Aurora Avenue Bridge: no shaking here
When we "wrap" a column to help stabilize the concrete so it won't crack in an earthquake, this is what it can look like: rebar wrapped with steel. It's easy to see how this would prevent the concrete from crumbling.
In this particular project , the SR 99 Aurora Avenue Bridge Seismic Retrofit project, we wrap the columns in rebar, steel and then a specialized fiber wrap that retains the 30's style look. ^JH
