摘要

对不同锈蚀程度的钢筋混凝土圆柱进行低周反复试验

研究了不同轴压比下的钢筋锈蚀率对钢筋混凝土圆柱滞回曲线、骨架曲线、刚度、延性及耗能能力的影响;给出了试件累积耗能、屈服荷载、极限荷载、荷载最大值和位移延性系数与钢筋锈蚀率和轴压比的关系。研究表明

随着钢筋锈蚀率和轴压比的增大

试件的滞回曲线趋于干瘪

骨架曲线下降段变陡

试件的刚度、延性和耗能能力减小。

Abstract

A low-frequency cyclic horizontal loading test was conducted on circular reinforced concrete（RC） columns with different degrees of rebar corrosion.In the experiment

the seismic behavior of corroded circular RC columns under different axial loads

such as hysteresis loops

skeleton curves

stiffness

ductility and dissipating energy capacity

were studied

and the relationships between the seismic behavior

such as accumulated energy dissipation

yield load

ultimate load

maximum load

displacement ductility coefficient

and rebar corrosion extent

axial load ratio

were established.It is shown that the stiffness

ductility and energy dissipation capacity

as well as areas of hysteresis loops of corroded circular RC columns can be significantly reduced

and descending branch of skeleton curves can be steeper with the increase of rebar corrosion and axial pressure ratio.
