For more than fifty years, Construction Specialties has led the way in solving challenges created by building movement. After working with industry experts and structural engineers across the country, the company is introducing a seismic innovation: DriftReady Stairs.
DriftReady Stairs’ patent-pending connectors keep stairs stable at rest, yet flexible when a building moves, accommodating seismic movement and interstory drift. Construction Specialties conducted two full-scale shake table test programs in the Earthquake Engineering Laboratory at the University of Nevada, Reno. Stairs equipped with the DriftReady connectors surpassed industry-standard interstory drift levels of 2.5 percent — reaching drift levels of up to 4.0 percent.
DriftReady Stairs also reduce the transfer of damaging force back into a structure during building movement, preventing stair connection failures. This helps to ensure safe egress for building occupants — and safe ingress for first responders — during and after a seismic event. For more information, visit csdriftready.com.
Thanks to their patent-pending connectors, DriftReady Stairs accommodate seismic movement and interstory drift. They reduce the transfer of damaging forces back into a structure during a seismic event, preventing connection failures and ensuring safe egress and ingress.
