摘要： The present invention discloses an electromagnetic multiaxial fatigue testing machine, which includes a test piece fixing platform and an electromagnet loading mechanism arranged on a frame, wherein the electromagnet loading mechanism includes a first loading device for bend loading, and a second loading device for axial and torsional loading. The first loading device includes a first permanent magnet and a first electromagnet with a direction of a magnetic force generated therebetween is orthogonal to an axial direction of a test piece; the second loading device includes a second permanent magnet and a second electromagnet mounted on a swinging pair with a direction of a magnetic force generated therebetween is parallel to the axial direction of the test piece. An electromagnet principle is adopted in the invention for loading, which does not cause mechanical frictions, and different loading modes can be selected according to the actual stress requirements to conduct a uniaxial or multiaxial fatigue test on the test piece, so that the testing efficiency is improved, and the testing noise and testing cost are reduced.

摘要： The invention discloses a segment-assembled type pier column member with a steel-concrete composite structure, which includes a reinforcement tube embedded in a pile cap, wherein the reinforcement tube is connected with a bottom of a lower segment of a hollow steel tube pier and is poured with concrete, and pier columns in upper and lower segments are reinforced by means of segment connecting and being embedded with local reinforcing meshes. A steel cross beam is connected with an upper segment of the hollow steel tube pier in an assembled way. A pre-stressed tensioning duct is reserved between the steel cross beam and the pier column in the upper segment. According to the present invention, a construction period and construction difficulty are reduced, a construction progress is accelerated, the connecting method is safe and reliable, and is convenient to control by adopting an assembled construction method; meanwhile, good concrete compression performance and good steel tensile property are sufficiently utilized, so that the whole member is economic and convenient, is simple and fast to construct, and has a good application prospect.
