Finite Element Analysis of Beams on Two-Parameter Tensionless Foundations

  • Zhaohua Feng
Conference paper


If tensile stresses connot be transmitted across the interface between a beam and its foundation, in some regions the beam may lift off its foundation, but in other regions the beam is still in contact with its foundation. In this paper a finite element iterative approach is suggested to deal with these problems. Effects of shear stresses in the two-parameter foundation are taken into account. The numerical test shows that this iterative approach gives excellent results.
