Current design codes do not have comprehensive provision for the design of built-up sections reflecting the improvement in design strength. The modified slenderness ratio for built-up sections in the American Iron and Steel Institute (AISI) North American Specification for the Design of Cold-Formed ...
Built-up sections are commonly used in cold-formed steel (CFS) structures. The built-up sections are either welded or mechanically fastened based on the need and necessity. However, the current design standards lack specific design methods for CFS built-up members as the development is in progre...
APPLICATIONS OF BUILT-UP SECTIONS IN LIGHTWEIGHT STEEL TRUSSES Lightweight steel structures have been widely used in the construction industry. It is flexible and thus can be designed to cater for different usages. To enhance the application of cold-formed steel structures, innovative configurations....
Material and local buckling response of ferritic stainless steel sections 2015, Thin-Walled Structures Citation Excerpt : The reported weighted average material properties were used in the analysis of the existing experimental results. The obtained numerical results from the stub column models and existing...
One of the main challenges in welding structural sections is selecting the optimal welding sequences to minimize residual stresses and distortions. In welded structural sections, such as built-up steel box sections, residual stresses and distortions can lead to failures due to the non-uniform expansi...
Manikandan P., Sukumar S.: Behaviour of stiffened cold-formed steel built-up sections with complex edge stiffeners under bending. J. Civ. Eng. (KSCE) 19 (17), 2108–2115 (2015)Manikandan, P.; Sukumar, S.: Behaviour of stiffened cold-formed steel built-up sections with complex edge ...
Built-up section beams fabricated from several single sections are finding increasing use in the cold-formed steel (CFS) industry due to various advantages such as higher bending capacities, innovative new shapes, and elimination of eccentricity. However, a built-up beam is connected at discrete po...
In another embodiment, the upper and lower members are tubular and the connection means comprises a swaged portion integrally formed on the upper tubular member of one of the two adjacent beam sections and a swaged portion integrally formed on the lower tubular member of one of the two adjacent...
Built-up steel columns with battens at regular interval along their height are suffered from compound buckling and large shear deformations under axial loads. During seismic overloads, the local instability of components prevent column sections to develop their full plastic moment carrying capacities an...
Hello all, I have a cold-formed steel portal frame that I want to analyze under monotonic pushover and non-linear time history analysis. The sections in...
