Impact of Fastener Spacing on the Behavior of Cold-Formed Steel Shear Walls Sheathed with Fiber Cement Board
(2020-10-20)As cold-formed steel (CFS) is progressively used in high seismic regions as part of the designated lateral force resisting system, it is necessary to explore higher capacity systems. Furthermore, these systems must be fully ... -
Impact of gravity detailing on the thermal performance of cold-formed steel wall assemblies
(2020-10-20)Considering building thermal performance in addition to structural performance is paramount to sustainable design. Structural systems bleed heat from interior to exterior through thermal bridges, structural elements that ... -
Incorporating cold-formed steel member and system design into the undergraduate curriculum
(2020-10-20)Cold-formed steel design, in an ideal scenario, deserves an entire advanced undergraduate or graduate level course. However, this is not practical in many institutions, where a program of study can only include a few courses ... -
Large Deflection Analysis of Beam-Columns with General Sections Using Gaussian Line-element Method
