Prediction of Stress Increase at Ultimate in Unbonded Tendons Using Sparse Principal Component Analysis
Abstract While internal and external unbonded tendons are widely utilized in concrete structures, an analytical solution for the increase in unbonded tendon stress at ultimate strength, $$\Delta f_{ps}$$ Δfps , is challenging due to the lack of bond between strand and concrete. Moreover, most analys...
