Is it ok to attach a pressure-treated joist directly to a concrete slab as a foundation for a deck and should it be epoxied or bolted down?
You can set the joist directly into a 3 or 4 foot hole filled with concrete, however the life expectancy of the joist is about half when it does not come in contact with the ground at all. On my house I set them on metal brackets then epoxied the bracket bolt into the concrete. With pressure treated lumber this post will be "good as new" for 25 years. Depending on the area I have seen concrete ones disintegrate in 3-8 years.

What materials are used to build lightweight patio gazebos?
Aluminum is probably the best lightweight material to make a frame for a gazebo. You can even get Durawood brand which is aluminum coated to look like wood. EZ-up type canopies are really lightweight, with umbrella type canopies. A strong, pressure treated lumber should be used to construct the posts and frame of your gazebo. Cedar is the most popular choice. For the foundation, it is best to set the post frames into a slab of concrete, though a bed of rocks or gravel can serve for this purpose.
