Abstract

To calculate the target internal force of the static load test for precast beams, this paper discussed the problems such as the efficiency of static load tests, illustrated the basic principle of stress equivalence, and proposed a calculation method for determining the target internal force in the tests, with the method applied to the static load test of a precast box girder. The results show that the current regulations for load testing of highway bridges need further improvement in terms of the efficiency calculation of static load tests. Additionally, stress equivalence refers to the fact that the stress under the test load is the same as the stress under the most unfavorable stress state under a certain design load. The stress equivalence principle can be applied to the calculation of static load tests on precast beams. If there is a system transition during the subsequent construction of precast beams, the effect of the construction process on the stress of the precast beams should be considered.
