The Efficiency of Reduced Beam Section Connections for Reducing Residual Drifts in Moment Resisting Frames
Residual Deformations Reduced Beam Section Connection P-Δ Effects
2013/1/31
In most framed structures anticipated deformations in accordance with current codes fall into acceptable limit states, whereas they go through substantial residual deformations in the aftermath of sev...
Transverse Vibration of a Beam Under Constant Stress
Transverse vibration Dimensionless natural frequency Isotropic material
2009/10/14
In this study, transverse vibrations of a beam made of two materials and with a variable cross section
were investigated. Dimensionless natural frequency values of the system were found by the Raylei...
An Experimental Study on the Effect of Steel Fiber Reinforced Concrete on the Behavior of the Exterior Beam-Column Joints Subjected to Reversal Cyclic Loading
Beam-column joint Steel fiber reinforced concrete Ductile behavior
2009/10/12
For the ductile behavior of beam-column joints, closely spaced transverse reinforcement is required by earthquake codes. However, placement of this reinforcement in joints always causes some dicultie...
Cyclic behaviour of plate-to-beam welded connections
Plate-beam steel strength welds cyclic
2009/9/30
Modern codes contain application rules based essentially on monotonic tests that allow the design of welded connections between a profile with H section and a plate or a beam flange without transverse...
Differential Equation of a Visco-Elastic Beam Subjected to Bending
Kelvin-Voight model Galerkin method finite differences method
2010/8/18
Generally, building materials exhibit a rheological behaviour as a direct consequence of their fundamental material properties such as elasticity, viscosity and plasticity. Based on the Kelvin--Voight...
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...
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...
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...
An Overview of Research at HKU on HSRC Columns and Beam-Column Joints for Low-Medium Seismic-Risked Regions
Low-Medium Regions
2009/1/15
Up to now building structures in Hong Kong (HK) are not required to resist earthquake effects. The design is based primarily on strength without taking into account any ductility consideration. Theref...
Structural Behaviour of Trapezoidal Web Profiled Steel Beam Section using Partial Strength Connection
Structural Behaviour Trapezoidal Web Strength Connection
2009/1/14
Connections are usually designed as pinned which associated with simple construction or rigid which is associated with continuous construction. However, the actual behaviour falls between these two ex...
