l properties fiber reinforced cementitious composites remain underutilized in engineering practice. One of the main reasons for this is a lack of adequate characterization of the fiber distribution within the matrix, as well as a lack of analysis methods that would allow engineers to incorporate fiber-reinforced structural concrete elements into their design. Therefore, this research has three key objectives: 1) to computationally model a stress-strain response of high-performance fiber-reinforced cementitious composites in uniaxial tension and uniaxial compression prior to macro-crack localization, 2) to develop and perform a diagnostic strain localization analysis for high-performance fiber-reinforced cementitious composites, the results of which can characterize effects of fibers on failure precursors, and 3) to quantify the effects of aspect ratio, time/duration of pouring, and the effect of rebar placement on the fiber orientation using dynamic X-ray radiography.</font></span><br style="color:rgb(0,0,0);font-family:"Times New Roman",Times,serif;font-size:14px"><font size="4"><span style="font-family:verdana,sans-serif"> <br></span></font></div><div dir="ltr"><font size="4"><span style="font-family:verdana,sans-serif"><br></span></font><p class="MsoNormal" style="margin:0in 5.2pt 0.0001pt 0in;line-height:13.91px"><br></p><span style="font-family:arial,sans-serif"><font size="4"></font></span></div><span style="font-family:arial,sans-serif"><font size="4">Host: Satchi Venkataraman</font></span><br>
