Abstract:

PILE FOUNDATIONS USUALLY FIND RESISTANCE TO LATERAL LOADS FROM (1) PASSIVE SOIL RESISTANCE ON THE FACE OF THE CAP, (2) SHEAR ON THE BASE OF THE CAP, AND (3) PASSIVE SOIL RESISTANCE AGAINST THE PILE SHAFTS. THE LATTER SOURCE IS USUALLY THE ONLY RELIABLE ONE. ANALYSIS OF THE PROBLEM YIELDS DEFLECTIONS, ROTATIONS, MOMENTS, SHEARS, AND SOIL REACTIONS AS REQUIRED FOR STRUCTURAL DESIGN. BEAM-ON-ELASTIC-FOUNDATION THEORY IS ADEQUATE FOR ANALYSIS OF THE PROBLEM. MOST PILES ARE RELATIVELY FLEXIBLE AND MAY BE ANALYZED AS THOUGH INFINITELY LONG. ONLY SHORT RIGID PILES ARE LIKELY TO REQUIRE CONSIDERATION OF THE LOWER BOUNDARY CONDITIONS IN ANALYSIS. NONDIMENSIONAL SOLUTIONS ARE AVAILABLE FOR BOTH CONSTANT AND LINEARLY INCREASING MODULUS-DEPTH RELATIONSHIPS; SOLUTIONS ARE ALSO AVAILABLE FOR A STEPPED VARIATION OF MODULS, K. SUFFICIENT EXPERIMENTAL DATA ARE NOW AVAILABLE TO ALLOW SELECTION OF THE APPROPRIATE VARIATION OF K WITH DEPTH. TYPICAL VALUES FOR K ARE AVAILABLE AND HAVE BEEN RELATED TO READILY OBSERVABLE SOIL CHARACTERISTICS. SIMPLE LATERAL LOAD TESTS ALSO ALLOW EXPERIMENTAL DETERMINATIONS OF THE MAGNITUDE OF K IF GREATER ACCURACY IS REQUIRED. /AUTHOR/
