- Description
- The semi-interlocking masonry (SIM) has been under study and development in the Cen-tre for Infrastructure Performance and Reliability at The University of Newcastle, Australia. High displacement ductility, as well as significant earthquake energy dissipation, were observed during in-plane tests on frames with SIM infill panels. Hence, combining semi-interlocking masonry with other systems could be of interest. Confined masonry is a typical masonry system with the proven track record in many earthquake-prone re-gions. It is simple and cost effective. Any additional improvements in its earthquake performance would be welcomed. It is proposed in this paper to combine SIM with con-fined masonry to form a new earthquake-resistant system which is called confined semi-interlocking masonry (or CSIM) and investigate the structural performance of CSIM walls using numerical pushover analysis. Gradually increasing in-plane horizontal dis-placement was applied on simulated CSIM walls using a detailed micro-modeling FE approach. Results were assessed in terms of strength, cracking, and displacement. In addition, the effect of vertical pre-compression load, as the representative of the weight of walls at higher stories; together with the effect of shear toothing existence between the confining elements and the SIM panel were investigated.
