A colleague working with a composting toilet company, with whom we have worked, asked me an engineering question I could not answer. I pose this question to you and ask that, if you can help answer it, respond to my email address: resource@world.std.com or fax me at 617 522-0690. Thank you very much. The question: We have a composting toilet base (specs below) that currently has a superstructure (bathroom) made of 2" sandwich panels. We are considering using other materials, including wood, for the superstructure, but we do not know the weight bearing load of the base. What is the maximum weight bearing load of the base? Specifications on the base: The base is made of rotationally molded high density linear polyethylene resin that conforms with the following specifications: Density (ASTM D792) 0.946 TG/CM3 Tensile Strength at Yield (ASTM D638): 3650 psi Impact brittleness Temp (ASTM D746-79) <-178 F Dart Impact (-40C, 125 mil thickness): 130 FT-lb Envt Stress Crack Resistance (D 1693-70) >1,000 hrs Base Size: Length: 115 inches (292 cm) Width: 65.5 inches (166.4 cm) Height: 48 inches (121.9 cm) (essentially a rectangular box with no top) Estimated Building size: Length: 88 inches (223.5 cm) Width: 67 inches (170.2 cm) Height: 88 inches (223.5 cm) Overall weight of existing building and compost base: approx. 1800 lbs Thanks.
