1. CandeCAD Overview UTILITY Step 1: MESH DESIGN Step 2: ASSIGN INTELLIGENCE Step 3: CONDUCT ANALYSIS Step 4: IMPORT RESULTS

2. Step 1 MESH DESIGN

3. INSERT NODES INSERT ELEMENTS Insert a node at a time Insert nodes on construction grid Bind nodes together Turn circle/spline into polyline Insert a beam-column element Insert beam-column elements Insert a interface element Insert an element Insert elements on a construction Grid Insert increasing elements Automatically insert elements Merge with triangular elements Remove redundant diagonal Step 1 MESH DESIGN Sub-Commands

4. Assign Intelligence Assign pipe/culvert model Assign soil/material model Assign interface element model Assign construction increments Apply nodal forces Apply distributed loads View by construction increment View a construction increment at a time View by material zone Reset to input graphics Step 2 ASSIGN INTELLIGENCE

5. Step 3 CONDUCT ANALYSIS

6. Import Results Import existing Level 2 case View output file Import results for a construction increment Import results for all construction increments Display displacement from undeformed position Display bending moment in pipe wall per unit length Display circumferential thrust in pipe wall per unit length Display shear force acting on pipe per unit length Display normal pressure acting on pipe periphery Display shear traction acting on pipe periphery Step 4 IMPORT RESULTS (1 of 2)

7. Step 4 IMPORT RESULTS (2 of 2) Import Results Display soil stress in x-direction Display soil stress in y-direction Display soil shear stress in xy-plane Display soil strain in x-direction Display soil strain in y-direction Display soil shear strain in xy-plane Display failed soil elements Select construction increment number Measure Results Display legends

8. Utility Find an element Find a node Toggle node Crossing polygon View by construction increment View by material zone Reset to input graphics Master control CandeCAD help Toggle construction layer UTILITY Number elements
