UCSD SHAKES WELD-STEEL FRAME TO DEVELOP EARTHQUAKE RESISTANT STRUCTURES

The latest dynamic test further validated the weld-free steel frame system developed at UCSD.

Engineers at the Jacobs School’s Powell Structural Research Laboratories have applied post-tensioning, a technique commonly used in the construction of concrete buildings and bridges, to create a new class of weld-free steel-framed structures. The initial test conducted in 2001 on a large-scale assembly indicated that the post-tensioned steel frames can absorb strong earthquake motions with little or no damage.

The second test on November 6, 2002 proved equally successful as principal investigator and structural engineering professor Andre Filiatrault further validated the new weld-free system. This dynamic test studied the behavior of a three-column, post-tensioned steel frame supporting a concrete slab during earthquake-like conditions. The only apparent damage occurred to the concrete slab and the sacrificial, energy dissipating bars — as expected.
