Abstract |
This paper is a basic study to evaluate the possibility of earthquake-resistant reinforcement by reinforcing engineered cementitious compositein masonry members. In order to examine the performance according to the fiber mixing rate of the engineered cementitious composite, a test specimenwas prepared according to the formulation design, and flow ability, compressive strength, flexural strength, length change rate, and direct tensile strainwere measured. In addition, non-reinforced masonry members, masonry members reinforced with engineered cementitious composite, and masonrymembers in which glass fibers and wire mesh were separately reinforced with engineered cementitious composites were manufactured, and flexuralstrength and maximum displacement were measured. All specimens reinforced with engineered cementitious composite showed more than 16 timesthe effect of maximal strength compared to that of no reinforcement, and as a result of examining the crack shape, the energy dissipation ability wasexcellent, confirming the possibility of seismic reinforcement.
