Abstract
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 produces a differential shortening and a relevant bending moment increase in main structural elements. In the first place, it is shown how axial shortening due to creep affects to a 30-storey tall building ...
