In order to improve the post-earthquake resilience of bridge structures, a Two-Stage seismic isolation method is proposed in this paper. According method, restoring force and horizontal stiffness are smaller first stage become much larger second stage. Therefore, new kind device, Friction Pendulum Bearing (TSFPB for short), invented based on traditional friction pendulum bearing (FPB short). pa...

This article proposes a novel method for analyzing residual stress and deformation in butt welding on 6 mm SUS304 stainless steel plates, using MSC.MARC, a commercial finite element method software, to find the best location for jig fixtures that will minimize welding deformation. Simulation and experimental studies show that a distance of 100 mm between the jig center and the welding bead cent...

In this study, thin layers of titanium nitride (TiN) were deposited on H13 steel substrates at different duty cycles and temperature of 520 ˚C using plasma assisted chemical vapor deposition (PACVD). Uniaxial residual stress was calculated by X-ray diffraction (XRD) and Sin2 Ψ method. Then the residual stress of the samples were measured by Grazing Incidence X-ray Diffraction (GIXRD) method and...
