“…In practical design, the column section in the large thermal power plant is controlled by the limit values of axial compression ratio and their sectional dimension is usually larger, so it not only increase the structural weight but also occupy space, which effects of structure. High-strength concrete used in the frame-bent structure of large thermal power plant can decrease column section, ease weight and improve the load-bearing capacity of the structure [1][2][3][4][5][6] . Under high axial compression ratio the deformation capacity of high strength concrete column needs more experimental studies to verify.…”

In order to research feasibility of high strength concrete applied to the main factory building frame and framed bent structure of large-scale firepower plant, based on the experimental research of 6 reinforced high strength frame slender columns under frequency cyclic loading, the failure shape and hysteretic characteristics were discussed. The main results show the surface concrete shedding of columns with high axial compression ratio and low hoop rate of the column drop more serious and those of columns with low axial compression ratio and high hoop rate drop slightly; with the decrease of axial compression ratio and stirrup ratio increases, the column hysteretic curve become increasingly full; the cumulative hysteretic energy become more and more big; the absorbed earthquake energy increases; the ductility also increases accordingly; whether high or low strength concrete frame column, with the axial compression ratio increases, the ductility decreases; the ductility of ordinary concrete columns is basically linear relation; the ductility of high strength concrete frame columns decreases nonlinearly with axial compression ratio increases.

“…Previous studies have demonstrated that ECC or FRCs for beam-column joint connections, columns, beams, and shear walls result in obvious enhancements of the mechanical performance [6][7][8][9]. Zhang et al [1,10] experimentally investigated the seismic performance of beam-column joint connections constructed with polypropylene fiber reinforced engineered cementitious composite (PP-ECC).…”

“…PP-FRC is beneficial to allow the structure to remain serviceable even after a strong earthquake. Han et al [8] found polyvinyl alcohol fiber-reinforced concrete (PVA-FRC) columns exhibited better plastic deformation capacity and damage tolerance as well as better energy dissipation capacity and seismic performance than conventional RC columns. Daniel et al [12] investigated the effect of steel fiber length on scaled FRC beams subjected to cyclic loadings.…”

This work presents an experimental investigation on the seismic performance of bridge piers constructed with polypropylene fiber reinforced engineered cementitious composite (PP-ECC) at potential plastic hinge regions. Eight solid square bridge piers are tested under a combination of reversed cyclic lateral loading and constant axial vertical loading. The test variables include the reinforcement stirrup ratio (0 vol.%, 0.46 vol.%, and 0.79 vol.%), axial compression ratio (0.1 and 0.3) and height of the PP-ECC regions (0, 250, and 500 mm). Seismic performance of eight specimens is presented and interpreted, including the failure mode, hysteretic curves, loading–resistance capacity, ductility, stiffness degradation, energy dissipation, and equivalent viscous damping ratio. The material test on the PP-ECC plate specimen suggests that the PP-ECC has obvious strain-hardening behavior and multiple fine-cracking characteristics, with the tensile strength and strain capacity greater than 3.2 MPa and 2.6%, respectively. The PP-ECC material applied at the potential plastic hinge regions notably improves the seismic performance and damage tolerance of bridge piers. The influence of the aforementioned crucial parameters has also been investigated in detail. The axial compression ratio and the height of PP-ECC region have a major influence on the seismic performance of PP-ECC piers. In comparison, the stirrup ratio has a limited effect on the seismic behavior of PP-ECC piers. The experimental findings shed light on the mechanism of the PP-ECC that contributes to the seismic performance of bridge piers and provide some valuable guidance in the seismic design of PP-ECC piers.

In order to study the seismic behavior o f reactive powder concrete beam-column joints reinforced with high-strength bars, an experimental investigation was carried out. A total o f 5 reinforced reactive powder concrete exterior joint specimens (including 2 specimens with HRB600 steel bars and 3 specimens with HRB400 steel bars) were cast and tested. The seismic behavior o f 5 existing test specimens was studied, including failure mode, hysteretic behavior, deformation capacity, ductility, energy dissipation capacity, and strength and stiffness degradation. The results showed that failure modes o f reactive powder concrete beam-column joints under reversed cyclic loading are mainly flexural failure o f the beam adjacent to the joint core, shear failure o f the joint core, or combined failure o f the plastic hinge in the beam and shear in the joint core. The configuration o f HRB600 bars in reactive powder concrete beam-column joints alleviates the destruction, reduces the degradation o f strength and stiffness, lessens residual deformation, and enhances both deformation capacity and energy dissipation capacity. Stirrups in the joint core directly bear part o f the shear forces and provide confinement to the reactive powder concrete. Therefore, the utilization o f stirrups in joints can retard the development o f diagonal cracks, slow the degradation o f strength and stiffness, and enhance the bearing capacity and energy dissipation capacity o f the joint. K e yw o rd s: reactive pow der concrete, exterior beam-colum n joint, H R B 600 and H RB400 steels, seism ic behavior.
