Steel tubes are often used as energy dissipating devices as well as structural members. The present paper is concerned with the numerical and the experimental studies on the crushing behavior of tubes. The finite element codes for the crush analysis of one-dimensional frame-like structures and arbitrarily shaped thin-walled shell structures, which were developed according to the computational algorithm [1] with low-order elements based on the reduced integration technique are applied to standard crushing problems of steel tube members. The crush tests are also carried out in order to obtain the informations on the crushing patterns which are necessary for the finite element analysis and to verify the validity of the developed finite element codes through detailed comparisons between numerical and experimental results. The following problems have been treated in the present study: (i) circular tubes under lateral compression, (ii) square tubes under lateral compression, (iii) toroidal shells under lateral compression, (iv) circular tubes under axial compression, (v) square tubes under axial compression, (vi) circular tubes under lateral loading. Due to space limitation only the results of (ii), (v) and (vi) are briefly described here. Others are contained in Ref. [2].
