Major elements:Core wall Serves as the major load taking element and to provide rigidity to resist deflection caused by lateral load (wind,earthquake loading) Usually formed by mechanical-lifted formwork system such as climb form or jump form Connection provision such as anchor plate for steel beams,build-in bar couplers or starter bar box for slab,and anchor frame for outrigger,will be provided in the core wall during its construction Major elements: Core wall • Serves as the major load taking element and to provide rigidity to resist deflection caused by lateral load (wind, earthquake loading) • Usually formed by mechanical-lifted formwork system such as climb form or jump form • Connection provision such as anchor plate for steel beams, build-in bar couplers or starter bar box for slab, and anchor frame for outrigger, will be provided in the core wall during its construction
