Abstract Seismic analysis of buried pipes has been one study focus during the last decades,
but the systematic seismic research of pipe connections, especially its relationship with the
connected straight pipe, is nearly blank. On the basis, the influence of pipe connections on the
joint deformations (JDs) of buried segmented pipes is analyzed in detail by considering
different parameters, namely, connection shapes, ground conditions, pipe diameters, branch
angles, seismic incident angles, and input ground motions. Moreover, an influence coefficient,
which measures the influence of pipe connections on pipe JDs, is calculated. Results show
that pipe connections can reduce the JDs of… More >
