| Abstract: | Based on BP neural network,as the seismic fortification type,fortification intensity,site type,seismic design group,height-width ratio,aspect ratio,stiffness,mass and of structure to main impact factor,as the maximum shear force ratio and the largest displacement of isolation bearing to output data,a base isolation structural initial design system is set up.After trained network by 25 training samples,it is used to test 15 test samples.It is show that accuracy is 96% by comparing test with actual design res... |
