Abstract：
During processing of bent and twisted steel columns in Dalian International Conference Center project, plates are bent, twisted and formed through development of special mold for bending and twisting of plates and the forming method of pressing on single point, continuous application of pressure, decrease of pressure applying speed and gradual in-segment processing; welding sequence is optimized through trial assembly and erection and shape correction with combination of mechanical force and flame. The forming effect of bent and twisted curtain wall steel column is guaranteed by the following measures, such as lengthening of welding torch, division of flange plate and post-welded web plate is reserved at position for assembly of adjacent installation segments.
