A moment frame is a structural system designed to resist lateral forces through rigid connections between beams and columns, allowing for the transfer of bending moments. This system is crucial in providing stability and flexibility to buildings, particularly in seismic regions, by allowing controlled deformation during an earthquake.

Moment Frame

A structural system is an organized framework that supports and transmits loads in a building or structure, ensuring stability and safety. It involves the integration of various components like beams, columns, and foundations to efficiently manage forces and stresses throughout the structure.

Structural System

Lateral forces are horizontal forces acting on structures, often caused by wind, seismic activity, or uneven ground pressure, and they play a critical role in the stability and design of buildings and infrastructure. Engineers must account for these forces to ensure structural integrity and safety, using techniques like bracing, shear walls, and base isolators to mitigate their effects.

Controlled deformation

An earthquake is the shaking of the Earth's surface resulting from a sudden release of energy in the Earth's lithosphere, often caused by tectonic movements or volcanic activity. This natural phenomenon can cause significant destruction depending on its magnitude and location, and is measured using the Richter or Moment Magnitude scales.
