Condition assessment of two prestressed concrete slabs after 60 years in service
نویسندگان
چکیده
Two concrete deck slabs extracted from a Canadian bridge have been evaluated using non-destructive testing (NDT), followed by destructive testing. Throughout its service life, the experienced harsh environmental conditions with frequent freeze-thaw cycles, hot and humid summers, use of de-icing salts during winters. This study presents preliminary results an exhaustive condition assessment two prestressed slab panels, where NDT techniques (visual assessments, electrochemical soundness tests) conducted prior to Although visual inspection did not indicate poor quality, ultrasonic pulse velocity showed that both are quality may be suffering internal defects. Chlorides also introduced through strand conduit anchor points. These findings raise concerns regarding structural integrity corrosion-affected members.

D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...
