Structure armor is unaffected by penetration or reduction. It's been that way since the beta. Otherwise a Kassadin with Last Whisper could backdoor a turret even with no minions for support. Nether Walk in from just outside of range, then destroy turret. End-game, he'd probably be able to solo both nexus turrets before they could kill him >.<
