Design for de-construction of lightweight infill wall systems

This paper discusses the design for de-construction of lightweight infill wall systems. Thepaper reports the deconstruction and reassembly processes of a sample light steel frame skeleton. Each of thesteel members in the frame skeleton was connected by screws, which were removed by a screwdriver. Theobservations and findings during the deconstruction and re-assembly processes are presented. The authorsobserved that the screws in the sample steel frame were safely removed, and the members were re-assembledwithout causing any damage. The authors compared the stiffness of the frames before and after the deconstruction and observed that there was no change in the stiffness in the frame.
