tilt-up precast concrete
tilt-up precast concrete
(OP)
I have few questions regarding Tilt-ups sine I only do them every few years:
1. I am used to leaving a slab trip edge at the perimeter wit ha slope of 2:1 to keep soil stabilize soil. Is this technique still in use?
2. I will ask specialty engineer to design the panels, their connections, lifting for wind load, gravity load and shear (the panels will act as shear walls). Is this still common practice?
3. I have used a master section in the past. Are there any good sites for an up to date section 03470?
Your input would be appreciated.

I usually design the panels for everything except for the lifting inserts. They are usually done by the insert provider Burke etc.

This would be a good question for http://www.tilt-up.org/forum/
1. As haynewp mentioned the pour strip is common. Dowel rods into the footing & shim placement with angles bolted to the footing against the bottom of the wall. Embeded angles into the edge of the slab and field welded to embed plates in the wall are common although may other methods are used, inverted angles and patented inserts.
2. Many more firms are providing the total design package because tilt-up is becoming more prevolent and with programs such as Enercalc avaliable. One the other hand, some firms leave the connection up to the contractor to supply the design for approval. I recommend seeking out local tilt-up contractors for their input and then provide a design based on these standards.

It is a good concept. However, Texas would add lots of cost. This project has lots of panels that will be around 45 foot high.
I appreciate the input from the gang.
