A frame is considered to be non-sway (braced) if it is sufficiently braced by lateral bracing elements like structural walls. On the other hand, frames that provide lateral resistance only through columns are considered to be sway frames (unbraced). ACI ...

Analysis Methods for Buildings Frames
Elastic analysis deals with the study of strength and behavior of the members and structure at working loads. Frames can be analyzed by various methods. However, the method of analysis adopted depends upon the types of frame, its configuration (portal ...
Approximate Lateral Load Analysis by Portal Method
The portal method is an approximate analysis used for analyzing building frames subjected to lateral loading such as the one shown in Fig.1. This method is more appropriate for low rise buildings with uniform framing. Portal Method of Analysis Assumptions ...
Analysis of Moment Resisting Frame and Lateral Load Distribution
Lateral Load Distribution of Frame Building In a two dimensional moment resisting frame each joint can have at the most three degrees of freedom (displacement in horizontal and vertical directions and rotation). Total number of degree of freedom is 3Nj ...
