摘要
采用自行组装的轴向拉伸装置成功地测得三峡三级配混凝土轴向拉伸应力变形全曲线 (试件截面尺寸为 2 5 0mm× 2 5 0mm) ,并根据实测资料进行数学拟合 ,建立了形式较为简单、参数求解方便、具有工程实用价值的数学表达式 .
The tensile performance of concrete can be reflected by the complete axial tensile stress deformation curve.In this paper, the measurement of complete stress deformation curves of axial tension of large size concrete specimen (250?mm ×250?mm) for the Three Gorges Project is performed successfully by use of a self designed tension apparatus.Then the measured curves are analyzed,and the formulae are established for practical use.
