Energy Dissipation in Innovative Earthquake Resistant Masonry Infill Panels Made of Semi Interlocking Bricks


Abstract eng:
This paper presents an analytical procedure for evaluation of the in-plane force-displacement characteristic and the corresponding energy dissipation of a new building system for masonry infill panels - semi interlocking masonry (SIM). SIM is a mortar-less masonry system. It utilises special methods of brick interlocking that allows relative slidin g of brick courses in-plane of a panel and prevents out-of-plane relative movement. Compared to traditional masonry, it has increased capacity to dissipate earthquake energy through friction between bricks. SIM infills are intended as passive energy dissipation devices (EDDs) for earthquake resistant structures. Vibration control properties of such devices usually are determined by prototype testing. SIM panels, however, cannot be easily tested outside of the frame. In addition, being displacement-dependent EDDs, they shall be modeled in sufficient detail to capture their force-displacement response as well as interaction with primary frame elements. While the displacement capacity of SIM panels exceeds all reasonable requirements by definition, the in-plane force-displacement characteristic, which allows evaluation of the energy dissipation, must be determined. This paper presents a required procedure and demonstrates its application on different types of SIM panels. Analytical results are compared to experimental results.
