"Come meet Granny's chicken," Mr. Rushing said, leading the way to a shrine of sorts to his grandmother: an upturned old-time bathtub decked out in glass doorknobs and shards of old mirrors (which reflect fractured pieces of the garden as well as any visitor's face), surrounded by plastic white calla lilies and tall sticks of rebar topped with upside-down blue bottles.
They acted as a classic tour group, except instead of following a flag, their lead sherpa held a ten-foot length of quarter-inch rebar topped with a blinking LED heart.

Lay concentric circle of rebar on top of the plywood sheets.
Strikingly unlike its colonial-style neighbors, the octagonal house has a zigzag of triangular windows and a pyramid crowning its flat roof, with an asterisk of steel balls and rebars on top.

For precast connections, beam bottom longitudinal rebars were welded and only top rebars have continuity throughout the joint.
Open image in new window Fig. 13 Distribution of cover thickness of top rebar; red and blue lines represent 60 mm and 90 mm thickness, respectively.
To better understand the concrete conditions, the distribution of clear cover depths to the top rebar in the validation bridges was obtained using GPR reflection data, and the results are illustrated in Fig. 13.
It was found that the third span of JB-3N, which appeared to have the highest damage ratio, was constructed with a cover thickness over the top rebar that was much less than the design cover thickness of 90 mm.
In order to ensure the highest probability of shear failure mode, a ratio of a/d = 2.5 was set, with "a" being the distance from the concentrated load to the reaction and "d" being the distance from the center of the tensile flexural rebar to the top of the reinforced concrete beam.
