Computations include linear elastic analysis (first-order and second-order) and eigenvalue buckling analysis for both girder erection and concrete deck placement. This real-value duration capability is a great . The FHWA released the initial version of the HY-8 program in the early 1980's. The Tc is put into the TxDOT spreadsheet for calculating Rainfall Intensity-Duration-Frequency Coefficients for Texas Counties. The HY-8 program is available at no charge to the hydraulic and transportation communities. The flexural design feature computes the required number and pattern of prestressing strands and the minimum required release and final concrete strengths. concerns, Atlas 14 IDF data should be used. ()T d e b I + = In the equation above, I represents the rainfall intensity in inches/hr, T represents the rainfall duration . HY-8 is a computerized implementation of FHWA culvert hydraulic approaches and protocols. Specification checking evaluates girders for compliance with strength, serviceability, and detailing criteria. The new tool was designed to maintain a similar interface and data structure to ensure that the revised coefficients can be inserted into existing design software (GeoPack-Drainage, WinStorm, and other drainage design tools that directly use the E, B, and D values). Prior installation of Adobe Acrobat Professional is a pre-requisite. Gionis specializes in color correction, audio sweetening, keying and layering. this likelihood, use a minimum time of concentration of 10 minutes. Tabular IDF data are available Omega EM regression equations are reliable beyond 10 sq. For a list of these changes see the PGSuper support Information Document. rainfall frequency estimates are provided for states of California, Colorado and South Dakota. The minimum duration to be used for computation EBDLKUP.xls is a spreadsheet tool in current use by the Texas Department of Transportation (TxDOT) engineers and other design engineers for estimating intensity-duration-frequency (IDF) of design rainfall by county in Texas; the tool differs from discrete-duration IDF in that it facilitates estimation for real-value durations (not discrete durations).
