Earthquake-prone zones require structural systems that can absorb seismic energy rather than rigidly resisting it. During the seismic retrofit of a multi-story apartment building in Tokyo, structural engineers integrated the EPS Cement Sandwich Panel to reduce overall dead load and enhance structural flexibility.
Heavy buildings suffer greater inertial forces during an earthquake. By replacing heavy brick infill walls with the lightweight EPS Cement Sandwich Panel, engineers reduced the building’s total seismic weight by nearly 35%.
Furthermore, the interlocking panel system demonstrated excellent ductility and crack resistance under lateral stress testing. The panels flexed slightly with the steel framework without collapsing or shedding heavy debris. Residents gained a safer, lighter, and structurally sound home, reaffirming that the EPS Cement Sandwich Panel provides essential earthquake protection in high-risk zones.
