Miyamoto Turkey conducted a feasibility study for the use of seismic base isolation for a high-rise (30 stories, 102 m) reinforced concrete building, which was to be constructed in Istanbul. The plausibility and effectiveness of base isolated system designs with LRB (Lead Rubber Bearing) and HRB (High-Damping Rubber Bearing) were investigated by comparing them with the conventional fixed base model. The design of the structures was based on local and international codes. Cost-effectiveness of the solutions for the selected performance levels, e.g. user comfort in terms floor accelerations and displacements, were examined. In addition, the effectiveness of the base isolated system in terms of architectural benefits and marketing advantages was explored in comparison to the conventional design.
