EXPERIMENTAL-STUDY OF REINFORCED-CONCRETE FRAMED SHEARWALL WITH FRICTION DAMPING CONTROL DEVICES

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 device s and carries out an experimental study on one piece of conventional f ramed lowrise shearwall and two pieces of the new type of lowrise shea rwall under cyclic reversed loads. Moreover, from the basic assumption , after analysing the edge frame, wall panel and controlling forces, c alculation formulae have been derived for the new type of lowrise shea rwall. The calculated values given by the formulae show good agreement with the test values.
