Parking structures in Northern climates take a beating. Road salts, freeze thaw cycles and thermal expansion/contraction all conspire to undermine unprotected structures.
CKC met this problem head-on in the design of the 1,600-car Kenton County Parking Structure. Microsilica was specified to densify the concrete and prevent the ingress of chlorides. Calcium nitrite was used to create a passivating layer around the reinforcing steel and neutralize corrosion causing chemicals. Other major durability enhancing features included a low water to cement ratio and added concrete cover over the reinforcing steel. The result is a structure able to withstand even the harshest climatic conditions.
To eliminate shear walls, lateral loads are carried by the transverse gravity frames and longitudinal ramps. This maximizes visibility and security, an important operational concern for large urban parking structures.
