• Auto-generation of wind loads.

    I have a model of a pier wall on pile cap. When I auto-generate the WS loads, I find that the column loads are applied between the top of the pile cap and the ground surface; that is, underground. Strangely, the load is the correct value (as if the wind…

  • Questions about Wind Load Generator and some more in Leap Bridge Substructure

    Hi, Dear All, Could you please let me know how the Z is calculated in the wind load generator? How do we deal with the wind load on the crush wall which is under the column but above the footing? Also, what is the best practice to enter the buoyancy…

  • 12. Aerodynamic Admittance Function for Wind Calculation

    RM Bridge inside OpenBridge Designer can calculate or define the Aerodynamic Admittance functions for the fluctuating wind buffeting forces for different mean wind incident angles of attack, as shown in the image below. The frequency-dependent aerodynamic…

  • 11 Skew Wind on a Rectangular Column

    The Verification Example 11. Skew Wind on a Rectangular Column has the objective to verify the loading type WIND on a very simple system: a column. The structural model is of only one element with two nodes and one cross-section in a rectangular shape…

  • LRFD 8 - Wind Load Auto Generation

    When using the "Generate Default Load Combination" feature, the load combinations generated are using different factors, like : - 1.4 for WS for STR GP 3, - 0.4 for STR GP 5, - and 0.3 for SER GP 1. LRFD 8 specifies 1.0 factor for all WS regardless…

  • Leap Bridge Concrete - Wind Load on Live

    Hello, When attempting to create the load combinations I receive the following message - "Dependent loads of type WL and master loads of type WS are not equal in number. Please specify same number of two loads when cross combinations option is turned…

  • QUESTION: Does LBS not check for wind loading?

    By default wind load is not added to the Load Combinations, you will have to create and add to the desired load combination to be considered. To create a new Wind load, right clicking on Wind Load Group and selecting Add Wind Load: Then you right…
