An Improved Static Seismic Design Method for Podium Structures with Vertical Irregularity of Mass and Stiffness
(University of Waterloo, 2021-01-12)Owing to potentially reduced costs and faster project timelines, North American designers are increasingly opting for novel structural systems that are not well-addressed by the current model codes. Specifically, mid-rise ... -
Performance of Load-Bearing Cold-Formed Steel Wall Systems with Web-Perforated Studs Subjected to Standard Fire
(University of Waterloo, 2017-01-23)Load-bearing cold-formed steel (CFS) wall systems are commonly constructed with CFS C-shape studs with one or two layers of fire-rated sheathing attached to both sides. In practice, perforations are placed in stud webs to ... -
Simplified Seismic Design for Mid-Rise Buildings with Vertical Combination of Framing Systems
(University of Waterloo, 2016-01-11)The mid-rise building with vertical combination of framing systems consists of a structural system in which the seismic-force-resisting-system (SFRS) of the upper structure is commonly a lightweight structural system such ... -
The Storey-Based Stability of Steel Frames Subjected to Variable Gravity and Fire Loading
(University of Waterloo, 2020-02-20)The concept of storey-based stability has been developed over the past several decades, and includes powerful methods to holistically assess the structural integrity of unbraced and semi-braced steel frames. Recently, it ... -
Vibration Serviceability of Cold-Formed Steel Floor Systems
(University of Waterloo, 2017-01-18)Excessive vibration in response to human activities has been a significant problem associated with lightweight steel floor systems, especially cold-formed steel (CFS) floors. Methods for accurately predicting these vibrations ...
