Seismic isolator SIP-ADAPTIVE

ADAPTIVE SLIDING ISOLATION PENDULUM (SIP-ADAPTIVE) Minimizing structural peak absolute acceleration at reduced isolator’s displacement capacity and with tuneable minimum base shear. The MAURER Adaptive Sliding Isolation Pendulum (SIP-Adaptive) represents a new type of an adaptive double curved surface slider with articulated slider. Basically, the effective radius and friction coefficient of the dry sliding surface are designed for maximum structural isolation at the ground shaking level of the Design Basis Earthquake while the lubricated sliding surface is designed to ensure high structural isolation even at very low ground shaking level. As the dynamics of the MAURER SIP-Adaptive are complex and non-linear the optimal design of both sliding surfaces in terms of effective radii and friction coefficient is obtained by model-based nonlinear dynamic simulation. This engineering service is provided by MAURER.
