EK644
Uplifting failure occurs when there are not enough loads to resist the hydraulic pressure.
EK604
When a system of loads is applied to an elastic body, it will deform and will show a resistance against deformation. Such a body is known as a structure.
EK573
Although steel tension members can sustain loads up to the ultimate load without failure, the elongation of the members at this load would be nearly 10-15% of the original length […]
EK557
Frame analysis for non-linear behavior can be made either by simulating a load control or deformation control test setup. In the latter approach, a set of deformations is increased to […]
EK544
The distribution and magnitude of bond stresses along a bar are difficult to establish quantitatively. One problem is the progressive shifting of the bond distribution along the bar as bond […]
EK539
Compressive stress fields induced by applied loads, reactions, and prestressing are considered to be active confinement.

SOFTWARE: 2D Truss Analysis DEVELOPER: EngiSSol LINK: https://www.engissol.com/demos.html PLATFORM: Windows MAIN APPLICABILITY: Software for static analysis of 2D trusses. MAIN FEATURES: Possibility to create 2D truss of any shape. Possibility […]
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 […]
EK211
A structure should be designed to be safe under all conditions of its useful life and to ensure that this is accomplished certain distinct performance requirements, called “limit states“, have […]
EK210
It is therefore accepted that 5% of the material in a structure is below the design strength, and that 5% of the applied loads are greater than the design loads. […]
EK207
When a simply supported steel “I” beam bends under downward loads the extreme fibres at the top of the beam are in compression. This puts the top flange of the […]
EK174
The central concepts of limit state design are as follows: All the separate conditions that make the structure unfit for use are taken into account. These are the separate limit […]
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 […]
EK138
In triangulated structures with joint loads, any flexural effects are secondary, and the members can be assumed to act as if pin-jointed.
EK46
Requirements for the principle of superposition to apply: The material must behave in a linear-elastic manner. The geometry of the structure must not undergo significant change when the loads are […]
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 […]
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 […]
EK01
The principle of superposition states that the deflection at a given point produced by several loads acting simultaneously on the structure can be found by superposing deflections at the same […]
