But throughout the hearing, speakers from the public castigated concrete, some holding up pictures that showed experimental concrete sections of the Coney Island Boardwalk that were cracked, chipped or covered in ice.
Asked about Mr. Bloomberg's remarks to The Wave, Vickie Karp, a spokeswoman for the parks department said: "The exact plans for rebuilding the Boardwalk are still being determined, but it is undeniable that the concrete sections of the Boardwalk held up extremely well".
In the second model, double pull-out test (DPOT), the concrete section of specimen was subjected to tensile stresses.
In the first model, single pull-out test (SPOT), the concrete section of specimen was subjected to compressive stresses.
The contribution of the concrete section to the punching shear resistance is obtained with existing models from the literature.
A comparative economical study shows that the total cost of the reinforced concrete section for the folded strip footings is less than the traditional one by about 18%.
Major variables include the concrete's strength, reinforcement spacing in the concrete section, thickness of the concrete cover, and applying the axial load in axial and/or biaxial directions.
Comparison to steel and concrete sections of similar outside diameter proved that the timber sections are the most efficient in terms of bending and compressive capacity to linear weight ratio.
A new method is proposed for the study of the failure mechanism of reinforced concrete sections of arbitrary shape in biaxial bending with axial force.
The design of reinforced concrete sections of arbitrary shape, namely with variable geometry, holes as well as with arbitrary distribution of reinforcing steel bars, is a very common task in civil engineering, reinforced concrete structures.
