4. Frame Analysis - part a
Frame structures combine beams, columns, and slabs to resist lateral and gravity loads, with distinctions between rigid and braced frame structures. Rigid frames offer high stability and effective resistance against moments and lateral forces, while braced frames enhance resistance through diagonal members. Load transfer in frame structures is crucial for their performance, making them advantageous over traditional load-bearing buildings in terms of flexibility, construction speed, and economical designs.

What we have learnt
- Frame structures are composed of beams, columns, and slabs designed to handle lateral and gravity loads.
- Rigid frames provide higher stability and resistance compared to other structures, particularly against shear and moment.
- Braced frames distribute forces more effectively and are often more efficient against lateral loads like wind and earthquakes.
Key Concepts
- -- Rigid Frame Structure
- A type of frame structure where beams and columns are integrated monolithically, effectively resisting applied moments and providing stability.
- -- Braced Frame Structure
- A structure enhanced by diagonal bracing to improve resistance against lateral forces, making it particularly effective in earthquake and wind scenarios.
- -- Load Path
- The trajectory through which loads are transmitted from the structure to the foundation, typically moving from slabs to beams, then columns, and finally to the foundation.
- -- Gabled Structural Frame
- A frame structure typified by a gabled roof, featuring a lightweight construction that minimizes earthquake damage and reduces foundation costs.
- -- Portal Frame Structure
- A frame that resembles a door, commonly employed for industrial and commercial buildings due to its efficient load-carrying capacity.
