Experimental Study on Shear Behavior of Mid-rise Assembled Monolithic Concrete Shear Walls with Varying Axial Compression Ratio

Objective:

Quasi-static tests of three mid-rise assembled monolithic concrete shear walls, whose aspect ratio is 2.0, were completed in this paper. The failure mode of three new-type shear walls and the effect of axial compression ratio were studied.

Result and Conclusion:

The result showed that the brittle failure was extinct, and the new-type shear walls had good deformability whose ductility factors were over 4.3. The axial compression ratio had significant influence on the mechanical properties of the new-type shear walls. As the increscent of the axial compression ratio, the shear capacity and initial stiffness were improved, but the energy-dissipating capacity became worst.
