Perforated Steel Stud to Improve the Acoustic Insulation of Drywall Partitions
نویسندگان
چکیده
Steel studs are an inevitable part of drywall construction as they lightweight and offer the required structural stability. However, act sound bridges between plasterboards, reducing overall insulation wall. Overcoming this often calls for wider cavity walls complex stud decoupling fixtures that increase installation cost while floor area. As alternative approach, research reveals potential perforated to improve acoustic partitions. The performance is characterized using a validated finite element model acted prediction tool in number physical tests required. results established numerical featuring fluid-structure-interaction can predict weighted reduction index wall assembly at accuracy ±1 dB. was used analyze six designs found them outperform non-perforated partitions by bridging. Overall, best performing design improvements up 4 dB, being structurally compliant.

Cyclic Behavior of Cold-Formed Steel Stud-to-Sheathing Connections
This series of experiments aims to characterize the cyclic behavior of cold-formed steel (CFS) stud-to-sheathing connections. This connection provides the key energy dissipating behavior in wood sheathed CFS shear walls, and provides bracing to the studs under gravity and out-of-plane loads. A simple testing rig is developed consisting of two CFS lipped channels facing toe-to-toe connected on t...
متن کاملStudy of the effect of shape on acoustic performance of micro perforated absorbent at low frequencies
Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...

Steel-concrete-steel (SCS) sandwich panels are composed of two steel plates with low thicknesses and high densities and strengths and one thick layer between both plates with low strength and density known as core that is composed of concrete. Cohesive material-epoxy resin or shear connectors are usually used to connect the plates to the concrete core. SCS sandwich composites are being develope...
