3.1 Overview The proposed equations in the AISC Guide (Murray et al. 1997) for the effective moment of inertia of a steel joist-concrete slab system, Equations (1.7) and (1.8), are based on research from Kitterman (1994) and Band (1996), and a theoretical derivation. The modeling techniques developed in Chapter 2 were used to verify the validity of Equation (1.7) as described in the following s...

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...

abstract this work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (dss). dss sintered composites of different volume percent (% vol) of partially stabilized zirconia (psz) was developed using powder metallurgy (pm) technique. electrochemical behaviour was studied at room temperature, using open circuit potential and potentiodynamic ...

Collapse of roof could cause severe economic loss and poses safety risk to residents in the building. This paper presents a nonlinear dynamic analysis of steel framed roof structures with force limiting devices under combined static and transient wind loading. Two types of force limiting devices – one with selfcentering behavior and the other exhibiting bilinear-like hysteresis are examined for...

Creep response of a full-scale floor system fabricated with composite wood I-joists and oriented strand board (OSB sheathing) was measured for 280 days at sustained uniform loads of 20 psf (0.96 kPa). Creep responses of bare I-joists and 3-joist T-beams with OSB sheathing (glued and unglued tongue and groove sheathing joints) were measured under similar load levels and duration. The creep defle...
