TEMPERATURE EFFECT UPON THE NATURAL FREQUENCIES OF THRUSS ELEMENTS
In this paper we analyze the effect of temperature upon the natural frequencies of truss elements. Temperature changes influence the Young’s modulus in the sense that it decreases with increasing temperature, consequently structural elements frequencies decrease. However, we demonstrate in this paper that the frequency changes due to temperature in natural environment are very small and do not dramatically influence the structures dynamic behavior.
