As STRUCTURAL STEEL is a very ductile material with high strength carrying capacity it is very useful to make earthquake
resistant buildings. It is a homogeneous material also. The member section and the structural system can be made very
efficient for economical design. As the steel is recyclable and reused it is a green material. The embodied energy for the efficiently
designed steel structure is less than the RC structure. For sustainable green building steel is the best material nowadays.
Moreover, pre-engineered and pre-fabricated faster construction methodologies help the development work to complete
within the stipulated time. Usage of wide flange rolled sections made the steel construction world easier. In this work large span
steel PEB warehouse has been made with knee connections at heavy moment locations. One 150m overall span PEB warehouse
frame @ 6m spacing has been analyzed in STAAD software with two intermediate supports @50m c/c distances and high wind
pressure corresponding to 47m/sec wind speed. After this analysis WPB 900x300x251.6 kg/m wide flange rolled section is used
as the basic member with knee connections for larger moments at continuous supports. Again one G+4 multistoried building
frame has been analyzed using EBF stability bracing systems for earthquakes with large column free areas. The bottom two
stories of column are made of UC 305x305x118 + 2 WEB PL. 100x10 THK. Top portion of column is made of UC 305x305x97.
Composite beams are made of UB 305x165x46 + 3000x200 THK slab connected with shear connection at end. Link beams
are made of ISMB 300 (Grade Fe 540B) connected with moment connections at end. Bracing members are made of star angle
2-L 130x130x12. The frames are subjected to earthquake force of Zone IV of IS: 1893 ??? 2016. Response spectrum analysis is
done for the frames in STAAD software. Base shear attraction is much less. The results are indicating towards steel building
technologies with more green effects by economy in use of materials and manufacturing process.
