      18 kips ESALs for vehicle: (Using Table 4.2 and 4.3) Truck . A: 12 kip single axle = 0.222. 23 kip single axle = 2.574 Total 18-kip ESAL = 2.796. Truck . B: 8 kip single axle equivalent = 0.047. 43 kip tandem axle equivalent = 2.706 Total 18-kip ESAL = 2.753. RESULTS: Truck A will cause little more damage but both damages caused by trucks are ...

      For sites where the Acceleration Coefficient "A" in AASHTO is less or equal to 0.05, static design considerations govern and dynamic performance or design requirements may be omitted. For sites where the Acceleration Coefficient is greater than 0.29, significant total lateral structure movements may occur, and a seismic design specialist should ...
