In the face of building movement, occupant safety becomes the highest priority. CS has designed, developed and tested solutions to reduce and eliminate the unintended consequences conventional stair systems impose to structures during a seismic event, such as:
DriftReady Stairs move with the building, so instead of acting like a brace and transferring damaging forces back to the building, the system flexes and accommodates the movement without impacting the stair connection or the surrounding structure.
We conducted full-scale shake table tests in the Earthquake Engineering Lab at the University of Nevada, Reno. In one test, we examined several conceptual methods for accommodating MCE movements. In another, we measured the performance of some existing solutions as well as our own refined solutions. A few of the configurations tested can be viewed below.
