This section begins with the process of defining eccentricity for purlins. The presenter selects a purlin and a truss to visualize and correctly parameterize the eccentricity. The local coordinate system's Z-axis direction is crucial for proper placement, as the purlin needs to be above the truss.
The presenter demonstrates how to set the eccentricity for the purlin by instructing the software to place it above the selected truss, considering the Z-axis direction. This parameterization is then applied to all purlins in the project, ensuring they are correctly positioned.
To ensure the eccentricity is visible in the software, the presenter shows how to activate the eccentricity display option in the model attributes. If this option is not enabled, the eccentric bars will not be shown, even if correctly parameterized.
The video then moves on to setting the eccentricity for girts on the posts. Since girts and posts have different cross-sections, a separate parameterization is required. The presenter selects a girt and a post, activates the local coordinate system display, and defines the eccentricity to place the girts outside the posts.
The defined girt eccentricity is then generalized to all girts in the project. This involves selecting all girts and applying the previously set eccentricity to ensure they are correctly positioned on the exterior of the posts.
The final eccentricity setting is for the gable purlins. Similar to the previous steps, a gable purlin and a post are selected, and the local coordinate system is used to define the correct placement. The eccentricity is then applied to all gable purlins.
After applying all eccentricities, a calculation is performed to verify the structure. The presenter checks the bar colors and types to ensure there are no errors, concluding the eccentricity modeling phase and preparing for the next step in the project.
