ABSTRACT:
A bearing assembly for structures composed of two main elements each of which forms a portion of either the supported structure or the supporting structure or foundation. One of these main elements is formed in a "U" type shape and provided with flutings on the interior sides facing each other. The other main element is formed to fit into the interior of the other "U" type main element and is provided with flutings on opposing sides of said element. As one main element is inserted into the other, the flutings of both elements can be aligned to face each other, and complementary cores inserted. Two or more of such cores inserted at opposing sides of the inserted element, would position the inserted main element securely into the other main element, the cores filling the flutings of the "U" type main element and thus providing a secure positioning to the supported structure. To provide a certain degree of flexibility, as may be required for such structures as bridges, the cores inserted into the opposing flutings could be made from flexible material, and thus permitting for a limited movement, but nevertheless holding the supported structure securely against any upward pressure which may be caused by earthquakes or bombings.
