An experimental study on the axial collapse characteristics of hat and double hat shaped section members at various velocities

Characteristics of Rectangular Section and Double Hat Section

“…In [3] presented the paper the collapsed of the lean-walled lip-channel columns is prone to unity contraction in failure analysis, which deals with the buckling of narrow thin-walled lip-channel columns, which support both ends and distribute identical compression loads. The prime role of our proposal is to question the structure of the structure in the distant posterior position and the slope associated with the moment of erection loss in the column.…”

The axial collapse characteristics of hat shaped section members in a vehicle

“…A theory about the folding width in the case of spot welded section members does not exist, therefore the folding theory about the seamless section members was applied. Considering the theoretical folding width of 22 mm in the seamless case, the spot weld pitch was chosen as 22 mm [3]. The spot welding points with diameter of 6 mm are located symmetrically in the upper and lower parts.…”

“…Researches on collapse characteristics of structural member which is utilized for strength member is conducted with numerous materials and various sectional shapes [1][2][3][4][5][6][7][8]. Many studies have been conducted to study the collapse characteristics for members with spot welded hat shaped section which is nearer to the actual section [1][2][3] and for the simplified seamless section member which made of representative * Corresponding author.…”
