Is it possible to figure the area of rebar required for a concrete pier or column based on the given percentage (1%) and the size of the concrete member? I know you need the factored load typically, but I just wondered if we could figure it without?
I am working on a budgetary number for a parking ramp. The large footing pads do not have an actual rebar design yet, but there is a note stating that the reinforcing requirements shall be 1% of the concrete volume.
The sizes are as follows:
10-0 x 10-0 x 28" (8.641975 CY or 233.3333 CF)
12-0...
Thanks for everybody's input.
No, I am not an actual Engineer or Contractor. I am working on an Architecture degree but really enjoy the structural side of things. Unfortunately, the college I go to does not offer more than just a basic structural theory class. I have taken it upon myself to...
I have a wood beam running parallel to a concrete wall. The beam is an edge beam for a new deck design and need to know how to properly design the expansion bolts connecting the beam to the wall. Can someone please offer some help?
Thanks!

I know that Hilti makes a wide selection of different anchor systems. It seems that the traditional anchor bolts have been the design choice for all types of construction.
When it comes to residential, would you consider using Hilti anchors for anchoring the column baseplates to the supporting...
A good equivalent to #4 @ 12" EW is 6x6 - w2.1/w2.1 Welded Wire Fabric (WWF). It typically is purchased in 8x15 sheets or sometimes longer rolls and depends on your local area.
The design ended up with mat foundations. All of the larger interior and exterior loads are now supported by mats that are roughly 190-0 x 60-0 x 6-0 deep.
Thanks for everyone's input.
Yes. The proposed underground parking garage supporting the future buildings will have typical interior column loads (service loads) of 4,000 to 5,000 kips and interior column loads of 1,500 to 3,700 kips. For the portion of the parking garage supporting the new street, typical exterior column...
I was able to obtain the required bar sizes. Thank you for everybody's input. For those who are interested, here are comments from the GeoTech report for the project.
Spread Footings and Mat Foundations are recommended. The maximum net allowable soil pressure of 15 ksf bearing on medium...
I am looking for an easy way to figure out rebar sizes for footing pads supporting large columns in an underground parking ramp. The dimensions of the pads have been determined - some are combined and others are individual. This is for a budget price. I need to make sure I have the proper bar...
