Abstract

Subassemblies and building models at reduced scale are tested on shaking table facilities. This experimental program is part of the project NIKER and constitutes the Work Package 7 (WP7): “Systemic improvement of overall seismic response”. The purpose of this WP is to define global intervention strategies through shaking table tests on both substructures and entire structures before and after intervention in order to check the performance of single elements and to characterize the seismic behaviour of whole buildings. The obtained results will also allow data for FE and analytical modelling to be obtained for both single elements and whole structures. The design and the testing protocol of both subassemblies and building models were based on the results obtained from the experimental campaigns carried out on individual vertical members (quasi-static tests), on horizontal elements (e.g. floors and roofs) and on connections between bearing elements, all these performed within the same project. The experiments summarized in this paper proved the efficiency of the investigated intervention techniques and provided fundamental data to calibrate analytical models, developed within the same project, in order to describe the seismic behaviour of historic structures both in unstrengthened and strengthened conditions. This paper provides a brief overview of the whole dynamic experimental campaign and introduces some key experimental results.
