Interaction of normal and shear loads in carbon reinforced slab segments

Abstract

<p>In recent years, textile reinforced concrete (TRC) has become increasingly important in scientific research. Thin slab segments of TRC in particular show great potential for use in secondary structural systems in bridges or high-rise buildings. However, research has not yet sufficiently investigated all load combinations and some questions remain unanswered in the design process. Especially in restrained structures the interaction of moment, shear, and normal tensile forces might govern the design. To investigate this load combination, a new test setup was developed at the Institute of Structural Concrete of the RWTH Aachen University. A numerical study complements the investigation to extend the database beyond the limited range of experimentally tested parameters. According to the results, the shear resistance decreases with increasing tensile normal force, yet separation cracks have no negative influence.</p>
