With a unique architecture and a very tight site, the vertical elements that transfer the gravity loads of a 26-story residential building to the foundation required several transfer elements that needed to remain elastic in case of a maximum considered event (MCE) earthquake. To allow for this, composite construction was used to maximize strength, and complex temporary works were erected, supporting the concrete cantilever system with steel columns during construction. Because of the additional lateral stiffness provided by the transfer elements, additional earthquake stresses needed to be controlled. The strategy was to maximize the lateral stiffness of the building and the energy dissipation of the coupling beams. The strategies successfully achieved the desired behavior, delivering a seismic response with low lateral interstory drift, and key transfer elements with an elastic performance and reserve strength, in case the seismic demand is greater than anticipated.
