Long-term Strains in a Support Cantilever of the Chiswick-Boston Manor Viaduct M4
Acoustic strain gauges and thermocouples were placed in a reinforced concrete cantilever of the Chiswick-Boston Manot viaduct (M4) during 1964 with a view to providing information on the creep and shrinkage of a normal reinforced concrete construction. Readings have been taken over 5 years following casting. The gauges indicated a strain variation of plus or minus 0.0001 across the section during the setting of the cement. Tensile strain changes occurred on the outside of the cantilever on heating up and on the inside on cooling down. This offers an explanation for the cracking that occurs in large concrete members soon after casting. (Modified author abstract)
