“…At the level of the plate, the prestress also results in relative strain in the concrete [1], [2]. Displacement and friction between the plate and subsoil causes tensile stress, decreasing the pressure stress, caused by the prestress, towards the middle of the foundation.…”

This paper deals with prestressed foundation - soil interaction. For interaction task is used FEM model of thick slab with shear influence which is supported by structural strength modified elastic half-space. The calculation of deformations, internal forces and contact stresses in subsoil is performed iteratively by means of isoparametric element and numerical integration. The results of settlement and stress of non-prestressed/prestressed slab - subsoil interaction are compared on example.

“…A relatively small cable stayed bridge with a span length of 50.00 m has been built across the river Svratka in a small city of Zidlochovice [12], [13]. The adjacent roads left little space on the banks; therefore the deck is suspended on one side by an inclined pylon -see Figure 13.…”

The idea of prestressing, a product of the twentieth century, has announced the single most significant new direction in structural engineering of any period in history. It put into the hands of the designer an ability to control structural behavior at the same time it enabled him -or forced him -to think more deeply about the construction. Moreover, the idea of prestressing opened up new possibilities for a form that influence the general culture. To focus on that fact and to narrow the scope, this paper considers only bridges, even though prestressing has broad applications to all kinds of buildings. The idea of prestressing arose out of bridge design and its most impressive forms, from a purely engineering viewpoint, have appeared in bridges.

This chapter deals with the behaviour of an abutment pier on subsoil subjected to lood changes. The loods increase the cross-section of the river bed and change the properties of the foundation soil under the foundation. First, the soil saturates with water. Then, ine-grained particles will wash away and inally parts of the basement rock will be washed of. Finite element method has been used for the calculation of the interaction between the foundation and the subsoil. The foundation has been modelled in a 2D environment using spatial components. For the subsoil, an element with efects of an elastic foundation has been used. The stifness of the bedrock has been characterized by the C parameter. The chapter describes situations related to the collapse of the structure.
