This paper presents a proposed uniaxial damaged plastic constitutive relation of recycled aggregate concrete (RAC) based on the experimental studies. A total five groups RAC specimens with different coarse (RCA) replacement percentages 0, 25%, 50%, 75%, and 100%, respectively, are tested under both monotonic loading cyclic loading. The effect RCA percentage is thoroughly investigated variety mechanical properties, including compressive strength, peak strain, elastic modulus. Based test...
This paper presents a numerical procedure to simulate the rocking response of self-centering walls under ground excitations. To this aim, equations motion that govern dynamic are first formulated and then solved numerically, in which three different wall structural systems considered, is, (i) including self-weight only, (ii) posttensioned tendon, (iii) both tendon dampers. Following development procedure, parametric studies carried out investigate influence variety factors on seismic The...
A novel reinforced concrete (RC) segmental coupling beam (SCB), which mainly comprises the energy dissipating (ED) segment and load bearing (LB) segment, is proposed in this paper. In order to examine its applicability engineering practice, one scaled RC coupled wall specimen with SCBs was constructed experimentally investigated under cyclic loading. The results show that both cracking yielding occurred much earlier on ED segments of compared LB segments. addition, a lot more cracks...
