CSI BRIDGE

explore project information for modeling and analysis of a 200-foot concrete box girder bridge, detailing deck width, traffic lanes, parabola design, and material choices such as peosta concrete.

Open the CSI Bridge interface and start a new file with a blank model. Explore templates, such as quick segmental suspension cables, and learn initial settings, views, and analyses.

Define the layout line to begin bridge modeling, create and customize a layout with names, coordinates, and units, and apply a straight line horizontal layout for the project.

Define the lane by creating a legal line, set positive and negative centerline offsets for two lanes with a 14-foot width, then use display options to verify them.

Adjust the background color from settings by choosing a color scheme, such as white background or BlueSky, to reduce eye strain and compare with the black background.

Navigate to the components tab, define a deck section by selecting it and creating a new definition, then copy, modify, or delete as needed.

Select the item, add new data, adjust unit and thickness, verify diagram details, and click OK to define the diaphragm.

set up parametric variation and arithmetic variation, create a left-side parametric operation with 90–100 feet and 5-foot changes, and prepare for the right-side variation in the next lecture.

Define building by selecting it in the service structure, create a new entry with user defined settings, name it, fix translation vertical and calculation along the line, then ok.

Define the foundation spring by adjusting two foundations, using the new button, and naming it; set the release type to fixed and explore the split-screen option.

define the concrete section for the abutments by selecting the concrete, choosing a rectangular section, and increasing depth by four feet, then review material modifiers and reinforcement options.

Search and modify the bridge abutment data by navigating to the substructure foundation, create a new entry, select continuous beam or spring, set a 30-foot beam length, and click ok.

Define the sections for the bents by selecting properties, naming the column and pen cap, setting the diameter to feet and depth, and clicking ok.

Modify or add a new bridge element by adding a bridgepoint, naming the bank, configuring the girder support and bank type, then adjust columns, foundation, and seismic data.

Define vehicle loads on the bridge by importing a vehicle model, create a working class for multiple vehicles, and add a load pattern for stress events.

Set up abutment properties in the bridge model, name the abutments, adjust start stations, and rotate them by minus 15 degrees to align the centerline.

Define and configure a bridge bent, assign bearing angles, and rotate members by minus 50 degrees. Set elevations to minus eight, zero, and minus fifteen, add bearings, and mark fixed.

Update the model by choosing one of three options—spine model, any object model, or solid object model—and click okay to generate and view the updated design.

Adjust parametric variations to set constants and observe changes in total depth, then extrude the model from the home tab using general options and view type.

Configure prestressed tendons in the software interface, define tendon properties and loads, adjust load types and display options, and review their evolution along the span.

Select the moving load option in the analysis software, create and name the load, add it to all elements, and configure to show displacement and reactions before running the analysis.

Run the analysis to view the deformed shapes under three loading conditions, then explore results in the analysis tab and observe how stresses shift with each condition.

Create truck movement animations by defining load patterns and vehicle parameters, run the analysis, and generate a multi-step animation with adjustable magnification and frames per second.

Learn to simulate truck traffic and bridge stress, analyze the response as trucks move, and build a multi-step animation with a magnification factor for enhanced graphics.
