Description
Technical Field
The invention belongs to the field of design of extra-high voltage direct current converter stations, and relates to an auxiliary control building structure of an extra-high voltage converter station in a high-intensity region.
Background
The auxiliary control building generally adopts a national grid +/-800 kV convertor station standard design scheme, the main body of the auxiliary control building is of a 2-layer structure, and the elevation of a roof is about 12.3 m; the whole roof of the outstanding auxiliary control building is communicated with 3 staircases of the patrol walkway of the high-end valve hall, wherein the direction perpendicular to the gable at the end of the valve hall is of a single-span frame structure, and the top elevation of the part, which is out of the roof, is about 31.50 m. Because the height of the staircase room and the elevator room which protrude out of the roof is up to 19.20m, and the staircase room and the elevator room are of single-frame structures, the structure has obvious whip effect under the action of earthquake, and does not meet the requirements of earthquake-resistant specifications on lateral rigidity, frame span of class B buildings and height-width ratio of buildings.

If a reinforced concrete frame structure is adopted, the limit value requirement of the standard interlayer displacement angle can be met only by increasing the section size of the pillars of the stairway and the elevator car to 1000 x 1000(mm) or more, and the overlarge pillar section size can seriously compress the building use area of 1-2 floors and the clearance size of the stairway and the elevator car, and meanwhile, the manufacturing cost is increased.
