Abstract:The previous structural scheme and new structural scheme were compared for Haikong International Plaza. The preliminary design of the plaza was introduced, and the main results were listed. Time-history analysis and Pushover analysis were conducted, and seismic performance was studied. Shear force transfer between core-wall and framed-tube was analyzed. The triangular inclined braces were taken as transfer members, which maintain elastic under seldom occurred earthquakes, and seismic performance was enhanced.
Keywords:tall building; continuous building; preliminary design; shear transfer; triangular inclined brace transfer member
