A rule used by some designers that has proved satisfactory is to design the brace for 2% of the axial load of columns, or 2% of the total compressive stress […]
EK611
For an ideally straight, exactly concentrically loaded beam or column, only a small force may be needed from an intermediate brace to reduce the unbraced length of a column or […]
EK593
When the shear capacity of the beam is exceeded, the shear failure occurs by excessive shear yielding of the gross area of the webs.
EK591
In a mono-symmetric beam there is an imbalance and the resistant torque causes a change in the effective torsional stiffeners, because theshear centre and centroid are not in one horizontal […]
EK585
When the width to thickness ratio is sufficiently small, the beam can be fully plastified and reach the plastic moment, such section are classified as compact sections.
EK567
The modulus of rupture is the maximum tensile stress reached in the bottom fibre of the test beam and calculations are based on elastic theory. Stress is assumed to be […]
EK433
The torsional resistance of a beam twisting about its longitudinal axis is usually divided into: uniform (St. Venant) torsion and non-uniform (warping) torsion.
EK431
The response of the beam remains linear and elastic almost to the stage when the stress in the extreme fibre has reached the value of the yield stress. From there […]

EK396
The deflection and rotation of the beam due to its loading will cause a concentration of bearing at the front edge and, depending upon the load from above the bearing, […]
EK366
Rigidly-jointed frames, or sway frames, are those with full moment resisting connections between beam and columns.
EK337
The form of the distribution of shear stresses is dependent on the shape of the cross-section of the beam, and on the direction of application of the shearing force.
EK297
After diagonal cracks have developed, shear reinforcement augments the shear resistance of a beam, ad a redistribution of internal forces occurs at the cracked section.
EK293
If the inclined crack starts at the top of an existing flexural crack and propagates into the beam, the crack is referred to as flexural shear crack.
EK292
An inclined crack occurring in a beam that was previously uncracked is generally referred to as a web shear crack.
EK285
The variation in the lever arm along the beam length is small and is never less than the value obtained at the section of maximum bending moment. Thus, it may […]
EK273
Usually secondary flexural cracks are widely spaced, and one crack does not influence the formation of others. They are expected to occur under low loads, such as dead loads. When […]
EK213
When a beam is bent elastically by a system of transverse loads, plane sections no longer remain plane after bending, but are warped by shear strains.
EK153
One of the most common methods of designing frames with simple joints is often used for rectangular frames with vertical (column) and horizontal (beam) members under the action of vertical […]
EK149
If the beam was statically indeterminate, the plastic hinge does not reduce it to a mechanism, and it can support any additional load. This additional load causes a redistribution of […]
EK148
If the beam was originally statically determinate, plastic hinge reduces it to a mechanism, and prevents it from supporting any additional load.
EK147
As the load on a ductile steel beam is increased, the stresses in the beam also increase, until the yield stress is reached. With further increases in the load, yielding […]
EK118
A reinforced concrete beam will initially behave elastically throughout, as the applied uniform moment is increased. When the limiting tensile strain for the concrete is reached a crack will form, […]
EK108
The lateral deflection of a story-high rigid frame due to beam and column rotations may be considered analogous to the shear defections of a story-high segment of a shear wall.
EK98
The action of a reinforced concrete beam in shear is represented by analogous truss in which the longitudinal reinforcement forms the bottom chord, the stirrups are the vertical members and […]
EK93
Assumptions of the Bernoulli-Euler theory of bending: The beam is bent by pure terminal couples so that shear and axial forces are not present. The deformations are small, so that […]
EK86
Figure represents the distribution of principal stresses across the span of a homogeneous concrete beam. The direction of the principal compressive stresses takes the form of an arch while the […]
EK45
Let the beam be subjected to bending in the plane of symmetry. If the bending moment is small, the stress and the strain vary linearly across the section. When the […]
EK39
The shear center is defined as the point on the cross-section of a beam through which the resultant of the transverse loads must pass so that the stresses in the […]
