A DISCRETE-ELEMENT METHOD OF ANALYSIS FOR ORTHOGONAL SLAB AND GRID BRIDGE FLOOR SYSTEMS

A METHOD IS PRESENTED FOR THE DISCRETE-ELEMENT ANALYSIS OF ISOTROPIC OR ORTHOTROPIC SLABS AND PLATES ON ELASTIC SUPPORTS. AN INTERGRAL GRID-BEAM SYSTEM CAN BE INCLUDED WHICH MAKES IT ESPECIALLY USEFUL FOR HIGHWAY BRIDGE STRUCTURES. OTHER STRUCTURES SUCH AS HIGHWAY AND AIRFIELD PAVEMENTS ON ELASTIC FOUNDATIONS, FLAT OR HAUNCHED BUILDING SLABS, TWO-WAY MAT FOUNDATIONS, STIFFENED PLATES, OR ANY GRID-TYPE SUBASSEMBLAGE OF MORE COMPLEX STRUCTURES CAN ALSO BE INVESTIGATED. THE DEVELOPED COMPUTER PROGRAM ALLOWS FOR THE FREE VARIATION OF STIFFNESSES, SUPPORTS, AND LOADS. IN- PLANE AXIAL THRUSTS, IF THEIR DISTRIBUTION IS KNOWN, ARE INCLUDED AND COUPLED WITH THE STIFFNESSES OF THE STRUCTURE. INPUTS TO THE PROGRAM MAY BE RETAINED AND USED FOR A SERIES OF PROBLEMS FOR THE CONVENIENCE OF THE USER. SEVERAL PLOTTED OUTPUT OPTIONS ARE AVAILABLE INCLUDING A THREE-DIMENSIONAL DISPLAY OF THE EXAGGERATED DEFLECTED SHAPE OF THE STRUCTURE. FOUR EXAMPLE PROBLEMS ARE PRESENTED OF A TYPICAL HIGHWAY BRIDGE. /AUTHOR/
