Abstract: Demands for eliminating columns and beams from high-rise multistory dwellings have led to an increase in such buildings with structural core walls. We have proposed and realized a new structure using ECC (Engineered Cementitious Composite) coupling beams, providing excellent flexural performance and excellent seismic energy absorption, between core walls.
ECC is a short fiber reinforced cement-based composite material with excellent tensile strain capability and crack control capability allowing multiple fine crack formation.
The structural requirements for the ECC coupling beam were such that no strength degradation was allowed at a member rotation angle of 4.0% under seismic load with no shear or bond splitting failures. The practical applications were realized by meeting the requirements through the structural experiments to establish the design principle.
