The anti-seismic analysis of large-scale underground caverns is always a difficult issue. When explicit dynamic finite element method(FEM) is adopted to perform time history analysis towards large-scale underground caverns, the consuming time is considerable and thus lowers the efficiency of project analyzes. To enhance the solving speed of explicit dynamic FEM, the hybrid method is presented based...
The reinforcement design system for lining structures based on OpenGL is developed. Firstly, the development of 3D graphic system for displaying finite element mesh based on OpenGL is introduced. Three major dynamic foundation class libraries, namely basic math library, graphic display library and geometric kernel library, are included. The finite element mesh's display algorithm is presented. Then,...
