Building’s s Response to Sylmar Earthquake EQ4 • Performance levels anticipated were met: – Cosmetic damage at the base of the wall – Reinforcement strains reached 2.7% – Peak roof-drift ratio was 2.1% – Residual crack widths less than 1/20 th of an inch – Negligible residual displacements (1/2 in. at the roof ) • The building slice could perhaps not be immediately “occupied” but only required minimum repairs
Data Curing & Archiving • Significant amount of data has been collected and is being reduced • All data and metadata will be archived in the <strong>NEES</strong> Data Repository and will be made available to all <strong>NEES</strong> users and researchers
