A multiaxial inertial macroelement for bridge abutments

Countermeasures against Scour at Bridge Abutments

HUA LI. Countermeasures against Scour at Bridge Abutments (Under the direction of Dr. BRIAN D. BARKDOLL) Scour at bridge abutments can cause damage or failure of bridges and result in excessive repairs, loss of accessibility, or even death. To mitigate abutment scour, both clear-water and live-bed laboratory experiments in a compound channel were performed using parallel walls and spur dikes as...

A Trivariate Box Macroelement

Given a rectangular box which has been split into 24 tetrahedra, we show how to construct a C1 macroelement using polynomial pieces of degree 6.

Modelling granular soil to predict pressures on integral bridge abutments

Presented here is a granular soil model created to investigate the soil pressures which develop behind integral bridge abutments. The problem is introduced along with a brief summary of the fundamental behaviour, the model produced, and the initial validation. The paper looks at the initial outcome of the final validation procedure where experimental behaviour of an abutment is compared to the ...

The effect of the geometry of the scour around bridge abutments in the river bend

Every year a large number of bridges flooding in the river just when they most need them there destroy all born. Carried out. In this study, the four fulcrum forms a semi-circular, trapezoidal, rectangular edges rounded rectangle 90 degrees at 70 degrees in Sagittarius with four different discharges depth of constant scouring around the abutment in pure water were examined. For material of flum...
