In structures subject to a very large number of cycles of fluctuating load, typically at least 100000 load applications, failure may occur by the continued growth of cracks in the […]
EK543
When the pull on the bar is small, high stresses develop near the loaded end of the bar; some slip of the bar occurs as adhesion between the bar and […]
EK537
The splitting resistance of concrete can be enhanced if confinement stresses are superimposed onto the tensile ring stresses around the reinforcing bar.
EK528
In the case of deformed bars, bond stresses are transferred mainly by mechanical interlock.
EK519
As long as the stresses remain below the preconsolidation load the soil is reasonably stiff, but beyond the preconsolidation load the bahavior will be much softer.
EK472
Creep rates increases with higher stresses and temperatures. With lower stresses and temperatures, creep rates decrease but failure usually occurs at lower overall strains.
EK446
Calculation of the stresses in a thin shell generally is carried out in two major steps, both usually involving the solution of differential equations. In the first, bending and torsion […]
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, […]
EK344
When the stresses on an element act only in one plane, the state of stress is called plane stress.
EK321
Too much water in the mix creates water reservoirs. Channels lead from the reservoirs to the surface, where a watery laitance forms. A weak surface results, leading to concrete crazing, […]
EK282
Splices should not be made at or near sections of maximum moments or stresses.
EK218
If warping is prevented by rigid supports at the ends of the member, the torsional stiffness is increased and longitudinal tensile and compressive stresses are induced.
EK214
The simple theory of bending is based on the assumption that plane sections remain plane after bending. In reality shear strains cause the section to warp. The effect in the […]
EK203
The entire procedure of the finite element method involves the following steps: The given body is subdivided into an equivalent system of finite elements. Suitable displacement function is chosen. Element […]
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 […]
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 […]
EK55
In plane stress problem the only nonzero stresses are those in the plane of the problem and normal to the lamina we have no stresses.
EK48
Outside the kern, a load produces stresses of different sign.
EK42
In a bolted joint based on the plastic theory the end bolts are assumed to be stressed to their yield point. As the total load on the connection be increased, […]
EK41
The loads resisted by the bolts of a group are never equal (in the elastic range) when there are more than two bolts in a line. If the plates be […]
EK40
The assumption has been made that the loads applied to a connection are equally divided between the bolts. For this distribution to be correct the plates must be perfectly rigid […]
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 […]
EK31
In the elementary theory of bending, stresses and deflections in beams are directly proportional to the applied loads. This condition requires that the change in shape of the beam due […]
