Abstract The concept of external glass FRP composite confinement is a current process for strengthening concrete beams subjected to static loads. End anchorage composites 80 mm width and 90–130 length with different thicknesses (2.4 4.8 mm) have been fixed at the bottom bolts various diameters (6 10 mm). For this purpose, behavior strengthened bolt-end anchoring fiber polymer (BEGFPC) has analy...

Aiming at the problems of high cost, large floor area and non-disassembly traditional transmission line crossing equipment, it is particularly necessary to study apply detachable foundation with low reuse rate good environmental protection performance in equipment. Therefore, maximum load combination form obtained by studying At same time, combined characteristics overturning trend we design ar...

In this study, analytical models considering different material and geometry for ‎both single and double-lap bolted joints were reviewed for better understand how to ‎select the proper model for a particular application. The survey indicades that the ‎analytic models selected for the adhesively single or double bolted lap joints, as well ‎as T, scarf, and stepped joints, with linear material pr...

This paper deals with modeling and simulation of sparking occurrence in fastening assemblies. The principle consists to calculate in three dimensions the distributions of current density and temperature in the structure over time, and to derive some physical criteria to estimate the possibility of sparking occurrence. Simulations are performed with a Finite Volume Method in time domain and an u...

A fuzzy-logic controller supporting the manufacturing of wind turbines and the bolt tightening of their hubs has been designed. The controller embeds assembly error recognition capability and detects tightening faults like misalignment, different threads, cross threads and wrong or small nuts. According to this capability, K-nearest classifiers have been implemented to cluster the output contro...

We present Bolt, a data management system for an emerging class of applications—those that manipulate data from connected devices in the home. It abstracts this data as a stream of time-tag-value records, with arbitrary, application-defined tags. For reliable sharing among applications, some of which may be running outside the home, Bolt uses untrusted cloud storage as seamless extension of loc...

OBJECT Metallic particles contained in antihuman bombs increase the number of fatalities. The ballistics of these particles depends on the explosive that is used, the distance from the explosion, the shape of the particle projected, and the biomechanics of the injured tissue. The authors present their experience with penetrating spherical bolt injuries to the brain. METHODS The authors retros...

A three-dimensional finite element model of the joint has been developed. The model has been used to predict the stress field of the laminate in the joint area, assuming homogeneity and linear behavior of the material. The modeled geometry is a T-bolt that joins a coupon of glass fiber–epoxy and a block of steel. The results obtained from the model have been verified experimentally using both e...
