 Summary:
 The arch is one of the basic and frequently used linear structural elements. Compared to beams, the advantages of arches are shown in the dominant influence of axial pressure forces and in slight bending moments and transverse forces. The characteristics of the arch mostly depend on the span, height of the arch, transverse and longitudinal section, as well as on the selected static system. One of the most important parameters for the rational design of arches is the knowledge of the type of its thrust line. In this paper we have illustrated the dependence of the thrust line on the sag of the arch and the character of load. For this, we have used the mathematical models created in the computer program Sofistik. The aim of this work is better understanding of the importance of the thrust line and its application in the design of arches.
