<p>Joined portions (14) of plate materials to be joined (12a, 12b), which are joined with each other, are joined by a plurality of connector bolts (16a-16d). The connector bolts (16a-16d) are arranged in the direction in which a tensile load (F) is applied. The joined portions (14) of the plate materials to be joined (12a, 12b) are respectively configured of four regions (T 1 -T 4 ) that have different elastic moduluses. The elastic moduluses of the regions (T 1 -T 4 ) have the following relation: elastic modulus (E 1 )(region T 1 ) > elastic modulus (E 2 ) (region T 2 ) > elastic modulus (E 3 ) (region T 3 ) > elastic modulus (E 4 ) (region T 4 ). Since end-side bolts (36a, 36d) are disposed in the low elasticity regions (T 1 , T 4 ), loads shared by the connector bolts can be averaged.</p> |
