The drawing heap tag check box is saved as the default so that these settings are used each time D-SHEET PILING is started or a new project is created. The performance of the wall should be carefully monitored to prevent permanent damage. By default, all segments of the external boundary are fixed. Since the top of this model represents the actual PZC 26 ground, we need to release the top surface. Item Properties window sheet pile manufacturers , the Chart Settings tab ruler marks this check box to display horizontal and vertical rulers. The big light mark marks this check box to use the large cross cursor instead of the small cross cursor. Lower PZC26 and PZC28 safety factors or higher material stresses can be applied to these conditions with the intention that the system should experience more than just appearance damage. The information bar marks this check box to display the information bar at the bottom of the input graph window. Go to the Displacements menu and select Free. The worst case of PZC26 should be used to indicate the maximum deviation from the normal load condition to evaluate the load in this case. Click the three parts that make up the top edge, then press the Enter key. You will see that the fixed boundary PZC 28 condition has disappeared from the top boundary. The grid marks this check box to display the grid in each input graph window.
Align the grid to mark this check box to ensure that objects automatically align the grid when they move or are placed in the drawing window. The PZC37, PZC39, and PZC41 designs should allow the system to maintain these loads without catastrophic crashes, but accepting potential significant damage requires repair or replacement. These PZC28 borders will now display rollers instead of pins. Check this check box to show the name of the soil layer in the input. Load this check box to display loading in the input graph window.
Use the steel sheet pile to specify the availability of components in the main window and the layout settings of the input diagram window. To compare normal and extreme conditions, the impact of a hurricane on a hurricane barrier will be a "normal" condition for control design, and the load of the same hurricane on the embankment retaining wall will be "extreme".
The PZC 26 and PZC 28 options are applicable only to graphical input. Grid distance can be used to set the distance between grid points. The same PZC 37 scale on the X and Y axes marks this check box to use the same scale horizontally and vertically. Identifying names. From the Boundaries menu, select Add Stage (we use phase boundaries instead of mining boundaries, because mining boundaries requires a completely closed space). Enter the following points:
The left and right edges should be fixed only in the X direction to allow vertical movement. Therefore, we will draw the bottom of the second PZC41 mining and define the vertical line of the horizontal extent of the mining. Select Restrain X from the Displacements menu, then select all parts of the left and right borders. We do not need to clearly define the bottom of the first excavation, because this coincides with the material boundary. Finally, we need to re establish the fixed PZC 39 boundary condition at the bottom corner. From the Displacement menu, select Restrain X, Y, click the bottom border and press the Enter key. Your PZC39 model should now be as follows:
The PZC 37, PZC 39 and PZC 41 options are applicable only to sheet pile walls or loaded piles. Support marks this check box to display support in the input graph window. Stabilizing safety factors. Various approaches to introducing "security factors" into the design process have been proposed; however, there is no common procedure. Level markers Check this check box to show the diving water level (right and left) and the markers for different levels. Usually, the design should include a degree of conservatism, which is consistent with the designer's experience and the reliability of the values assigned to various system parameters. Accredited in the engineering corps is the application of safety factors (strength reduction factors) to soil strength parameters (phi and c) and the use of "best estimates" for other quantities. The layer can only use this option when marking the check box identifier. Because the passive pressure calculated by the program described in Chapter 4 is unlikely to develop completely, rather than retaining the side active pressure, the current practice is to use the "effective" values given by phi and C to assess the passive pressure. Material PZC 41 color mark this check box to display every kind of soil material in different colors.
