In this paper, we make connection between CFT$_3$ three point correlation function of conserved currents and 4D amplitude general spin massless gauge field explicit. We do so by taking flat space limit momentum CFT show how they reproduce amplitudes. then out a mismatch number independent structures in 3D correlator covariant vertex higher fields. This is contrast with expectation that counting...

To investigate the seismic behavior of end-plate connection semi-rigid space steel frames, three 1/4-scale specimens were tested under cyclic load. Finite element analysis which took initial geometric imperfections into consideration was also conducted, and the results conform to experimental results. The failure modes, hysteretic behavior, deformation capacity and energy-dissipation capacity o...

Abstract This research investigates the behaviour of novel U‐connector used in cold‐formed steel (CFS) truss‐to‐column connection. The novelty is reflected specially designed connector geometry and connection method within cross‐section thin‐walled C‐profile. installed inside can be exposed to tensile, compressive shearing action. shear thoroughly investigated using laboratory tests. Three diff...
