Abstract
A reinforced concrete pier manifested cracking and spalling at its top slab/wall joint, apparently due to twisting of the top 1:5-m-thick slab. The pier supports a kiln at one of its tires, through two steel rollers. Field and laboratory tests and structural analyses were performed to determine the cause and extent of the problem and to recommend a remedial measure. It was found that torsional moments result when the tire contacts with only one of the rollers on top of the pier. It was also found that the walls and top slab of the structure were not provided with adequate steel reinforcement to take care of the torsional moments. This, in addition to the low strength of concrete, has caused cracks to develop. The problem was solved by repairing the defective joint and other areas, and then casting a heavily-reinforced 240-mm-thick shotcrete jacket around the exterior of the structure.
