Experimental study of Reinforced Concrete framed shearwall with friction damping control devices

Abstract

In order thoroughly to improve the brittle failure characteristics of conventional lowrise shearwalls, this paper puts forward a new type of ductile lowrise shearwall scheme with friction damping control devices and carries out an experimental study on one piece of conventional framed lowrise shearwall and two pieces of the new type of lowrise shearwall under cyclic reversed loads. Moreover, from the basic assumption, after analysing the edge frame, wall panel and controlling forces, calculation formulae have been derived for the new type of lowrise shearwall. The calculated values given by the formulae show good agreement with the test values.
