This documentation explains the usage of the enginesheets. If you want to know how the backend will perform your calculations, read the Caleng Docs.

You have 4 types of forces sets: Full forces set (FFS), shear forces set (SFS), moment forces set (MFS) and axial forces set (AFS). The only difference between them is that some forces will not appear in some sets.
|Identifier||Force Description||Appearing in||Units|
|P||Axial Force||FFS, MFS, AFS||`kN`|
|M2||Bending moment 2-2||FFS, MFS||`kN*m`|
|M3||Bending moment 3-3||FFS, MFS||`kN*m`|
|V2||Shear 2-2||FFS, SFS||`kN`|
|V3||Shear 3-3||FFS, SFS||`kN`|
Normally, you will have both ULS and SLS forces sets in each enginesheet.
In a bolt array form, the user must choose the following parameters:
|Standard||Bolt size standard||Metric: ISO / Euro bolts (mm)
American: US bolts (inches)
Custom: User custom bolts
|Bolt size||Name of the bolt size. Builtin types are named as per its size||List of bolts from selected standard||None|
|Bolt grade||Bolt grade. Material properties are picked from this parameter||List of builtin and custom grades||None|
|EC3 Joint Category||Joint Category according to Eurocode 3 Table 3.2||A, B, C, D and E.
Categories may be unavailable in order to respect a specific joint constraint.
|Bolt holes||Holes standard according to Eurocode 3. Currently only normal or oversized.||Normal holes
|Surface Class||Only available in pretensioned categories: B, C or E.||A, B, C or D||None|
|p1||Serie of distances between bolts (Tekla styled)*||None||`mm`|
|p2||Serie of distances between bolts (Tekla styled)*||None||`mm`|
* To type a serie of distances, type each one separated by spaces. For example:
45 50 50 50 45. If you have the same distance several times, you can joint them with a *, just like this:
45 3*50 45. Another example is provided in the figure. Leave the field blank if you have only one column/row.
Tekla distances notation
Profiles are defined through two parameters: Type and section. In most enginesheets aditional parameters are needed. Check the specific docs of your sheet for more information.
|Type||Type of profile section.
Every section (being builtin or custom) must be categorized
|Pipe: Circular Hollow Section
Tube: Rectangular Hollow Section
H Shape: Includes H, I, Wide flange, and alikes
L Shape: Symmetrical or asymmetrical L shapes
U Shape: U or C shapes without lips
|Section||Name of the bolt size. Builtin types are named as per its size||List of sections from selected type||Usually `mm`|
Sometimes you can define an arbitrary profile position. Three parameters are needed:
|g1||Eccentricity in 1-1 direction||`mm`|
|g2||Eccentricity in 2-2 direction||`mm`|
First rotate and then traslate as stated in caleng docs.
Plate Position and Profile Rotation
A different approach when placing plates. This time you enter the plate displacement (and not the profile displacement). This was created for a better intuitive form input. The profile rotation remains the same.
|g1||Plate eccentricity in 1-1 direction||`mm`|
|g2||Plate eccentricity in 2-2 direction||`mm`|
|rotation||Profile rotation. Counterclockwise||`º`|
Basic parameters for plates are material and thickness. Width and length are required in most plate forms. If the plate is bolted, bolt-to-edge distances must be provided.
|Material||Steel material name||Steel material list (custom and builtins)||None|
|width||Plate width. Ussually perpendicular to the main force||None||`mm`|
|length||Plate length. Usually parallel to the main force||None||`mm`|
|e1||Bolt-to-edge distance in 1-1. Left (or negative values) side.||None||`mm`|
|e1*||Bolt-to-edge distance in 1-1. Right (or positive values) side.||None||`mm`|
|e2||Bolt-to-edge distance in 2-2. Left (or negative values) side.||None||`mm`|
|e2*||Bolt-to-edge distance in 2-2. Right (or positive values) side.||None||`mm`|
|e1=e1*||If selected, e1* will be autosolved as: `e1^**=e1`||Checkbox||None|
|e2=e2*||If selected, e2* will be autosolved as: `e2^**=e2`||Checkbox||None|
Pro Tip: What is the point with the bolt distances (e1, p1, e1*) direction?. We make them following the rules:
- e2, p2's, e2*: growing upside (+Z).
- e1, p1's, e1*: growing from left to right in our drawings.
- e1, p1's, e1*: If aligned with a profile axis, they grow from the profiles intersection. Like in S002.
- e1, p1's, e1*: If aligned with a profile section, they grow from left to right as viewed from the arriving to the landing. Like in S001.
