Tests of Large-Scale Structures/Members

JFE-TEC has abundant experience in structural testing using a diverse range of testing machines and devices, and also has extensive experience in model tests and experiments in outdoor environments. We evaluate the performance of structures from the member level to the actual scale of structures by static/dynamic tests, fatigue tests, FEM analysis, etc. We provide solutions ranging from proposal of experimental plans and preparation of test specimens to comparison/evaluation of test results with numerical analysis.
