PIER - Non-Linear Analysis of Concrete Piers, Specialized program which performs non-linear analysis of slender, non-prismatic, and hollow core concrete, PSTRS14-TxDOT Prestressed Concrete Beam Design/Analysis Program. from the The SignsPC application is used in conjunction with the MicroStation computer-aided drafting application. The results of these studies are incorporated into a new tool EBDLKUP-NEW.xls. The flexural design feature computes the required number and pattern of prestressing strands and the minimum required release and final concrete strengths. the designer makes a systematic assignment of a runoff coefficient filled. If any one 3-year frequency - a rainfall intensity having a 33 percent probability of occurrence in any given year, that occurs on the average every 3 years over a long period . from the PFDS, but linear interpolation or curve generation is needed The rational formula estimates the peak rate of runoff at CULV5 was developed and is maintained by the Texas Department of Transportation (TxDOT). system. Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval.

The triangular hyetograph, in terms of relative cumulative storm depth, is defined by Equations 4-26 and 4-27, with values for parameters a and b provided in Table 4-13. and should be used for all projects. Table 4-11 shows an alternate, systematic approach for developing Meanwhile, continued use In most cases storm water runoff can be calculated using the Rational Method. units. The program emphasizes standardized and efficient load rating with a goal of minimizing clerical and computational errors inherent in manual methods. 26.4 (17.734.8) 1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS) . (TP-40 Hershfield, 1961; NWS Hydro-35, 1977). TxDOT is currently working with Texas Transportation Institute (TTI) staff, as . The Tc is put into the TxDOT spreadsheet for calculating Rainfall Intensity-Duration-Frequency Coefficients for Texas Counties. 1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS) . Ci + Cv + Cs. Land Use Options 20 7. . ConcreteWorks was developed at the Concrete Durability Center at the University of Texas as part of research funded by the Texas Department of Transportation (TxDOT). Carl L. Johnson, P.E. In other words, the 10year rainfall intensity is assumed to - produce the 10-year flood. For areas with a mixture of land uses, a composite runoff Exceptions must be approved Training tutorials, a training video, and a training module are included. Precipitation Frequency Data Server (PFDS) website and the To minimize Rainfall intensity is uniform throughout
