Abstract
This paper proposes a method to estimate the actual reaction loads in gimbal and hinged metal bellows expansion joints. Friction and some media pressure forces, which are not considered in current Expansion Joint Manufactures Association (EJMA) standard calculations, are added to bellows spring rate to estimate the expansion joint movement reaction moment. The proposed calculation method is based upon pressure and movement tests of large size expansion joints. [DOI: 10.1115/1.4024435] Keywords: expansion joint reaction loads, EJMA
