Sustainable timber retrofit of concrete buildings
ERIES-STRONG
Dataset Description
This dataset comprises data and metadata from the tests performed on timber retrofit of concrete buildings. The experimental campaign involves testing two full-scale, two-story, two-bay RC frame
specimens from the elastic range up to ultimate conditions, under an earthquake-like force pattern. One specimen (S1) represents the as-built (unreinforced) configuration, while the second specimen (S2) corresponds to the retrofitted configuration. The geometry and material properties of the RC elements
remain identical in both configurations, ensuring that the only difference between S1 and S2 lies in the retrofit intervention itself.
A ReadMe file is provided to provide info on the testing plan and to explain the structure of the metadata/data provided.
Specimens Description File
Specimens
1. S1 - As-built
2
The as-built specimen (S1) was designed to represent mid-20th-century Mediterranean
RC buildings. Information on specimen geometry and member sizes, drawings regarding the reinforcement and photos are provided.
zip
1. Free-vibration
A free-vibration test was performed for information regarding the initial dynamic properties of the specimen.
zip
Instrumentation
Information on the type/position of the sensors employed and direction of measurements is provided in the accompanying files
2. Cyclic test - two phases
The test under cyclic displacement history for each specimen was executed in
two stages, as explained next:
(a) Stage 1: a pair of actuators (in a master-slave mode) applied the pre-
defined cyclic displacement pattern to the 2nd story, while a second pair of
actuators applied to the 1st story. half the total force measured at the top
storey,
(b) Stage 2: The same displacement loading pattern was applied to both 1st
and 2nd story.
The instrumentation scheme (common to both rounds of testing) is provided in the accompanying files.

2. S2 - Retrofitted
2
The specimen comprised an identical to the as-built frame which was retrofitted: the intervention involved the substitution of the external leaf of (solid brick) masonry by a cross-laminated-timber panel. A timber sub-frame was first constructed on which the CLT panel was attached. Tests on this specimen included a free-vibration test as well as cyclic loading to failure..
Similarly to S1, the test evolved in two phases:
(1) Stage 1: same as in Stage 1 of Specimen 1, but only up to 0.5% top drift
ratio.
(2). Stage 2: same as in Stage 1, but test continued up to 2% top drift ratio.
zip
1. Free vibration
A free vibration test for determoining the dynamic characteristics of the specimen, was performed.

Instrumentation
Information on the type / position of the sensors employed and direction of measurements is provided.
2. Cyclic test to failure - two phases
The specimen was subjected to a seismic-like loading pattern, comprising cycles of imposed displacement at the top while maintaining a triangular force distribution pattern along height. Photos of the specimen during preparation as well as before/after test, are presented
