Steel
Pros:
Steel can span greater distances with fewer support columns and can accommodate large expanses of glass. If your business requires showroom windows, steel framing would be the better building method for you.
Steel is more flexible and has good wind resistance
"Steel has the highest strength to weight ratio among building materials, including concrete. Steel is eight times (8X) stronger than concrete in tension and shear; steel is resilient unlike concrete; and steel has better resistance to tensile, compressive, and flexural stress." - escglobalgroup.com
"Steel Structure is economical. Huge portion of the market supply comes from recycling, making steel much cheaper than other materials. Being lightweight, it delivers huge reduction in labor cost due to easier handling and transportation and faster installation." - escglobalgroup.com
Constructed off site - fewer workers are needed to construct on site
Made from recycled materials
Better for earthquake resistance
Faster construction
Steel is low maintenance
There are six basic mechanisms of failure for steel structures:
Ductile yielding
Brittle fracture
Buckling
Fatigue
Stress corrosion cracking
Creep.
Concrete
Pros:
Few "cracks" or joins that could cause heat to escape
Has a thicker barrier to prevent damage and penetration
Highly wind resistant
Resistant to corrosion
Durability
Energy efficient
More soundproof than steel
Versatility
Energy efficient
Low maintenance
Can be recycled
Can be sourced locally
Great fo underwater or coastal use
No light reflection
What Factors Causes Failure of Concrete Structures?
The main factors that affect the failure of concrete structures are:
Incorrect selection of materials
Errors in design calculation and detailing
Improper construction techniques and insufficient quality control and supervision
Chemical attacks on concrete structures
External mechanical factors
