Abstract

The primary objective of this thesis is to provide accessible methods for numerical analysis of the mechanical behavior of welded structures specific to roadgoing trailers as defined by the Federal Motor Carrier Safety Administration. The area of highest interest is hot-dip galvanizing. The influence of temperature on steel has long been studied and several sources have found, or otherwise mathematical expressions were derived which describe the relationships between mechanical properties and temperature. Understanding all failure modes associated with the design of a structurally acceptable trailer goes beyond a simple static force analysis. Road going trailers undergo acceleration in the vertical, lateral, fore and aft directions sometimes in excess of three times the acceleration of gravity. Additionally, in the case of traversing uneven terrain, these loads can become cyclical and therefore, fatigue must be taken into consideration. This paper represents a proposed guideline for structural design.
