Abstract This study evaluates seven flat slabs made with reinforced concrete. There are three reference slabs, one of them doesn’t present any shear reinforcement. Four have a new model reinforcement stud type, internally anchored to the flexural reinforcements. That has an additional element, called on this by name: anti-cracking pins. The main objective research is find ideal spacing between ...

In a segmental metro tunnel, it is widely observed that cracks, water leakage and other structural defects usually appear at joint section of smaller stiffness than main tunnel segment section. this study, 3D finite element analysis was conducted to simulate typical concrete explicitly using continuum elements, the performance model validated against laboratory tests available in literature. Si...

The purpose of this study was to evaluate the traction characteristics of four different stud configurations on 2-Star, third generation artificial soccer turf during cutting movements. Traction, among others, characterizes player-surface interaction and is a key for top level performance in soccer. The concept of this study involves a combination of performance, subjective-sensory and biomecha...

Flats slabs became a common solution for buildings because they are easy and fast to build. In the last few years, some building that constructed using flat slab system required strengthening column junction due either imperfections during design, construction or increase of design load in case change function. The strengthen methods against punching shear (column heads, drop panels) leave an o...

This study proposes an innovative pennon plate-headed stud of shear connectors. The proposed consists two triangular-shaped steel plates on both sides the headed stud; it is expected to increase capacity a steel-concrete composite connection. Nonlinear finite element analysis carried out using ABAQUS analyze response 54 models PPH studs. A full factorial design and variance are employed in expe...

Abstract Based on the three-stage fatigue crack growth model, a corrosion life prediction method considering coupling effect of and is proposed in this paper. In case, stress factor amplitude was claimed fatigue. Three push-out tests conditions were conducted to study failure mode studs. The propagation studs, obtained through tests, simulated FRANC 3D establish library adequate amplitude. Acco...
