Due to the demands of booming Chinese cities and increase in urban residents, safety aqueduct water transportation structures is noteworthy. A lot old aqueducts were built 1990s even earlier last century may become vulnerable potential earthquakes. This paper deals with an evaluation aqueduct’s seismic vulnerability accounting for leakage risk. Based on Hua Shigou Ningxia, a probabilistic inves...

This paper studies dynamic stability of functionally graded beams with piezoelectric layers subjected to periodic axial compressive load that is simply supported at both ends lies on a continuous elastic foundation. The Young’s modulus of beam is assumed to be graded continuously across the beam thickness. Applying the Hamilton’s principle, the governing dynamic equation is established. The eff...
