Comparative Merits of Different Construction Materials
In Energy-Absorption Capacity a
a
Assume 12% reduction of basic proportional limit of extreme fiber strew in bending at 5,270 psi, allowing for knots.
B
Assume the supported length of pile as 50 feet.
c
Number of piles required to absorb 450 in.-tons of designed capacity (transient-load allowable working stress) or to absorb 1,350 in.-tons of maximum
capacity (stressed at nearly the safe elastic limit of materials).
d
Assume the ship berths broadside with a length of contact of 150 feet, which is the shortest parallel wall side of cargo ship
