Pull-out fracture of lag-screw bolt is brittle and has a large dispersion in strength. therefore, the bucking pipe preceding pull-out controls strength toughness joint. The sandwiched between bolts fixed to base plate. method little dispersion, can be controlled by adjusting thickness length effect was confirmed experiments. it also that once maximum load reached, restored exchanging pipe.

An innovative strengthening system for dapped-end beams is studied numerically and experimentally in this paper. The developed the half-joint regions of bridge also commonly called “gerber saddles”, but it can be adapted to different scenarios. consists two steel plates that are clamped on both sides webs by means bolts. purpose transfer highest possible amount shear from concrete plate element...

A detailed nonlinear finite element model was established based on completed experiments to investigate the behavior of a blind-bolted T-stub composite joint that connects beam concrete-filled square tube column. This accomplished by comparing experimental results and simulation using hysteresis curve, failure mode, plastic deformation strain development ensure reliability accuracy model. param...

The development of leakage and strength a metallic bolted flange joint are investigated in this work. Finite element analyses 2D 3D have been developed using ANSYS to study steel bolt with an aluminium gasket. pressure-penetration criterion (PPNC) has used model fluid propagation between the Validation was performed benchmark test, published joint; agreement results is excellent. Results showed...

Orthotropic steel decks (OSD's) are susceptible to fatigue failure due cyclic loading. Often cracks found in the joint between deck plate and trough. Due welding process, residual stresses present around joint. In this paper, effect of on crack propagation rate has been evaluated. First, a FE model made predict validate stress field OSD welding. The validation is comparing measured data at surf...
