(57) Provided in the present invention is a testing apparatus for long-term loading and synchronized measurement of concrete-filled steel tube-stiffened composite structures, the testing apparatus comprising a loading assembly, a load-measuring assembly, a deformation-measuring assembly, and a concrete-filled steel tube-stiffened composite structure. The loading assembly primarily consists of loading plates, loading rods, nuts, and pre-tightened disc springs; the load-measuring assembly consists of force sensors; the deformation-measuring assembly primarily consists of a measuring apparatus; and the concrete-filled steel tube-stiffened composite structure is a force-bearing structure. The testing apparatus for long-term loading and synchronized measurement of concrete-filled steel tube-stiffened composite structures allows for loading in stages and is capable of synchronously measuring the long-term internal forces and deformation of inner concrete-filled steel tubes and outer sleeving reinforced concrete; solves the key problem that during construction in stages, the internal forces and the deformation of the inner concrete ...
