HEA Profile Carrying Capacity and Strength Values

HEA Profile Carrying Capacity and Strength Values

Although HEA profile is known as a construction element in terms of product group, it is a profile group that is also used in machinery and equipment construction areas. These profiles, defined by the abbreviation consisting of the initials of the high energy astrophysics word group, are used as carrier elements with high strength value. These profiles, which are generally used in architectural and construction areas, resemble the letter H when viewed from a cross-sectional point of view. Although the wall thicknesses vary industrially, they are generally between 80 and 400 mm.

Hea profile, which is preferred especially in steel structures due to its bearing, strength and aesthetic properties, is an extremely preferable material class in terms of features such as impact, dynamic fatigue, and creep in terms of bearing capacity. They are frequently used in steel construction constructions. They are classified and priced according to their size. HEA profile bearing capacity and strength values are determined by the Regulation on the Design, Calculation and Construction Principles of Steel Structures published in the Official Gazette No. 29614.

HEA profiles are defined according to EN 10088-3 as stainless steel bars or other stainless steel products. HEA profiles that are not made of stainless steel, on the other hand, are produced as iron or steel by recycling from scrap according to TS EN 10034 size standard and TS EN 10025 - 1/2 quality standard.

Standing out with its advantages such as high flexibility and extremely low cost, HEA profiles find a wide place in both trade and industry and production.

HEA profile strength values

HEA profile bearing capacity and strength values; It depends on parameters such as bending, pressure, strong axis, weak axis, cross section, surface area and design dimensions. HEA structural profiles can also be produced in S275JR quality or S235JR, S355JR, S355J2 grades. Although the weight of HEA profiles is less than HEB profiles, there is no difference in terms of usage and strength. HEA profile bearing capacity and strength values can be calculated with industrial software such as ANSYS and SAP, as well as manually. Since the working conditions of HEA profiles are within certain limits, strength calculation is also easy and common.

HEA 100 profile Strength Values

For example, HE 100 A strong axis and weak axis values are as follows.

Cutting Area

The HEA profile geometry is clearly defined in EN 53-62, DIN 1025/3. Total height h, flange width b, wall thickness Tw, flange thickness Tt and root diameter r;

Av,z = max( A – 2ITf + (tw + 2r)tf , ηtwhw )

It is calculated with the equation. (n value should be taken as 1.2 for steels.

elastic modulus

Whand,y = Iy / (h / 2)

Whand,z = Iz / (b / 2)

is calculated with.

HEA profile bearing capacity and strength values are calculated with the following formula, yielding stress (yield stress) of the material used, Fy.

ε = (235 MPa / fy)0.5

(235 Mpa should be used as the default value for steel.)
