Abstract

FE modeling of pavement joints for dynamic analysis A. Alvappillai", M. Zaman* Geofec/tmcof, *> School of Civil Engineering and Environmental Science, University of Oklahoma, Norman OK ABSTRACT A finite element (FE) algorithm is developed to analyze the dynamic response of multiple, jointed concrete pavements to moving aircraft loads. A contact element model is developed to accurately represent the dowel pavement joints based on the Lagrangian multiplier method. The accuracy of the FE algorithm developed is verified by the available experimental and analytical solutions. A parametric study is conducted to investigate the effects of various parameters on the dynamic response of pavements. INTRODUCTION The early development of pavement analysis methods is primarily based on the closed-form solutions obtained from the static analysis of infinitely long pavements. The effects of discontinuities due to joints are neglected
