Effects of several bolt parameters on the bearing capacity of a composite multi-drum stone column under an earthquake

摘要

The paper presents some results of a shake-table study on the effects of several bolt parameters on the bearing capacity of a composite free-standing multi-drum stone column under an earthquake. In each test, a small-scale column with six blocks per height was exposed to different horizontal base accelerations until the column collapsed. Firstly, the effect of five different materials for the bolts were investigated on the column bearing capacity. Then, the effects of bolt length, bolt diameter and the ratio of the hole diameter to the bolt diameter on the column bearing capacity were investigated. Based on the test results, the main conclusions of the study are presented.
