| Abstract: | Constant yielding of U steel ribs is a key to bringing load-carrying capacity into full play.The paper gives yielding conditions and discusses the influence of pre-tension of clamps on yieldable capacity of the U-steel and change of yieldable capacity in the process of yielding. |
| Keywords: | yieldable support yielding condition pre-tension of clamp carrying capacity |
