Steel fiber replacement of mild steel in prestressed concrete beams

Description: In traditional prestressed concrete beams, longitudinal prestressed tendons serve to resist bending moment and transverse mild steel bars (or stirrups) are used to carry shear forces. However, traditional prestressed concrete I-beams exhibit early-age cracking and brittle shear failure at the end zones despite the use of a high percentage of stirrups (4.2%). Moreover, producing and placing stirrups require costly labor and time. To overcome these difficulties, it is proposed to replace the stirrups in prestressed concrete beams with steel fibers.

Groundwater Availability Model: Hill Country Portion of the Trinity Aquifer of Texas

Description: "The purpose of this report is to document updates to this earlier model. We updated the model by adding the Lower Trinity Aquifer as another layer to the model, revising the spatial distribution of parameters, such as recharge and pumping, and calibrating the steady-state water level and river discharge conditions for 1980 and historical transient water level and discharge conditions for 1987 through 1997. The calibrated model can be used to predict future water level changes that may result from various projected pumping rates and/or changes in climatic conditions."
