SpeedCore, a composite superstructure system composed of concrete sandwiched between steel plates, recently achieved two notable accomplishments.
Purdue University researchers completed an investigation of SpeedCore's fire performance. “They found that SpeedCore panels under simulated fire and gravity loads demonstrate excellent fire resistance, even without costly additional fire-protective coatings,” according to an American Institute of Steel Construction (AISC) news release.
“With the completion of this research, no fireproofing should be required for any SpeedCore wall as long as it is at least 18 inches thick,” said AISC vice president of engineering & research Lawrence F. Kruth, PE. SpeedCore shaved 43% off the erection time of the Rainier Square Tower in Seattle—the first building to use the system, the release says.
In another development, the New York City Department of Buildings has approved the use of SpeedCore for all five boroughs. SpeedCore will eliminate the need for the temporary braced cores typically used in New York City high-rise projects, the release says.
