| Abstract: | The analysis of force of slab super-structure under high temperature are studied by elasticity stability theory. The calculating formulas for critical force of whist force stability of structure under high temperature are conducted. The effects of factors such as fire temperature,section forms of members,ratio of length and thin,material character and depth of concrete cover etc on the critical force of whist force stability are studied. The problems how to apply in pratical engineering are discussed. |
