Abstract��In order to determine the neutral layer position of eccentric tension rod under the combined deformation, the specimen was applied eccentric force [p] in mechanical multifunction test bench, eccentric tension rod side walls of resistance strain gauge strain [��] values measured by the strain and strength tester, into the formula [��p]��([��1]��[��2])/2��[��m]��([��1]��[��2])/2 , [��]��[E]��[��]��[��1,2]��[p/A]��[6M/bh2]. When axial tensile stress and compressive stress by the bending moment was equal, stress on the rod was zero. The straight line througth stress zero and parallel rod-shaped section was the neutral layer position of eccentric tension rod under the combined deformation. The results show that the neutral layer position of eccentric tension rod under the combined deformation can be obtained with meeting the formula [y��][h2/12e]. The position of the neutral layer under eccentric tension rod related to square of [h] ( the width of the rod) and [e] ( the size of the eccentricity), had nothing to do with [b] (the thickness of rod ) and [P] (the applied load).
