Ring flange connections with preloaded high strength bolts are most commonly used to connect two segments of steel tubular towers. Behaviour and durability ring is influenced by various factors, including stiffness flanges, fabrication execution imperfections, welding technology details the flange/segment connection, type bolts, pretension technique control accomplished force in bolts. This pap...

The mechanical behavior of T-stubs bolted connection with two and four bolts per row under monotonic cyclic loading is analyzed in this paper using a 3D finite element model. aim the model that takes into account material geometrical nonlinearities to obtain evolution prying forces throughout cycles loading. numerical also used compare those row. results are prepared be as basis for proposing a...

Due to the commonly eccentric connection on only one angle leg (bolted or welded), additional bending moments are acting member under compression axial force, leading a complex load-carrying behaviour with flexural and/or torsional buckling phenomena. Furthermore, type and size of rotational restraints at member's ends (provided by adjacent structure) significantly influence capacity these memb...

Mechanical fasteners especially bolting is commonly used in joining carbon-fiber reinforced polymer (CFRP) composite structures due to their good joinability and easy for maintenance characteristics. Since this approach involves with notching, a proper progressive damage model (PDM) need to be implemented and verified to capture existence of damages in the structure. A three dimensional (3D) fa...

Abstract In cross-laminated timber (CLT) buildings, in order to reduce the disturbing transmission of sound over flanking parts, special insulation layers are used between CLT walls and slabs, together with insulated angle-bracket connections. However, influence such connections on seismic resistance structures has not yet been studied. this paper, experimental investigation panels installed be...
