In combination with the requirement of seismic design, the structure selection of side bunker is discussed in the 8 degree seismic intensity region with site Ⅲ. By comprehensively analyzing the performances of steel structure, it is found that steel reinforced concrete is conformable to the side bunker in a high-intensity seismic area. In the steel reinforced concrete structure, the high compressive strength and high durability of the concrete are well employed, and the shape steel is set to improve the seismic behavior of structure, avoiding the brittleness breakage of high strength concrete structure.
