# How safe is my patio and how much weight could it support?

I live in a three story apartment. I have a patio which also has a storage off of it. The actual patio is 8 X 10 and made from decking boards. However the exterior corner is supported by a 4 X 4 for three stories. How much weight could that possibly hold? I am a large man and could 3 or 4 guests cause an unsafe situation?

About how much weight could my patio support with one corner being just 4 X 4? Just looking for safe options. I also have plants on my patio which could take up about 200 LBS.

• I do not like the numbers that come out of this column calculator when I use a 20 foot (x and y unbraced) 4x4". courses.cit.cornell.edu/arch264/calculators/example7.1/… Knowing more about the geometry and bracing as you do, you may come up with more reassuring numbers. Apr 6, 2015 at 19:44
• Usual situation would be braced every 8-10 feet (by the porch/patio below) in multistory applications. But a picture would help, some. Apr 6, 2015 at 22:11
