Abstract A staircase provides the main escape way from a building in an emergency. Unfortunately, it may suffer severe damages or even collapse during an
earthquake. For improving the seismic performance of staircases, this paper
proposes an innovative staircase isolator with the features of lightweight, costeffective and ease of construction and replacement, which is formed by suitable
engineering plastic shims between rubber layers. A connection construction
scheme is also proposed for the isolated staircase. Systematic performance tests
have been carried out to characterize the isolator in terms of mechanic behavior
and ultimate states. The test results show that mechanical properties of… More >
