Name:

Step-by-step moving-load analysis first steps

Description:

Procedure for setting up step-by-step moving-load analysis.

Program:

CSiBridge

Version:

18.0.1

Model ID:

na

Step-by-step moving-load analysis can be setup using the following procedure:

  • Define Vehicle via "Loads Tab > Vehicles > New".
  • Define layout line via "Layout Tab > Layout Line > New".
  • Define lane via "Layout Tab > Lane > New".
  • Use "Load Tab > Load Patterns" to define new load pattern of type "Vehicle Live". See Figure 1 below. Use the "Modify Bridge Live Load" button to define the load assignments, such as lanes, vehicles, vehicle speed, movement direction, etc.

  • A multi-step static load case is automatically created. This load case may be reviewed via "Analysis Tab > Load Cases > Modify".
  • Dynamic response may be evaluated when load-case type is changed from Multi-step Static to Time-history, and analysis type to Nonlinear, Direct-integration. Damping and other parameters may be specified as necessary.
