Blind-Test Numerical Simulation of Shake-Table Tests on Three-Leaf Masonry Walls: An Application of Lia Block_3d

Abstract

These simulations deal with the application of LiABlock_3D, a rapid computational tool developed by the Authors [1], for limit analysis of masonry structures subjected to point live loads, seismic induced lateral loads and moving supports. The software was previously validated against several experimental tests available in the scientific literature mainly concerning small scale specimens of masonry walls subjected to lateral loads and settlement. The three-leaf masonry walls of the numerical contest will be represented as 3D assemblages of rigid blocks interacting at no-tension, frictional contact interfaces. LiABlock_3D will provide as outputs the computed collapse load and the plot of the corresponding failure mechanism.
