钢筋混凝土双向压弯剪扭构件抗扭性能的试验研究

Tentative study on R.C. members subjected to biaxial eccentric compression shear and torsion

根据七个构件的试验结果，研究了钢筋混凝土双向压弯剪扭构件的开裂扭矩、延性和极限扭矩等性能随轴压比和相对偏心距变化而变化的规律，并将试验结果和理论公式作了对比，符合较好．

Based on the test results of seven reinforced concrete specimens subjected to biaxial eccentric compression, shear and torsion, the failure modes and the varying laws of cracking torque, ductility and ultimate torsional strength with the change of axial stress level σ/f c  and the relative eccentricity e 0/h 0 are discussed. The test results and practical formula which well agree with each other are brought into comparison and the predictions of the practical formula agree well with the test results.
