Bridge foundations in seismic regions are designed to withstand the plastic hinge moments
that develop at the bases of the bridge columns. In columns that are oversized for
architectural or other reasons, this approach results in excessively large foundations.
Various hinge details have been proposed to reduce the plastic moments transferred to the
foundation and thereby reduce the size and cost of the foundation. The results of an
experimental investigation of the seismic performance of bridge columns with moment …

Bridge foundations in seismic regions are usually designed to withstand the plastic hinge
moments that develop at the bases of the columns. Various hinge details have been
proposed to reduce or even eliminate the moments transferred to the foundations, and
thereby reduce the sizes and costs of the foundations. This study experimentally
investigated the behavior of column specimens incorporating different moment-reducing
hinge details. Tests were performed on reinforced concrete column specimens subjected to …
