In addition, stud local buckling failure mode was observed, and it could be caused by the low anchor stiffness of using cleats instead of hold-downs. Join us in this one-hour course as we discuss cold-formed steel framing connection products that help ensure your building can withstand a variety of expected and unexpected issues throughout its lifespan. However, some minor but recoverable damages were also noticed. A safe and secure building begins with reliable, tested framing connections. The test results revealed that in addition to increasing the lateral stiffness of the structure, the hardboard sheathing also acts as an efficient bracing system. The sheathing was screw-fastened to the cold-formed studs and tracked for the development of shear stiffness and strength in the wall system. Historically a top performer in earthquakes, explore the details on CFS’ seismic performance with details on energy absorption, strength and consistency, ease of inspection, and corrosion resistance. For this purpose, three full-scale specimens (i) frame without sheathing, (ii) frame sheathed with 4 mm thick hardboard, (iii) frame sheathed with 10 mm thick hardboard were tested using a uni-directional shake table. Understand the facts about cold-formed steel framing’s safety, reliability, and ductility when the ground starts to shake. The main aim was to determine the contribution of sheathing in resisting lateral forces. In this study, cold-formed steel shear wall (CFSSW) response has been investigated with varied thickness of hardboard sheathing used as a structural element. This study aims at that neglected aspect. However, despite many studies, the examination of existing experimental studies demonstrates that the lateral bracing and stiffness provided by the sheathing are generally ignored, and sheathing is provided as a non-structural component. Many researchers have thoroughly studied the basic behavior of different sheathing (including walls sheathed with plywood, oriented strand board, gypsum wallboard, gypsum sheathing board, steel sheet sheathing, and fiberboard) with different thicknesses. Metal Furring Sizesīoth hat channels (left) and zee furring (right) are used to apply gypsum wall board to a concrete or CMU block wall.In the design of cold-formed steel (CFS) buildings, sheathings are used to provide lateral resistance to seismic or wind load. Ready Products for Hand-Bendable Curved Framing for Wood Construction. Structural cold-formed steel framing certification is independently validated by Architectural Testing. The taller leg of the J Track goes on the shaft-side of the wall to help hold the shaft liner in place. Architectural 2D plans and 3D models can be imported into Vertex BD from virtually any architectural software, streamlining the framing process and saving. A catalog for Connectors for Cold-Formed Steel Construction products and solutions. After the shaft liner is installed, gypsum wall board is installed as usual from the floor-side of the wall. The 1" portion of the stud holds a 1" shaft liner, which can be installed from the floor-side of the wall fasteners are not required to hold the shaft liner in place. Neilsoft has good experience and understanding of handling CFS elements and supports Architects, Engineers, General & Framing Contractors and Fabricators. and to accommodate live load deflection of primary building structure as follows. Shaftwall is used when only one side of the wall is accessible, as in mechanical shafts where there is no floor on one side of the wall. Structural Performance: Provide cold-formed metal framing capable of. Combined with a layer of 5/8" gypsum wall board on both sides will give a 4 7/8" thick wall. The most common size stud is a 3 5/8" wide stud.
The most common shapes are diagrammed below, with dimensions. The advantages of LGMF are many, including: light weight, no warping, easy cutting, and fast installation.Ĭold formed metal framing comes in many shapes and sizes. It is also being used in some residential applications. Cold-formed steel (CFS) members are made from structural quality sheet steel that are formed into C-sections and other shapes by roll forming the steel through. Cold formed metal framing, also referred to as light gauge metal framing (LGMF), has overtaken wood stick framing in commercial and institutional construction.
