Simulation of blind pre-diction and post-diction shaking table tests on a masonry building aggregate using a continuum modelling approach

Abstract Masonry buildings of historical centres are usually organized within aggregates, whose structural performance against seismic actions is challenging to predict and constitutes still an open issue. The SERA—AIMS (Seismic Testing Adjacent Interacting Structures) project was developed provide additional experimental data by testing a half-scale, two-unit stone masonry aggregate subjected two horizontal components dynamic excitation. In this context, paper investigates the reliability modelling approach assumptions adopted generate three-dimensional continuum finite element model. work involves stages, namely blind pre-diction post-diction phase, proposes series simulation analyses including strategy shorten actual records save computation costs. study performed investigate extent uncertainty in for such aggregates relation outcomes. Pre-diction results were proven be not accurate terms predicted displacements damage patterns. upgrades introduced analyses, calibration elastic modulus introduction non-linear interface between units, allowed improve outcomes, with reasonable base shear force, along Y-direction pattern stage. overall showed appropriate analysis existing but type structure remains due high level uncertainties.
