This paper experimentally investigates the cyclic inelastic performance of concentrically braced frames with and without cold formed steel stud ~CFSS! infills designed to laterally restrain braces and delay their buckling. Specimens have either diagonal tube or solid bar braces with and without CFSS and U brackets providing out-of-plane and in-plane buckling restraint. Behavioral characteristic...

PURPOSE This study was accomplished to assess the biomechanical state of different retaining methods of bar implant-overdenture. MATERIALS AND METHODS Two 3D finite element models were designed. The first model included implant overdenture retained by Hader-clip attachment, while the second model included two extracoronal resilient attachment (ERA) studs added distally to Hader splint bar. A ...

Using recycled aggregate concrete (RAC) in steel-reinforced structure is an effective way to eliminate the adverse effects of aggregate, which has excellent application prospect. Fire a great destructiveness (SRRAC) structure; hence, bond performance SRRAC after high temperature, as prerequisite for composite between steel and RAC, key problem structural safety corresponding assessment fire. In...

Concrete-filled steel tube (CFST) columns are frequently used in construction due to their high ductility and improved loadbearing capacities. At beam-to-CFST column joints, gusset plates welded the outer face of tube, specific elements should ensure shear transfer between inner concrete core. The current systems studs, internal rings, angles, plates, bars, tab stiffeners, etc. Although good, t...

A fabrication process has been developed for fully planarized Nb-based superconducting inter-layer connections (vias) with minimum size down to 250 nm for superconductor very large scale integrated (VLSI) circuits with 8 and 10 superconducting layers on 200-mm wafers. Instead of single Nb wiring layers, it utilizes Nb/Al/Nb trilayers for each wiring layer to form Nb pillars (studs) providing ve...

During maintenance operations, technicians have to work as quickly as possible. But they are often stopped during disassembly by blocked bolts or studs. This paper examines causes of blockage and suggests new method for disassembling bolted joint in this case. Several methods are analyzed and tested with finite element simulations. An experimental protocol to test a new disassembling method is ...

In this study, calibrated hot box and finite element simulation methods were used to study the influence of a slotted web on thermal performance lightweight steel stud composite wall. By comparing results from simulations experiments, accuracy method was verified; then for parameter analyses. The showed that wall’s transfer coefficient is inversely proportional increases in length slot height w...
