Abstract

FEA simulation of the double load-bearing system (LBS) for Pisa Tower is provided. Cylindrical trunk (T-LBS) is surrounded by 6-stage column system (C-LBS) in the telescopic manner. T-LBS is found out as the main object to bear the tower’s weight. Trunk is rigid and low-stressed. CLBS is partially (about 44 % of mass) hanging on the trunk by pliable cornices. Slender C-LBS is over-stressed in the bottom colonnade (up to 4.5 MPa in the initial upright position). Column’s stress field inspection and column length tuning are recommended for the bottom colonnade of the Tower to prevent local fracture.
