Ultrasonic Signal Characteristics in Pre- and Post-yield Steel Structures
Ultrasonic Signal Characteristics Steel Structures
2010/3/5
The theory of acoustoelasticity has been the main concept behind most studies investigating the stress level in different structural materials. In this paper, an alternative approach for stress assess...
On the Creep Strength-Rupture Ductility Behaviour of 1.25Cr-0.5Mo Low Alloy Steel
Low Alloy Ferritic Steel Rupture Ductility Creep Strength Rupture Ductility Trough
2009/10/14
It is important to select materials having both high strength and good ductility in most engineering applications. This is also true for high temperature problems and the requirement of high creep str...
In steel construction it is often desirable for a steel member to pass through a concrete fire wall rather than being curtailed at the wall. In situations where a steel member penetrates a fire wall, ...
Performance-Based Design Examples for Steel Moment-Resisting Frames with Supplemental Damping
Performance-based Steel Moment-Resisting Frames Supplemental Damping Displacement-dependent
2009/2/20
The goal of this paper is to present a design procedure for steel moment-resisting frames with supplemental damping with performance-based design constraints. The first design example is based on a 4-...
The Effect of Detailing Steel in the CompressionRegions of Internal Supports on the Ductility ofReinforced Concrete Beams
Strengthening Ductility Reinforced concrete
2009/2/19
A clause on detailing in AS 3600 stipulates that 25 percents of the maximum steel in the span of a reinforced concrete beam has to be extended beyond the near face of each internal support. This sugge...
Evaluation of stress distribution in bolted steel anglesunder tension
Reader, Department of Civil Engineering, Bhilai Institute of Technology Visvesvaraya National Institute of Technology
2009/2/19
The stress distribution in the vicinity of connections in a bolted steel angle is non-uniform because of the coupled effects of connection eccentricity, shear lag and stress concentrations. Although, ...
Design of non-linear semi-rigid steel frameswith semi-rigid column bases
Allowable stress design Non-linear analysis Semi-rigid connections Steel design Unbraced frame
2009/2/19
This article presents an analysis and design method for steel frames with semi-rigid connections and semirigid column bases. The analysis takes into account both the non-linear behaviour of beam-to-co...
Equilibrium based evaluation of stress distribution under steel column base plates. I: verning Equations
Steel column base plate connections stress distribution equilibrium equations
2009/2/18
The present paper, being the first part of two relevant studies, deals with the evaluation of the stress distribution under steel base-plate connections, acted upon statically by axial forces and bend...
Plastic Mechanism and Elastic Analyses in the Strength Estimation of an Axially Compressed-Thin-Walled Channel Steel Section Beam
Channel section local buckling plastic mechanisms effective width moment capacity and axial-compressive strength
2009/2/18
This paper presents the study of an analytical model to estimate the strength of a thin-walled channel steel section beam subjected to axial-compressive loads. The model is based on two different meth...
Decision Tools for the Engineering of Steel Structures

2009/2/18
This paper gives an overview of currently available tools for decision making in the field of steel structures engineering. The theory of decision making in business, economics, and politics is well e...
Buckling Reliability of Deteriorating Steel Beam Ends
Buckling Reliability Deteriorating Steel Beam Ends
2009/2/18
Deterioration of steel beam ends due to deicing media is a common problem in colder climates. A primary effect of this deterioration is a reduction in the buckling capacity of the steel beam due to th...
Design aspects of steel I-girders with corrugated steel webs
steel I-girders corrugated steel webs
2009/2/17
Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web ...

2009/1/15
After the 1995 Great Hanshin Earthquake, Japanese design specification of highway bridges was revised and many piers and bearing supports have been retrofitted. Large span bridges such as arch, truss,...
Numerical Studies of a Steel Beam in a Frame Sub-assembly at Elevated Temperatures
Frame Sub-assembly Elevated Temperatures
2009/1/15
The analysis of structural members in a compartment in a steel framed building subjected to fire attack is often difficult owing to the combined complexity of the material degradation and of the actio...
