pycba.load#
PyCBA - Load module
The load matrix represents the loads as a List of Lists. Each list entry represents a single load and must be in the following format:
Span No. | Load Type | Load Value | Distance a | Load Cover c
Load Types are:
1 - Uniformly Distributed Loads, which only have a load value; distances a and c are set to “0”.
2 - Point Loads, located at a from the left end of the span; distances c is set to “0”.
3 - Partial UDLs, starting at a for a distance of c (i.e. the cover) where $L >= a+c$.
4 - Moment Load, located at a; distances c is set to “0”.
It has dimension M x 5, where M is the number of loads applied to the beam.
The type alias LoadMatrix is defined as
- LoadMatrix#
The central part of internal API.
This represents a generic version of type ‘origin’ with type arguments ‘params’. There are two kind of these aliases: user defined and special. The special ones are wrappers around builtin collections and ABCs in collections.abc. These must have ‘name’ always set. If ‘inst’ is False, then the alias can’t be instantiated, this is used by e.g. typing.List and typing.Dict.
