Steel Takeoff Spreadsheet

Steel Takeoff Spreadsheet The angled weld beads arranged on both sides of the core of the beam are assimilated to a triangle of configuration of the approximate section of the bead.
We distinguish between two types of sturdy insoles within the cord:
Dropped planes are the two orthogonal planes that close the triangle of the approximate section.
Throat plane: it is considered to be the resistant plane of welding and forms 45º with respect to the planes shot.

INTRODUCTION TO CORD TENSIONS
The stresses acting on the weld bead are transformed into a determined tension. Recall that a stress is the relationship of an effort between a resistant area, so in the function of the working plane of the cord with which we work, you can speak of the following tensions:
Tensions in planes shot down: denominated with alphanumeric letters.
“N” is the normal calculation voltage acting perpendicular to the plane of one of the faces of the weld bead.
2 is the tangential stress of normal calculation to the edge contained in the plane of one of the faces of the weld.
3 is the tangential calculation voltage parallel to the edge contained in the plane of one of the faces of the weld.

Tension in the throat plane: denominated with Greek letters.
4 is the normal stress perpendicular to the plane of the cord crosssection; It is parallel to the direction of the cord.
5 is the normal calculation voltage acting on the throat section.
6 is the tangential stress of calculation normal to the edge directed to the throat plane.
7 is the tangential computing stress parallel to the ground with the throat plane.

TENSION CONVERSION
It is customary to identify in the first instance the stresses in the drawn planes 8 and, according to the request on the union, to transform these stresses of plane collapsed and tensions on the plane of throat 1 For this it can make use of the following expressions:
