EXPERIMENTAL PROCEDURE FOR SLIP FACTOR DETERMINING AT CONNECTIONS WITH PRELOADED BOLTS

Experimental Study for Strength Capacity of Cold-Formed Steel Joists Connections with Consideration of Various Bolts Arrangements

With growth the construction technologies, Cold-Formed Steel, CFS, sections are widely used in ordinary steel buildings because of some advantages such as light weight, ease of installation, decrease in cost, and increase in speed of operation. Using the bolted connections for CFS joist is one of the best details for steel structures. The main objective of this study is to conduct an experiment...

Review of Experimental Procedure for Determining Liquid Flow in Microchannels

Large scatter in published experimental data has been observed with respect to classical theory. Recent data have confirmed that liquid, fully-developed, laminar flow in smooth microchannels of various cross-section is governed by the Navier-Stokes equations. However, when the dimensions of the channels are comparable with the wall roughness, surface effects become significant, as shown experim...

A Testing Procedure for Determining the Number of Factors in Approximate Factor Models with Large Datasets

The paradigm of a factor model is very appealing and has been used extensively in economic analyses. Underlying the factor model is the idea that a large number of economic variables can be adequately modelled by a small number of indicator variables. Throughout this extensive research activity on large dimensional factor models a major preoccupation has been the development of tools for determ...

Brane worlds with bolts

We construct a family of (p+3)–dimensional brane worlds in which the brane has one compact extra dimension, the bulk has two extra dimensions, and the bulk closes regularly at codimension two submanifolds known as bolts. The (p + 1)–dimensional low energy spacetime Mlow may be any Einstein space with an arbitrary cosmological constant, the value of the bulk cosmological constant is arbitrary, a...
