The traditional practice for the design of elastomeric butt joint seals in pavement and building expansion joints is based largely on standard tests of model seals. The practice, however, does not incorporate structural analysis and does not utilize mechanical properties of the sealant. The authors of this paper study the applicability of a particular load versus deflection equation for the extension and compression design of these seals. Using experiments to measure strain energy density function for two sealants, the study demonstrates by application of these functions in finite-element analyses and by comparison of the finite-element and elementary analysis results, the capabilities and limitations of the load versus deflection equation. The authors introduce an efficient experimental procedure for assessing coefficients of the Rivlin strain energy density polynomial for general application to the analysis of elastomeric structures, and illustrate the utility of the finite-element-based approach for extension and compression analysis of butt joint seals.
