Designation:
NEFOREEE -
New fields of research in earthquake
engineering experimentation.
Project
Co-ordinator:
Professor R.T.
Severn, University of Bristol
Objectives:
To pursue research in
the following six areas of earthquake
engineering:
-
Controlled testing in the
non-linear range of material
behaviour.
-
The
complementarity of shaking
tables and reaction walls.
-
Reliability of qualification
tests performed on shaking
tables.
-
Sub-structuring methods on
shaking tables.
-
Multiple
support input to large
structures.
-
Continuous pseudodynamic (CPsD)
testing with substructuring.
The research
programme began on 1 December 2001. For
Tasks 1. and 2. above, a new test-piece
has been designed and constructed; the
test programme began in mid-2004. For
Task 3. above, large-scale test-pieces
have been used to explore the effect on
response of spurious rotational input
motions and their effect on the validity
of existing testing standards. For Task
4., a new control system has been
developed and proof-of-concept has been
achieved for a 1DOF system. For Task 5.,
exploratory studies have been made on
portal frames and compared with existing
design procedures. In task 6. above, the
principal achievement has been the
writing and implementation of algorithms
for non-linear CPsD with substructuring.
From these 6 Tasks, only
Task 1. and
Task 2.
were performed at LNEC.
