<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 (T1-T4) that have different elastic moduluses. The elastic moduluses of the regions (T1-T4) have the following relation: elastic modulus (E1)(region T1) > elastic modulus (E2) (region T2) > elastic modulus (E3) (region T3) > elastic modulus (E4) (region T4). Since end-side bolts (36a, 36d) are disposed in the low elasticity regions (T1, T4), loads shared by the connector bolts can be averaged.</p> |
