The molded polystyrene wallboard with steel skeleton is composed of cold-formed thin-walled steel skeleton, flame-retardant polystyrene particles a special adhesive. The cold-formed thin-walled steel lattice columns with battens were tested under axial compression and eccentric compression. The results show that it is reasonable to calculate the ultimate vertical bearing capacity of the specimen by comparing the experimental results with the theoretical calculation results. It is found that the axial compression bearing capacity of two battens in the middle of the column along the height direction is greater than that of one batten in the middle, and the axial compression bearing capacity is increased by about 13%, and with the increase of eccentric distance around the weak axis, the ultimate bearing capacity decreases, and the specimen is more easier to buckling and in unstable.
