Web2. Design of Integral Bridges Design Philosophy –Lateral Earth Pressure K* depends on: • Friction angle (Φ’) of the integral abutment fill to calculate Ko and Kp • Design movement denoted d’ d • Retained height of the abutment, denoted H • Mode of movement of the bridge towards the backfill WebDec 31, 2013 · In this study, a finite element analysis has been performed to gain insight into the interactions between integral abutments, approach fills, foundation piles and foundation soils. The finite...

Analysis of Integral Bridges by Finite Element Method

WebCurrent integral designs are often conservative and based on empirical values. This study is an analysis of an integral backwall bridge which was instrumented during construction and monitored for 2.5 years. Field instrumentation included strain gages, temperature probes and earth pressure cells.
