| Abstract;An earthquake of magnitude MW 6.5 occurred at 05:26 on December 26, 2003 in Bam City, Kerman State, Iran. The epicenter was located at 29.01N and 58.26E. More than 26,000 people were killed, and about 90% of the adobe and masonry structures collapsed. The earthquake was recorded 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 tests to examine bonding strength in the shear and separation directions using a spring balance. From the results of these tests, it was found that bonding strength was very weak and was the cause of collapse of adobe and masonry structures. (author abst.) |
