring the supply fan rate is greater than sum of the return and infiltration rates will positively pressurize the building. Eliminating duct leaks will resolve the initial cause.

Curved roads

Horizontal road alignment employs several common configurations for curved roads. Two curves in the same direction that are connected by a minimum 200ft tangent is a ________ curve. A. simple B. reverse C. compound D. broken back Answer D. broken back curve, and the two curves should have equal radii. ARE 4.0 exam prep: SPD

Imageability

Select 5 components that contribute to imageability , Lynch's concept that posits that a highly imageable city is readily understandable and distinct. A. districts B. social structure C. edge D. landmark E. nodes F. overlapping systems G. paths H. legibility Answer A, C, D, E, G are components that contribute to defining imageability. ARE 4.0 exam prep: PPP

Bolted connections

The connection illustrates which of the following designations? (Choose 2) A. SC B. N C. X D. S E. D Answer C. X (bearing type connection with threads excluded from the shear plane) and D. S (bolt in single shear) ARE 4.0 exam prep: SS

Foundations

What soil or site conditions would require this foundation type? A. soil near grade is not appropriate for spread footings, and side friction is desired B. low soil bearing or heavy load ratio to soil pressures C. exterior column is too close to property line for footing to extend D. where grade beam is required to transfer loads to piles Answer A mat or raft foundation is used when there is B. low soil bearing or heavy loads ratio to soil pressures. ARE 4.0 exam prep: SPD

End conditions

The buckled shape (dashed) of the steel column is shown for the following top end condition: A. fixed in rotation, free in translation B. fixed in translation, free to rotate C. free to both rotate and move side to side D. fixed in rotation, fixed in translation Answer A. fixed in rotation, free in translation (bottom is rotation free and translation fixed). ARE 4.0 exam prep: SS

CPM logic

In this Critical Path Method scheduling fragment, what must occur prior to Activity C? A. Activity A B. Activity B C. Both A and B D. Nothing Answer C. Both A and B must precede Activity C (same is true for Activity D). ARE 4.0 exam prep: PPP

Municipal water supply

In order to control the flow of water from a public water supply main to a service pipe, which of the following is necessary A. curb box B. building shut-off valve C. corporation stop D. check valve Answer C. corporation stop, installed off the main, but before the curb box (curb box provides access to a water meter and the emergency control valve to the building). ARE 4.0 exam prep: BS

Shear & Moment double-post!
