| Abstract | Precast frames infilled wall construction has been widely used in the actual construction practice of Asia region. The reinforced concrete load bearing frame system can resist the substantial amount of impact came from the seismic ground shaking in the earthquake-prone zone if the joint connection parts can be adequately designed. It is better to resist the lateral seismic load by adding the infilled wall to the frame system than the bare frame because the wall can transfer the load from the contact area of the frame. Most of the conventional domestic housing in Thailand has been applied according to this way but the masonry infilled parts had not been considered in the design process. The infilled panel can be affected by the earthquake, resulting to different damages of the in-plane failures and out-of-plane instability. Therefore, this study approaches to the Precast frame masonry infilled wall. Since most of the past studies had been done with one bay cast-in place infilled wall experiment, this research is specially focused on two bays precast frame masonry infilled with concrete grouting joint under cyclic reversed lateral displacement. The prototype model is taken from the Thailand Research Fund (TRF) reference which is a 4-story commercial building in Thailand. The 2/3 scale down specimen was carefully built up with the similar way in the construction industry. All the joint connections were connected with lap-spliced short rebars to the main steel of both beam and column. The main focus during experiment is the middle column interaction with the two infilled walls. The experimental result stated that the lateral load resistance was adequate due to the high-strength precast frame and the infilled wall had been the most vulnerable portions in the overall structure. All three joint connections and the beam had been less prone to the lateral load. All the strain gage readings at that area showed the elastic limit. Most of the main steel location near to the joint intersection reached to the yield point. At the higher drift, the out of plane failure of wall had been found and the two inclined compression struts had been learnt from the strain field at the low displacement level. To conclude this, the expected plastic hinges did not occur since the frame is strong enough and the deep beam action cannot be profoundly observed the flexural bending. The masonry wall had been damaged in the form of diagonal cracking, shear sliding and the complete fall-out behavior in this investigation. |
