Analytical characterisation of axial shortening due to creep of reinforced concrete columns in tall buildings

This paper proposes a new methodology to analyse how creep affects to reinforced concrete columns of tall buildings with central core that range between 20 and 40 floors. Creep shortening is due to compression stresses and are the different stress values between central core and columns which produc...
