A seismic design strategy, which is intended to be implemented within the framework of the
US seismic design provisions for steel structures, is presented for single-story steel …

Column stability during seismic events is a critical consideration for all steel-framed
structures, but is of particular importance for a unique class of steel frames called multitiered …

This paper presents a study on the seismic response of multi-tiered, braced steel frames.
The seismic demand and stability of the columns in a 4-tiered special X-braced frame …

Concentrically braced frames (CBFs) are widely used to resist lateral loads in buildings
because they are relatively simple and economical to design and construct. In tall, single …

Multi-tiered concentrically braced frames (MT-CBFs) are widely used in North America as
the lateral load-resisting system of tall single-storey buildings such as airplane hangars …

Multi-tiered braced frames are commonly used as the lateral load-resisting system of tall
singlestorey buildings or tall storeys of multi-storey buildings. This framing system divides …

Multitier concentrically braced frames (MTCBFs) are often employed as the lateral force-
resisting system in structures where a tall, single story is required. To create an MTCBF, a …

Multi-tiered braced frames (MT-BFs) are created when a tall single-story bay is divided into
multiple bracing panels over the height, with no diaphragms or out-of-plane column supports …

Multi-panel, tiered concentrically braced frames are commonly used in the lateral resisting
systems of industrial facilities for loads resulting from wind and earthquake. To date, minimal …

To advance the structural engineering profession; to provide the public with structures of
dependable performance through the application of state-of-the-art structural engineering …
