Investigating Torsional Behavior of Fiber Reinforced Self Consolidating Concrete under Cyclic Loading

Researchers in the construction industry have shown great interest in rheological and mechanical properties as well as durability of fiber reinforced self-compacting concrete (FRSCC), however, its behavior under torsional cyclic loading, has rarely been studied. In the present experimental research,...
