An earthquake with Mw 6.5 occurred at 05:26 on December 26,2003 in Bam City, Kerman State, Iran. The epicenter was located in 29.01N and 58.26E. More than 40,000 people were killed, and about 90% of adobe and masonry structures were totally collapsed. The earthquake records observed at the center of the city by BHRC. Peak accelerations for longitudinal, transversal and vertical components were 778.2, 623.4 and 979.9 (gal), respectively. We carried out simple in situ test to examine the bonding strength of shear and separation direction by using a spring balance. From the results of simple tests, it was found that the bonding strength was very weak and that caused the severe collapse of adobe and masonry strucures
