Paper Title:
Experimental Investigation of Unbonded Post-Tensioned Short-Limb Shear Wall
  Abstract

In order to improve the seismic capacity of short-limb shear wall, two kinds of unbonded post-tensioned short-limb shear wall based on unbonded post-tensioned connections were put forward: (1) direct assembly short-limb wall; (2) hybrid assembly short-limb wall. The quasi-static cycle tests of two reduced scale specimens were conducted to simulate the seismic performance of 8-story symmetric double short-limb shear walls. The test results verified the basic design concept of unbonded post-tensioned short-limb shear wall, which requires that under strong earthquake action, the main part of coupling beam remains elastic and plastic deformation focus on the connection region of limbs and coupling beams. Therefore, the new short-limb shear wall is easier to fix. The test results also show the energy dissipation capacity of hybrid assembly short-limb wall is higher than that of direct assembly short-limb wall due to deformed bar crossing the interface between limbs and coupling beams.
