The concrete tester has the advantages that the complete stress-strained full curve can be obtained; the strain rate of tested pieces can be controlled, and the pulling-pressing stress-strained full curve in different strain rates can be measured; the change of the strain rate in the testing ...

compressive stress-strain curveThe strength and deformation capacity of concrete will deteriorate due to theerrosive materials in the environment,such as salts,acid,and microorganism. Uniaxialcompression tests were made to develop the stress-strain model for the corroding concrete.According to the ...
The stress–strain characteristic of concrete developed in flexure is one of the essential parameters for the ultimate flexural strength design of reinforced concrete (RC) members. Currently, the stress–strain curve of concrete developed in flexure is obtained by scaling down the uniaxial stress–stra...
A complete stress-strain curve model for concrete confined by rectilinear reinforcement was proposed. In this model, the confinement effect of rectilinear steel, including common hoops and square steel tube, was evaluated by using effective lateral pressure factor. Major variables influential in the con...

(5), (6). For the softening descending branch, a power function is used with the condition that the stress strain curve passes through a point on the Conclusion A review of the confined stress strain model of Attard and Setunge [22], revealed that despite its wide usage, the model is ...
The analytic expression has four constants which depend on the properties of both the ascending and the descending portions of the stress-strain curve and can be evaluated from the knowledge of four key points of the curve. The coordinates of the four key points were expressed in function of ...
