摘要

PROBLEM TO BE SOLVED: To reliably curb a construction cost without relying on experience and a skill of a designer.;SOLUTION: A design method for a building structure 1, which has columns 4 arranged at intervals respectively along an X axis and a Y axis normal to each other in a planar view and beams 5 installed between columns 4 next to each other respectively along the X axis and the Y axis, comprises the processes to: divide a floor 3 of the building structure 1 into a plurality of grids 6 which are rectangular in the planar view and respectively defined by the columns 4 positioned at four corners and the beams 5 installed between the columns 4 next to each other along the X axis and the Y axis as four sides of respective grids; calculates respective construction costs of the plurality of grids 6 with lengths Lx of the beams 5 along the X axis and the lengths Ly of the beams 5 along the Y axis varied from grid to grid by unit length; and decide the length Lx of the beam 5 along the X axis and the length Ly of the beam 5 along the Y axis on the basis of the calculated costs of the plurality of grids 6.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
