Bearing Capacity Analysis of N90T20 Rack Column Under Eccentric Compression
The bearing capacity of cold-formed porous steel N90T20 rack column is studied, the eccentric positions, the spacing between holes, column thickness are discussed in details. The results obtained from this study demonstrate that when eccentric space is small, eccentric compression weaken column ulti...
