Influence of Seismic Precautionary Intensity on Some Kind of Super High-rise Building' Structure Plan

The paper can give reference to select structural scheme of the same kind of super high-rise building (150m and 180m). Different seismic precautionary intensity (SPI) and frame-corewall structure plans are compared. SPI is from 6 to 8 degree (design basic acceleration of ground motion (DBAGM) is assumed as 0.2g, g=9.8m/s(2)). When floor height is low and inclined beams can't appear in rooms, it is essential to set inner circle columns between outer circle columns and corewall. The computations shows when SPI is low, inner circle columns between core wall and outer circle columns get few. Outer walls of core wall get thin and inner walls get few. The steel and reinforced concrete (SRC) columns below the 10 similar to 15th floor can be set to get small columns. When the length width ratio of the structural plan is small, the mass of unit area of every floor and the building cost is few.
