WebOn average steel building cost per square foot is $19. That includes the materials and the labor to construct. Steel buildings using I-beam construction are the cheapest option at $8 per square foot. While modular steel buildings are the most expensive option at $40 per sqft. Steel building kits start as low as $8,000 for 2 car garage. WebNov 5, 2024 · Shear wall-frame systems have been used successfully in buildings ranging from 10 storeys to 50 storeys. The difference in behavior under lateral load, in combination with the in-plane rigidity of the floor slabs, causes nonuniform interacting forces to develop when walls and frames are present. This makes the analysis more difficult. bjc total
