| Abstract: | The restraint relationship between the thin-walled elements is firstly explained.The calculative method about plate assembly effect in the current Chinese Technical Code of Cold-Formed Thin-Wall Steel Structures(GB50018-2002) is then introduced.Using this code,rectangular thin-walled member under different width-thickness ratios is taken as a basic unit to calculate and compare effective section area,which helps to find out the influence on bearing capacity of rectangular thin-walled member when plate assem... |
