ACtrafficengr - We do utilize both cast-in-place & pre-cast structures for our extremely large ponds. However, for intermediate size ponds we have found that concrete is almost always cost prohibitive. Exposure to extreme cold is one of my concerns with using HDPE (we get exceptionally cold...

My apologies, I have attached a better sketch. To answer your questions, the support is at the end of the horizontal member. This was a general question in regards to the mechanics of it which is why I did not provide a material (I have seen this scenario with both wood and steel) but if it...
Alright I am hoping someone can help me with some basic mechanics of materials, maybe I am just overthinking this but I can not decide the proper way to tabulate the shear stress. The attached image shows two members which will be fastened with a plate (much like the heel joint of a truss or...
Wondering if anyone has dealt with a similar situation or has good ideas on how to resolve this....
