Abstract

Abstract

The field tests were conducted to investigate the failure mechanism of the masonry infill wall under blast loading.The blast loads and the displacements of the wall under shock waves were measured.And the failure modes of the wall were obtained as well as the ejection and distribution of the wall fragments.The experimental results indicate that the failure modes of the wall are dependent mainly on the amplitudes of the blast loads and the collapse of the wall is leaded by the failure of the cement linings.Based on the above tests, the separated numerical models were established by using LS－DYNA to simulate the dynamic response and the damage of the masonry infill wall under blast loading.And the spreads of the cracks in the wall under different blast loads were obtained and the charge weights corresponding to the different failure modes were confirmed.The numerical results agree quite well with the test data.The boundary conditions can obviously affect the failure modes of the wall.
