Permissible stress design. Permissible stress design (in USA construction more commonly called allowable stress design) is a design philosophy used by civil engineers. The designer ensures that the stresses developed in a structure due to service loads do not exceed the elastic limit.

In materials science, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. The field of strength of materials deals with forces and deformations that result from their acting on a material.

The study of strength of materials often refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts.

Strength of materials, also called mechanics of materials, is a subject which deals with the behavior of solid objects subject to stresses and strains.

Each section of the Code uses design criteria and design stresses appropriate for the components that it covers. The basis for establishing allowable stresses is related to the design philosophy, the type of construction permitted, the degree of analysis required, and the amount of nondestructive examination mandated. Sections I, IV, and VIII, Division 1, use a design approach sometimes called design-by-rule.

Before getting too deep into this section, it would be wise for your to read the AISC Steel Construction Manual (SCM) sections describing the Load and Resistance Factor Design and Allowable Strength Design philosophies as well as the section on Design Fundamentals. These are found on pages of 2-6 and 2-7 of the SCM. Until AISC introduced the Load and Resistance Factor Design (LRFD) specification in 1986, the design of steel structures was based solely on Allowable Stress Design (ASD) methodologies.

allowable cut. noun, Ecology. 1. the amount of a natural resource, as grain or oil, that may be harvested or taken from the earth within a specified period, as limited by law for conservation. Also called allowable, permissible yield, prescribed cut.

In engineering, shear strength is the strength of a material or component against the type of yield or structural failure where the material or component fails in shear. Ashear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force.

The allowable stress or allowable strength is the maximum stress (tensile, compressive or bending) that is allowed to be applied on a structural material. The allowable stresses are generally defined by building codes, and for steel, and aluminum is a fraction of their yield stress (strength): In the above equation, is the allowable stress, is the yield stress, and is the factor of safety or safety factor. This factor is generally defined by the building codes based on particular condition under consideration.

Yeild stress divided by factor of safety is called allowable stress,now what is facor of safety(fos)…well its a safety factor as name implies ,if fos is 3 ,then it means u r multiplying 3 to allowable stress ie you have got 3 times safety of that metal ,yield stress is that point where failure starts to occur, failure doesnt means breaking,it means ...

define allowable stress
The maximum stress like tensile, compressive or bending that is allowed to be applied on a structural material is call allowable stress.   The allowable stress is defined as the maximum stress that is allowed to be applied on a structural material. Allowable stress is the maximum stress that is allowed to be applied on a structural material.
