Abstract: The behaviour of wall element in the in-filled concrete frame structure, subjected to lateral loading within the elastic limit has been investigated by testing eighteen numbers of one-third-scale model frames. The model frames were tested with and without brick and hollow block in-fills of thickness 25mm and 50mm (corresponding to 75mm and 150mm in reality) and with three wall aspect ratios, 0.5, 1.0 and 1.5. The study comprises of a series of laboratory tests. The tests results were further verified by the results obtained from available formulae. The results confirm that, within the range of aspect ratios 0.5~1.5, the incorporations of 25~50mm (75~150 in prototype) thick in-fill walls reduce the lateral deflections by 45~95%, with the associated wall-frame stiffness increase by 2~25 times. Other important results highlighting the minimum contributions of in-fills on this type of wall-frame structures had been compiled into the proposed recommendations to be included in future codes of practice (Chapter 6).
