Background of the new provisions for seismic assessment of masonry buildings under Urban Renewal Law is presented. First the in-situ material strength values obtained from field tests are summarized. Afterwards, the proposed stiffness approach for modeling walls as equivalent columns is described and results of the validation studies are presented. The proposed seismic assessment approach, described herein, relies on i-conducting linear elastic analysis, ii-estimation of wall strength from three failure modes and iii-comparison of demand capacity ratios with the proposed limits. The out of plane capacity check based on the wall slenderness ratio and axial stress limit are described. The assessment method is validated by using the result of pushover analysis for 10 actual masonry buildings, two of which were tested on site up to near collapse. Based on the analysis results, it was found that the limit for the ratio of shear force of vulnerable walls to the total base shear force can safely be taken as 35%.
