Due to having no software maintenance mechanism, UT Bridge is no longer available from TXDOT and UT Austin. R) used for estimating peak flow is the same as that for determining rainfall intensity (i.e., a 50 year storm is assumed to produce a 50 year peak flow). Since November 9, 2005, 24-hour precipitation gage maps for the entire CNRFC area, northern California, southern California, and Nevada are being archived and available for retrieval. The flexural design feature computes the required number and pattern of prestressing strands and the minimum required release and final concrete strengths.
