Structural Engineer 2d
Welcome to the definitive structural calculator for Android: solve plane frame analysis using the Stiffness Method that provide an exact and fast solution to the problems designers face. The information saved in the generated files, within the “Reports - StructuralAnalysis2d” folder, located in the internal storage of your device:

We offer a professional input for each cross section, node, element and load that´s presented. This allows you to customize the location of each structural member, which gives our users greater versatility, to model situations that occur in real life, every day. Once the app performs the analysis, it prints the results on screen (reactions and displacements in each node), so that the user can verify them.

In the free version the user can create up to nine nodes and has the option of watching a promotional video (to keep the app free) when the analysis run. If it does, the app print a report in .txt format with the following information: data of the cross-sections created, element data, structure data (such as the total stiffness matrix), data of the applied loads (for analyze), known loads (Qk), known deflections (Dk). Finally the results, which includes the vector (Du) that contains the unknown displacements in the structure. Then, the equation (Qu = k21 * Du) is applied, which is solved for (Qu), the vector of the reactions in the nodes. These reactions overlap with equivalent applied loads, to get final loads, for design purposes.

Then print the internal loads in elements. The result of the final load applied to the element, overlap with perfect embedment condition, defined by the load condition applied on element. This results are calculated for each element of the plane frame, so you do the structural design!!!

The whole procedure is based and tested with the problems of chapter 16 (Analysis of plane frames using the stiffness method) of the eighth edition of structural analysis book by R. C. Hibbeler.

How to use:
1. Select the units to work.
2. Create the necessary cross sections to model your structure, according to the material and the shape of the elements.
3. Create the nodes that make up your structure: assign XY coordinates and tell the app if it is support or not. If it is support, it is fixed (3 reactions: xyz) or pinned (2 reactions: xy).
To run the app you need to have at least three nodes and two elements created. If you want to analyze a single beam, you can create an intermediate node and divide the element in two.
4. Create the elements that make up the plane frame, assigning start (N) and end (F) node, as well as the corresponding cross section.
5. Model the load condition to which your structure is subjected, creating one load at a time. You must assign which element is being applied, the type of load (punctual, distributed, triangular or moments), enter the magnitude and distance "A" measured from node N, to the point of application of the load, as shown in the buttons.
6. Press the red button to run the analysis and see its results.

The graphical interface has a grid at every m or ft, highlighted at every 5 units, to visualize large frames.
