Monitoring system and visualization of the stress-strain state for the berth construction in real time
In this work, the stress and strain of the berth construction is estimated by use of the finite element method implemented in the ANSYS software. The method claimed allows calculating and visualizing the stress-strain shape of the berth construction in real time by using the tracking sensors value of strain at certain limited number points. Considering the set of equations in the static formulation with reference on nodal displacement in the finite element method and taking into account that the current external influence can be represented by a linear combination of known loads taken with some coefficients, the resulting stress-strain state can be expressed as a linear combination of responses to these loads with the same coefficients. The use of a recalculated database of the structural response to known external loads and current information from sensors allows one to estimate and visualize the stress-strain state of the whole construction.
