Evaluasi Teknik, Ekonomi, Sosial dan Lingkungan Jembatan Kretek Pasca Pembangunan Sheet Pile
Abstract
One drawback of linear elastic analyses is its inability to reflect the real
behaviors of structures approaching ultimate loading conditions, since almost all
structures behave in some nonlinear manner prior reaching their limit of resistance.
The basic consideration here is that a more realistic evaluation of the strength of
structure against the failure conditions, or the factor of safety, can be archived only
by analysis that take into account various nonlinearity.
A method developed to analyzing space truss structure by combining finite
element theory andnumerical techniques. The procedure of analysis and formulations
of the nonlinear finite element techniques as follows. (1) Element stiffness is
developed by using the principal ofvirtual displacement in the incremental Lagrange
formulation, (2) simultaneous equations solved by using modified Colicky method
with skyline factorization matrix, and (3) solution of nonlinear incremental and
iterative equation were performed using generalized Displacement Control method.
A computer program implementing the analysis procedures discussed herein
has been developed, and numbers of numerical examples are considered to
demonstrate.
