  • R1001.3

    Seismic Reinforcing

    • In Seismic Design Category D0 to D2, masonry or concrete chimneys are reinforced per Table R1001.1 and Section R606.

    Local review: San Antonio sites are normally Seismic Design Category A or B, so chimney reinforcing and anchorage are usually not required; confirm the SDC for the site in Table R301.2.
