摘要

利用微机控制电液伺服压力试验机和动态应变仪

对高强混凝土及纤维与混杂纤维增强高强混凝土进行了单轴压缩试验

根据实测的应力-应变曲线特点

计算了不同混凝土的压缩韧度指数

提出了纤维混凝土的受压本构关系方程.试验表明

纤维尤其是混杂纤维的掺入

使高强混凝土具有较高的抗压强度和韧度指数

其破坏点处的韧度指数达到了普通高强混凝土的2倍.采用的分段式本构方程能够完整而准确地反映不同混凝土受压时的应力-应变关系

根据试验结果确定了不同混凝土的本构关系方程.

Abstract

Uniaxial compression tests for high-strength concrete and hybrid fiber and fiber-reinforced high-strength concrete were conducted by using a servo-controlled pressure tester and dynamic strain gauge.According to the tested stress-strain curves

the different concrete compression toughness index were calculated

and the stress-strain equations were established.The tests showed that the fiber

in particular the introduction of hybrid fiber

enhanced the strength and toughness index to 2 times of that of common high-strength concrete.A series of sub-constitutive equations can completely and accurately described the stress-strain relation of different concretes under compression.
