Thirteen frames filled with damped infill walls(DIW)and possessed of different construcionts were designed.Moreover
behaviors of the above frames
the frame filled with conventional infill wall(CIW)and the bare frame under the monotonic-static load were simulated using software ANSYS.Based on the results
the performances of the CIW and the DIWs were studied.It′s revealed that
the DIW′s masonry element moves horizontally and the wall′s deformation focuses on the VEM layers when the surrounding frame sways.In comparison with CIW
DIW bears much smaller force and is not damaged easily.It can provide certain stiffness to the frame
but produces much weaker stiffness effect and restraint effect than CIW which makes it be able to extend the structure period
enhance the structure deformation ability and delay the structural damage.Furthermore
the influences of the wall division scheme and the VEM layer construction scheme on the DIW performance have distinct regularity.The larger division number of the masonry element and the softer of the VEM layer
the weaker the DIW strut and restraint to the frame.In practical engineering
we can regulate the stiffness contribution of the DIW by adjusting the VEM layers′material hardness or layer thickness so as to give full play of the positive role of the infill wall in providing certain lateral stiffness for the frame to satisfy the normal usage demand
solve the problem of the infill causing structural components′damage for it strutting and restraining the frame too strongly.
