Recommendations for proof load testing of reinforced concrete slab bridges - presentation

842 views

Published on

Proof loading of existing bridges is an option to study the capacity when crucial information about
the structure is lacking. To define the loading criteria for proof load testing, a review of the
literature has been made, finite element models of existing viaducts have been made, and on
these viaducts, proof loading tests have been carried out. These bridges were heavily
instrumented, to learn as much as possible about the structural behaviour during proof loading.
Additional laboratory experiments have been used to develop controlled loading protocols, and to
identify which stop criteria can be used for which case. As a result of the analysis and experiments,
recommendations are given for proof loading of bridges with respect to the required maximum
load and the stop criteria. These recommendations have resulted in a guideline for proof loading
of existing reinforced concrete slab bridges for The Netherlands.

  2. 2. IABSE SYMPOSIUM ENGINEERING THE FUTURE SEPTEMBER 21-23, 2017 INTRODUCTION • Proof load testing: demonstrate that bridge fulfils code requirements for live loads • Stop criteria: no damage during test
  3. 3. IABSE SYMPOSIUM ENGINEERING THE FUTURE SEPTEMBER 21-23, 2017 OBJECTIVES • Develop guideline for proof load testing of existing bridges for the Netherlands • Stop criteria for flexure + shear • + cracked bridges
  4. 4. IABSE SYMPOSIUM ENGINEERING THE FUTURE SEPTEMBER 21-23, 2017 CONCLUSIONS • Target proof load based on equivalent sectional moment or shear • Cyclic loading protocol • Proposal for stop criteria
