Reinforced rubberized continuous deep beams under cyclic loadings

Al-Qadisiyah Journal for Engineering Sciences
Continuous deep beams (CDBs) expose usually to repeated and cyclic load by loading and unloading states and the wave of an earthquake. Adding scraped tires rubber to the concrete mix (which is researcher interesting nowadays) improve its dynamic properties besides the sustainability purposes.
