PTI Earthquake Performance Of Unbonded Post Tensioned Buildings
One of the strongest earthquakes ever to hit California shook hundreds of post tensioned buildings on October 17, 1989, with an intensity of 7.1 on the Richter scale. The earthquake, named Lorna Prieta, had its epicenter approximately 65 miles southeast of downtown San Francisco. Widespread damage was caused in the vicinity of the epicenter and as far as San Francisco and Oakland. Many post-te…

Will nonlinear backcalculation help?
Backcalculation of FWD data often results in unrealistic layer moduli. The modulus of the subgrade may be two to three times the expected value, and the modulus of an intermediate granular material may be lower than the subgrade modulus. If stresses or strains measured in the pavement are compared with theoretical values, the agreement is often poor. All theoretical models for calculating pa…
