Seismic Tools Expected To Help Finger And Retrofit'Killer' Concrete Buildings

摘要

Two Applied Technology Council hazard-mitigation projects targeting nonductile concrete buildings-often referred to as "killer buildings" because many are at risk of collapse in an earthquake-are benefiting from information gathered during an Oct. 9-13 reconnaissance trip to Mexico City, less than a month after the Sept. 19 magnitude-7.1 Puebla-Morelos earthquake. The 14-person ATC trip aided in the refinement of a new building-specific methodology to identify killer buildings by predicting their collapse potential. The trip also provided two specimens for a project aimed at evaluating the accuracy of seismic retrofit standards for nonductile concrete structures.
