MORREL, P. The behaviour of rectangular hollow section steel beams under concentrated flange loading. PhD Thesis, CNAA, Brighton University, January SALTER, P. Assessment of design using cold-formed hollow. Nine steel beams of cross-section W×28, labeled in Series A, B, and C, were tested under a four-point loading scheme with strengthening plates introduced by welding at various load levels.
Specimens, P1 and P2, were tested to failure without strengthening plates to obtain the capacities of the plain beams under the current test by: 8.
The paper presents experimental and numerical research into the strengthening of steel columns under load using welded plates. So far, the experimental research in this field has been limited mostly to flexural buckling of columns and the preload had low effect on the column load resistance.

Hollow Section. It’s not surprising that the steel hollow section is today regarded as the most efficient and versatile component in construction and mechanical manufacturing. Most of the world’s most impressive structures rely on the use of steel hollow sections. This work is intended to analyse the behaviour of steel beams under uniform temperature rising.
It covers beams under several uniform load levels and three boundary conditions: simply supported (pin-roller), simply supported with axial restraint (pinned-pinned) and both ends fixed (fixed-fixed).
Timber construction behaviour under load is affected by many factors that in most cases influence timber constructions in a negative manner.
Part of these influencing factors are properties of material, the other are components of the environment where the timber construction is located.

Behavior of Reinforced Concrete Beams Loaded by Transversal Bending Forces When this is applied on the reinforced concrete beam under load, after conducted analysis of behavior, the following can be concluded: in the section of the beam, above the neutral plane, normal compression stresses occur, while they are not present in the.
BEAM-COLUMNS SUMMARY: • Structural members subjected to axial compression and bending are known as beam columns. • The interaction of normal force and bending may be treated elastically or plastically using equilibrium for the classification of cross-section.

This paper presents the behaviour of hollow and concrete-filled mild steel tubular columns under static and impact loading. A total of three test series have been carried out recently at the University of Western Sydney and the University of Wollongong to investigate the performance of steel hollow and concrete-filled steel tube (CFST) columns subjected to static as well as impact loading.
In this paper the application of reactive reciprocal method is used to solve the concentrated load rectangular section of the deep beam bending problem.
The deep beams new equation of bent rectangular section is not only the use of the power of reciprocal method is used to solve the deep bending beam one of the innovation points, also abounded beam : Ying Jie Chen.Many structures can be approximated as a straight beam or as a collection of straight beams.
For this reason, the analysis of stresses and deflections in a beam is an important and useful topic. This section covers shear force and bending moment in beams, shear and moment diagrams, stresses in beams, and a table of common beam deflection formulas.
