Bridge design tutorial pdf

Select the W24x section from the American W shape database and click on the Add button. Select the W24x section that has been created. Select the Define button on the right and select the Circle section profile. Input a 2ft diameter and press the Add button.

Press the Add button. Press the Close button. Select the Cir 24 section that has been created. Select the Rect Press the Thickness button the right and input 1ft in the Node 1 input box and press the Add button. Select the newly create Plate Thickness entry in the Properties dialog box. Select all the plates using the Plates Cursor and press the Assign button. Select the Spec sub-control tab on the left.

Press the Beam button. Select the Offset tab. Select the start option from the location selection box. Select the local option from the Direction selection box. Input an offset of Select the End option from the Location selection box. Select the Local option from the Direction selection box. Assign these specifications to the steel girders parallel to the x-axis. Repeat Steps 25 to 28 for the concrete beams but use a y-offset of For Step 28, you will need to select beams parallel to the z-axis.

For the columns assign a local x-offset of 4. Click on the Add button i. Select the newly created S2 Support 2 entry and using the nodes cursor select nodes 16, 17, and Click on the Assign button. Click on the Add button on the right. Click the Close button. Select the newly created 1: Dead Load entry in the data area.

Select the Selfweight item and press the Add button. If the analysis completed successfully, you should look at the exaggerated deflected shape of the bridge under the action of selfweight. Try to find out any connectivity problems etc. You can look at the stress distribution diagram for the bridge by clicking on the Plate control tab on your left. Maximum plate stresses, moment about the local x-axis of a plate Mx , moment about the local y axis of a plate My in plate and that will be used to design for concrete deck reinforcement.

The plates are located at the center of the two spans as shown below. Maximum support reactions at the three supports which will be used to design pile cap footings using STAAD. Maximum bending moment Mz in members 65, , , , , , , , , and used to design members as per the AASHTO code. The second step is to generate the influence surface and view the influence surface diagrams. The influence surface diagram will give a clear picture of the distribution or stresses, moments, forces, etc.

To generate a deck and define a roadway, select the Plates Cursor and select all plates in the model. To accept the default name of the deck click the Ok button. The next few steps will illustrate the creation of lanes on the Deck 1 that has been created. Using the Nodes Cursor, the user may find out the coordinates of the deck as shown below. The origin of the deck is at the top left hand side corner.

The Define Roadway dialog box contains three tabs. Namely, Straight, Curved, and Custom. The meaning of the Curb A and Curb B Origin input parameters can be best understood from the above figure. The Angle input box simply allows the user to define a roadway which is placed at an angle in the Global XZ-plane.

The Curved tab is used to create a curved lane on any deck. For example, in this case, if curved lanes were desired, the engineer first has to know the center of the curve. The Angle input parameter will control the starting point of the lanes on the bridge.

The Angle is measured with respect to the line parallel to the global x axis which passes through the center of the circular lane. In the example shown in the following figure curved lanes have to be generated. Suppose the lanes are only to be generated on the region that lies between 0 and Curb A radius is 10ft and Curb B radius be ft.

The engineer needs to provide the following inputs in the Define Roadway dialog box. The Anticlockwise direction has been provided. Suppose the lanes have to be generated for the entire circular deck. The user may enter in the following inputs. The Spacing Between Points input box lets the user control the increment of the moving load on the bridge deck. In this example, there are four 10ft wide lanes. These lanes can be created using the Custom tab. Click on the Custom tab and enter the following inputs: 7.

The first lane has been created. To create the second lane click on the Add Lane to Right Button.
