A DISCRETE ELEMENT METHOD OF MULTIPLE-LOADING ANALYSIS FOR TWO-WAY BRIDGE FLOOR SLABS

A PROCEDURE IS DEVELOPED FOR ANALYSIS OF TWO-WAY FLOOR SLABS SUBJECTED TO DIFFERENT CONCENTRATED LOAD PATTERNS AND CONTINOUS OVER MANY SUPPORTS. PARTITIONING METHODS ARE PRESENTED WHICH ARE SIMPLE AND DIRECT IN APPLICATION. A PARTICULAR TWO-WAY SLAB STRUCTURE PLANNED BY THE TEXAS HIGHWAY DEPARTMENT WAS CHOSEN FOR DEMONSTRATION OF RESULTS OBTAINED UTILIZING THE PROCEDURE FOR THE ANALYSIS DEVELOPED IN THE STUDY. ADDITIONAL ONE-WAY SLAB STUDIES WERE MADE AND THE RESULTS WERE COMPARED WITH OTHER METHODS OF ANALYSIS. THE ANALYSES ARE MADE BY APPLICATION OF AN INCLUDED COMPUTER PROGRAM WHICH IS BASED ON FORMULATIONS DERIVED FROM A DISCRETE-ELEMENT MODEL REPRESENTING THE SLAB. THE PROGRAM HAS THE CAPABILITY OF EFFICIENTLY SOLVING A SERIES OF LOADING PROBLEMS FOR THE SAME STRUCTURE. /AUTHOR/
