Steel bar reinforcement, also referred to as rebar, comes in various diameters suitable for different structural concrete applications. This post outlines some of the most frequently used bar size diameters according to ASTM specifications.
#3 bar = 0.375 in diameter
#4 bar = 0.500 in diameter
#5 bar = 0.625 in diameter
#6 bar = 0.750 in diameter
#7 bar = 0.875 in diameter
#8 bar = 1.000 in diameter
#9 bar = 1.128 in diameter
#10 bar = 1.270 in diameter
Metric equivalents are also commonly used:
8mm rebar
10mm rebar
12mm rebar
16mm rebar
20mm rebar
25mm rebar
32mm rebar
Knowing standard rebar diameter designations can help select the appropriately sized bars for construction plans and bending schedules. The diameters listed above cover a wide range of reinforcing needs for slabs, beams, columns and other reinforced concrete elements.

22+ Photos of Damage Earthquake Column Concrete
Earthquakes and Concrete Columns: 22+ Striking Photos of the Aftermath
Concrete columns are a critical structural component in buildings, bridges, and other infrastructure, designed to support immense loads and keep structures standing strong. However, when a powerful earthquake strikes, these concrete columns can be devastated, revealing just how vulnerable they can be to the intense shaking and lateral forces.
In this photo essay, we've compiled 22 striking images that illustrate the catastrophic damage earthquakes can inflict on concrete columns. From cracked and spalled concrete to complete collapse, these photos demonstrate the need for robust seismic engineering and construction practices to protect our built environment.
1. Shattered Supports: The base of this concrete column has been completely destroyed, leaving the upper section unsupported and dangerously unstable.
2. Toppled Titans: Multiple massive concrete columns lie in ruins, underscoring the immense power of an earthquake to bring down even the most substantial structures.
3. Buckled Failure: Severe bending and buckling has rendered this reinforced concrete column useless, a casualty of the earthquake's lateral forces.
4. Crumbling Corners: Chunks of concrete have broken away from the corners of this column, compromising its structural integrity.
5. Twisted Rebar: The steel reinforcement bars inside the concrete have become badly distorted, indicating a complete failure of the column.
These images underscore the vital importance of designing and building concrete columns to withstand the extreme stresses of earthquakes. With robust engineering and construction practices, we can protect our infrastructure and save lives when the ground begins to shake. This photo essay aims to inspire further innovation in earthquake-resilient construction techniques.

What are Standard Stair Sizes? Code Requirements for Tread Depth, Riser Height and More
Here is a summary of standard stair sizes and dimensions:
- Tread Depth: Most codes require a minimum of 11 inches of tread depth. Common residential tread depths range from 11 to 12 inches.
- Rise Height: The maximum rise allowed by code is 7.75 inches. Common heights are 7 to 7.5 inches.
- Gooseneck: The distance between the stair nosings at a 180 degree turn is typically 36-42 inches.
- Width: Minimum width for a residential stair is 36 inches between handrails. Wider stairs are more comfortable for traffic flow.
- Headroom: Minimum clear height is 6 feet 8 inches measured from the stair nosings to the lowest projection above, like a ceiling.
- Overrun: The stair should extend past the floor above by at least 11 inches but no more than 12 inches for safety.
- Winders: The smallest tread on a winder stair should be at least 6 inches wide. The largest no more than 12 inches.
- Landing size: Minimum size for a landing is 36x36 inches. Standard is larger at 48x48 or 72x72 inches.
- Handrail height: Code requires handrails to be placed 34-38 inches above tread nosings.
Let me know if you need any other stair building specifications or have additional questions! Proper dimensions are important for code compliance and usability.
