Project N.6
Title:
Durable seismic retrofitting
with AAM-TRM
Objectives
This ESR project will develop a fundamental understanding of the structural behaviour of retrofitting reinforced concrete (RC) elements (beams, columns, beam-column joints) and masonry walls subjected to simulated seismic loading. To achieve this, the following objectives are defined:
| 1) | Optimize the mix design (flowability and durability) of AAM to be used in the form of thin TRM-jackets. |
| 2) | Perform large-scale experiments on: (a) RC beams strengthened in cyclic flexure and/or shear with AAM-TRM; (b) columns confined with AAM-TRM jackets for increased deformation capacity; (c) beam-column joint sub-assemblages strengthened in cyclic shear with AAM-TRM; (d) masonry walls strengthened with AAM-TRM overlays against out-of-plane or in-plane cyclic loading. |
| 3) | Develop analytical and numerical models to describe the structural behaviour (prediction of failure modes, strength and deformation capacity) of elements tested as above. |
Validate the models with test data and use them to perform parametric studies and to develop design guidelines.
Expected Results
ESR6 will verify experimentally and analytically/numerically the effectiveness of AAM-TRM overlays as a means of seismic retrofitting RC and masonry structures for a number of basic cases (beams in flexure/shear, confined columns, joints strengthened in shear, masonry walls subjected to out-of-plane or in-plane seismic actions). This will enable the design of interventions for the seismic retrofitting of RC or masonry structures.
