as one of the methods of structural analysis, the direct stiffness method, also known as the matrix stiffness method, is particularly suited for computer-automated analysis of complex structures including the statically indeterminate type. it is a matrix method that makes use of the members' stiffness relations for computing member forces and displacements in structures.
stiffness is the extent to which an object resists deformation in response to an applied force.. the complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is.

schmertmann method, e − log б′ was an attempt to compensate the effect of sample disturbance by adjusting the results of consolidation test, as shown in fig. 2. butterfield method is based on plotting the variation between effective stress and volume change of specimen, log (1 + e) − log б′ or ln (1 + e) − ln б′. the pre-consolidation pressure is defined as the intersection ...
