Experimental testing of reinforced concrete and reinforced ECC flexural members subjected to various cyclic deformation histories

Seismic behavior of reinforced engineered cementitious composite members and reinforced concrete/engineered cementitious composite members: A review

“…Random ground motion during an earthquake event may result in large initial deformation pulses. To understand this effect on RECC members, Frank et al conducted cyclic loading tests on RC and RECC cantilever beams under three deformation histories—federal emergency management agency (FEMA) deformation history, and initial small pulse (2–2.5% drift) or large pulse (5.5–7% drift) followed by FEMA deformation history. The results indicated that RECC beams displayed seismic behavior superior to that of RC beams when subjected to an initial displacement pulse.…”

“…Especially for RC frames, the plastic rotation capacity of beams determines the seismic performance of structures via the seismic design principle of strong column‐weak beam. The cyclic loading tests on simplified, cantilever, or Ohno shear reinforced ECC (RECC) beams, as listed in Table , have demonstrated the superior seismic behavior. Figure shows a comparison of hysteresis curves for RC and RECC beams.…”

“…For simplicity, the abbreviation ECC is used in this paper. Moreover, extensive experimental study has demonstrated that ECC has great potential for use in structural members to improve or strengthen static mechanical behaviour and seismic behaviour . Therefore, the application of ECC at key structural positions may be an effective way to enhance the seismic performance of structures in regions of high seismic risk.…”

Compressive behavior of steel spiral confined engineered cementitious composites in circular columns

“…The cost of PVA fibers is only about 1/8 that of the polyethylene (PE) fibers and is even lower than that of steel fibers on an equal volume basis (Li et al, 2001). Various experimental studies have been conducted on the performance of structural members made of ECC Li, 2002a, 2002b;Frank et al, 2017;Fukuyama et al, 1999Fukuyama et al, , 2000Fukuyama et al, , 2006Li, 2009;Yuan et al, 2013). These experiments have demonstrated the excellent performance of ECC structural members, including excellent ductility, high energy dissipation capacity, and high damage tolerance.…”
