Stress Analysis of a Stilt House
A view of the actual house analyzed for this project.
Simplified structure with two fixed-free columns under the load of the house, P. By symmetry, load is evenly distributed between the beams.

FEA Practicum #2
Elevated houses are common structures built to avoid flooding in areas threatened by hurricanes or storm surges. This project analyzed an interesting beam structure supporting an elevated house and its porch designed and built by the Gulf Coast Community Design studio (GCCDS), which is sponsored by Mississippi State University. The beams were analyzed for maximum deflection as well as the maximum forces and stresses on its members as a final project for my Stress Analysis course at NU.
The truss system was created in ANSYS 15 and assumed loading at nodes 1-3. Three cases were created to study the structure:
​
-
Case 1 modeled the beams using Red Cedar Wood as their material
-
Case 2 modeled the beams using Red Cedar Wood as their material, with the exception of beams 4-6 and 5-7. These used concrete as their material.
-
Case 3 modeled the beams as Case 2, except that the load applied on node 1 was 300kg instead of 100kg.
