Abstract：In order to investigate the failure pattern and threshold value of masonry wall under the blast shock vibration loads, according to the practical masonry wall in the engineering the simplified masonry wall models were established, the experiments under the load of three direction separately shock were carried on using shock testing machine for simulating blast, the masonry wall models’dynamic response in action of shock vibration and the peak values、operation time of acceleration at the moment of failure were investigated. The results show that, for the bottom fixed and all-around unconfined masonry wall models, under the load of horizontal shock the failure of models displayed horizontal straight joint failure, the failure was mainly caused by tensile stress, not by shearing stress. The failure threshold value under the load of three direction separately shock was obtained by analysis on experimental results.
