Abstract

The interpretation of the load test results presented in the paper may mislead design engineers to an unconservative estimation of design loads for bridge subfoundations. Lack of error checking in the authors’ finite element analysis (FEA) model might have resulted in invalid assessment of the validity of the FB-MultiPier FEA software program.

Keywords:
FB-MultiPier, load test, I-10 Twin Bridge, finite element analysis, p-y curves
