Both braced frames and moment frames are employed in the construction of structures that are exposed to lateral loads like earthquake and wind force. This is especially true when it comes to tall structures in which the forces from the lateral are the primary factor in design.
In braced frames the columns and beams generally are placed in an orthogonal pattern on both the elevation as well as on the plan. These structural components are linked with pin connections that do not transfer any moments.
In frames that resist moment the structural components are joined using rigid joints, which transfer force. Thus, the moment resisting frame relies on joints to transfer loads onto the foundation.
Bothbraced frames and moment resisting frame serve the same job of resisting the lateral load and providing stability, however different mechanisms are employed for each. This is the reason it is essential to be aware of the differences between these different structural frameworks.

Frame with brace Frame resists moment
A pin connector is utilized to create beam-column joints. A rigid connection, as illustrated in Fig. 1 is used to connect beams and columns.
The connection is not able to transfer the moment. Moments are transmitted through the connection.
It is dependent on the bracing system as illustrated in Figure. 2. load to the foundation. Bracing systems for vertical and horizontal bracing are employed. It is based on the solid connection to transfer loads lateral onto the foundation.
The study of braced frames structure is simple and straightforward. The investigation of the relationship is quite complicated.

It's not labor-intensive. It is extremely labor-intensive.
Cost-effective because of the pinned connection that is easy to understand and simple to make. It is expensive to build.
Stabilizes the structure. The stabilization method isn't as effective as braced frames.
Braced frame is mainly used for the construction of timber and steel structures. Reinforced concrete structures naturally employ frames that resist moment.
Columns and beams are studied in the context of vertical loads only in the assumption that the bracing system can support all the lateral loads. Columns and beams are examined under axial loads and moment.
In the minimum there are three vertical planes for bracing are required, to ensure the necessary resistance both within the plan, as well as to resist towards torsion along an axis vertical. All connections are solid.
It is less deformable and has more stiffness in comparison to frames with a moment resistance. Moment resisting frames offer more flexibility in deformation and are less stiff when compared with braced frames.
