The invention provides a body in white bend resistance structure and an arrangement mode thereof. The lower end of a lower vertical plate of a column A is in overlap connection with a sill strip. The upper end of the lower vertical plate of the column A is in overlap connection with an outer plate of the column A. The outer plate of the column A is in overlap connection with an upper beam of a column B. The upper end of an outer plate of the column B is in overlap connection with the upper beam of the column B. The lower end of the outer plate of the column B is in overlap connection with the sill strip. Two to three layers of spot welding connection is formed at each overlap joint to form a closed structure. The bend resistance section of the sill strip, the bend resistance section of the vertical plate of the column A, the bend resistance section of the outer plate of the column A and the bend resistance section of the upper beam of the column B are each in a closed annular shape. Due to the fact that the bend resistance sections form the closed annular shapes and are composed of three or four sheet metal parts, the bend resistance is improved; due to extending sections at the upper and lower ends of the outer plate of the column B, the overlap connection efficiency of the upper beam and the sill strip of the column B and the outer plate of the column B is enhanced, and the bend resistance performance is improved; the transverse and longitudinal staggered closed structure has the effect of enhancing inertia torque, and the bend resistance performance is improved.
