Abstract:After a short survey on the development of static load tests on structures, the standard test procedure used by the Swiss Federal Laboratories for Materials Testing and Research (EMPA) is presented . From the static load tests basically the following results can be gained: the elastic behavior of a structure under the applied loads as asign for the good quality of the execution the accordance of the measured deformations withthose obtained independently on a theoretic always a sign for the good quality of the design the measured spring constant of a bridge offers the possibility to qualify the bending stiffness. This qualification is based on the results of some 330 static load testing facilities.To illustrate this, three different case histories are descreibed and discussed in this paper.
