This thesis is based on October 8, 2005 7.6-level earthquake reconstruction in the Pakistan disaster areas. Pakistan Earthquake Bureau designed the architectural standard as the background of the China-Pakistan cooperation project, and a sub-project under the standard is discussed in this thesis. Ordinary sintering brick and stone-dust mortar masonry are set as window walls of masonry walls construction, which is also the object in this thesis. Based on the quasi-static experiment, the masonry walls earthquake damage patterns and seismic behavior are studied, underlining Pakistan formulation of the unified national standards for architectural design with basic data.
