TECHNICAL EXPERTISE

Structural Testing

Peter Lindsell & Associates have wide experience of full-scale and model testing of bridges and structures over a period of more than 25 years. Incremental live load tests have been applied to more than 120 bridge spans, constructed from cast iron, wrought iron, steel, reinforced and prestressed concrete. Structural instrumentation and in situ stress measurements have also been undertaken on numerous structures throughout the UK and abroad.

PROJECT EXPERIENCE

Dr Peter Lindsell, MA(Oxon), PhD, CEng, MICE, MIStructE, MIHT, MEWI, FIDE

Introduced to live load testing of bridges in 1971 following the reconstruction and strengthening of five 3-span post-tensioned segmental bridges. Initiated a research programme involving the model testing of a range of typical concrete bridge abutments to assess the benefits of 3-D behaviour from 1975-79. Subsequently, designed and installed a long-term monitoring system to record the construction effects and earth pressures acting on a pair of spill-through bridge abutments from 1981-87 on behalf of the Transport and Road Research Laboratory. Additional research grants awarded by CIRIA and SERC from 1983-89 to develop structural monitoring and in situ stress measurement techniques to assess long-term losses of prestress in post-tensioned concrete structures. Major structures tested during this period included the concrete linings of the initial sections of the Channel Tunnel and several concrete box girder decks in service and during controlled dismantling.

Joint author of research reports for Transport Research Laboratory on “Measurements of Prestress Losses” and “Additional Sources of Prestress Losses” in post-tensioned concrete bridges, based upon previous research and field studies. Undertook in situ stress measurements and structural tests on some 150 bridges and structures throughout the UK, Europe and Far East. Responsible for drafting initial research study and framework for load testing of bridges on behalf of the National Steering Group.

Dr Susanné Buchner, BSc, PhD, CEng, MICE, FIDE

Joined full-scale structural research team at Surrey University in 1983. Awarded PhD in 1989 for research monitoring of full-scale structures during demolition and in situ measurement of long-term prestress losses in existing structures. Worked in conjunction with Dr Lindsell on all structural testing projects since 1983 to present time. Joint author of research reports for TRL and National Committee on Load Testing of Bridges. Presented numerous lectures and papers on in situ stress measurements and live load testing of bridges throughout the UK.
