# StructuralAnalysis
Library to perfrom framed structures analysis
## Installation
Use the package manager [pip](https://pip.pypa.io/en/stable/) to install StructuralAnalysis.
```bash
pip install StructuralAnalysis
```
## Requirements
The following packages must be installed first:
```bash
pip install numpy==1.19.5
pip install PyOpenGL==3.1.5
pip install PyQt5==5.15.2
pip install pyqtgraph==0.11.1
```
## Usage
```python
# Two_Story_Frame.py
from StructuralAnalysis import Node, Structure, Section, Material, Solver, Visualization
from StructuralAnalysis.FrameElements import *
# General considerations:
# - y-axis is upward
# - use consistent units
# - each node has 6 degrees of freedom dx: dof_1, dy: dof_2, dz: dof_3, rx: dof_4, ry: dof_5, rz: dof_6
# create node objects <Node(x, y, z)>
n1 = Node(0, 0, 0)
n2 = Node(6000, 0, 0)
n3 = Node(0, 0, 6000)
n4 = Node(6000, 0, 6000)
n5 = Node(0, 6000, 0)
n6 = Node(6000, 6000, 0)
n7 = Node(0, 6000, 6000)
n8 = Node(6000, 6000, 6000)
n9 = Node(0, 12000, 0)
n10 = Node(6000, 12000, 0)
n11 = Node(0, 12000, 6000)
n12 = Node(6000, 12000, 6000)
# create section object

# create material object

e911 = FrameElement(n11, n9, user_defined_section, steel)
e1012 = FrameElement(n10, n12, user_defined_section, steel)
# create truss element object
e16 = TrussElement(n1, n6, rectangular_section, steel)
# assign boundary conditions; node_1 is hinged, node_2, 3, 4 are fixed

# assign loads to node_10 in the x-direction, and to node_6 in the z-direction
n10.dof_1.force = 2000000
n6.dof_3.force = 4000000
# assign initial displacement to node_4 in the negative y-direction
n4.dof_2.displaced = -1000
# create structure object
structure = Structure([e15, e26, e37, e48, e56, e68, e87, e57, e59, e610, e711, e812, e910, e1112, e911, e1012, e16])
# run first_order_elastic analysis
Solver.analyze_first_order_elastic(structure)
# show undeformed structure
Visualization.show_structure(structure)
# show deformations <show_deformed_shape(structure, number_of_stations, scale)>
Visualization.show_deformed_shape(structure, 10, 1)
# show window
Visualization.execute_qt()
```
## Output
Upon running the above code, two text files ("Input.exe" and "Results.exe") are generated in the working directory.
The "Results.txt" contains the displacements and reactions solved for. The following window pops up showing the undeformed structure
(white) and the deformed shape (red).
The axis colors are as follows:
- Blue : X-axis
- Yellow: Y-axis
- Green: Z-axis
## Gallary
Python files for below pictures can be found in the "Examples" folder.
* Examples/ Hinged_Fixed_2D_Frame.py
* Examples/ Pyramid_Frame.py
* Examples/ Two_Story_Frame.py
* Examples/ Frame_Truss.py
## Under Development
The following enhancements will be included soon:
* Releases at element end nodes.
* Non-nodal loading.
* Straining actions diagrams
* Initial thermal straining.
* Second-order elastic analysis.
* First-order inelastic analysis.
* Second-order inelastic analysis.
* Eigenvalue analysis of buckling.
* Dynamic analysis
## Considerations
Kindly note that the library is still under development, errors may arise as
the library has not been tested and exceptions have not been handled. The visualization depends on graphics library
"PyQtGraph" which is still in its early stages of development, as a result, some of the features of displaying texts
(i.e., node labels, axis labels, ..) have not been included yet.
