The document discusses the earthquake resistance of load bearing masonry structures. It notes that traditionally built masonry structures are vulnerable during earthquakes due to lack of structural integrity and proper connections between building components. Specifically, it highlights issues like inadequate wall anchorage, instability of slender walls, separation of wall wythes, and collapse of walls supporting roof structures. The document provides suggestions for improving earthquake resistance, such as introducing horizontal bands, use of ring beams, improving wall robustness. It emphasizes the importance of overall building shape and size, and proper distribution of mass and lateral loads.
