Abstract

A column is a structural member that bears an axial compressive load and is more likely to fail due to buckling compared to material strength. Some of these columns work at a high temperature and this temperature affects the behavior of buckling. Therefore, the designer must take this factor (temperature) into consideration. For the purpose of studying the effect of different temperatures on the phenomenon of buckling under compression dynamic loads to evaluate the state of failure for different types of columns, the thermal buckling test device has been designed and manufactured. Using this rig, practical tests can be conducted on solid and hollow columns of different metals and diameters, and thus the safe critical load for the column can be predicted. This device was successful in evaluating the life of the columns made of aluminum alloy (6061-T6) when the buckling interacts with heat. The current study found that rising the temperature increases the failure under the buckling phenomenon.

Highlights

  • A thermal buckling test rig was designed and constructed under variable temperatures.
  • The buckling properties of the material used are less with increasing temperature.
  • The buckling load is reduced under the influence of interaction the load with temperature.
