| 摘要： | This project evaluated the application of super elastic shape memory alloy (SMA) reinforcement in combination with engineered cementitious composites (ECC) in bridge columns to minimize earthquake damage. Based on initial evaluation, Nitinol SMA and ECC compositions were selected for application in bridge columns. An analytical study was performed to determine optimum material properties and configuration for the concrete column. Bridge columns incorporating a combination of SMA and ECC or conventional concrete were constructed and subjected to quasi-static cyclic tests. The first column (RSC) utilized conventional concrete and steel reinforcement, the other two (RNC and RNE) utilized engineered cementitious composites (ECC) in the plastic hinge. The final report includes important experimental and analytical data to help develop design guidelines for improving the seismic response of bridge columns using SMA and ECC materials. / NOTE: Final rept.
