How to use a calculated scheme correctly
As a calculated scheme, an uncertain beam was accepted on elastic settlement supports with nonlinear characteristics of rebuke.
The values of the elastic rebuff of the compresses of the steps depend on the size of the external load, the accepted cross -section of the steps, their initial tension and the magnitude of the displacement of the mast nodes under load. Only the extensive experience of the calculation allowed us to guess the correct ratio of all these factors and get a more or less acceptable result.
When developing an algorithm and compiling a program for calculating a mast of the ECVM, the basic principles of manual calculation were left uneasy and only new analytical dependencies were introduced in determining the elastic characteristics of the compulsive nodes.
