Abstract
INFLUENCE CHARTS ARE PRESENTED FOR THE PURPOSE OF OBTAINING THEORETICAL DEFLECTIONS AND MOMENTS OF PAVEMENT SLABS UNDER LOAD. THE CHARTS ARE SIMILAR TO, AND ARE USED IN THE SAME MANNER AS, THOSE PRESENTED BY NATHAN M. NEWMARK, M. ASCE, FOR THE DETERMINATION OF THEORETICAL STRESSES AND DISPLACEMENTS IN ELASTIC FOUNDATIONS. POINTS AT A SLAB EDGE, POINTS NEAR A SLAB EDGE, AND POINTS FAR FROM ANY SLAB EDGE ARE CONSIDERED. BOTH THE ASSUMPTION OF A SUBGRADE MODULUS AS ORIGINALLY PROPOSED BY H. M. WESTERGAARD, M. ASCE AND THE ASSUMPTION OF A DEEP ELASTIC SOLID ARE CONSIDERED. THE CHARTS ARE BASED ON THE THEORETICAL EQUATIONS DERIVED BY WESTERGAARD AND A.H.A. HOGG' /AUTHOR/
