Numerical Evaluation of the Behavior of Steel Frames with Gypsum Board Infill Walls

Abstract

In this paper, the behavior of steel frames with gypsum board infill walls is studied through finite element simulation. For this purpose, a typical steel frame with infill wall which had been previously tested is considered as a benchmark model. The accuracy of a numerical model is verified by calibrating the results of the finite element simulation against those of a corresponding experimental specimen. In the next step, a parametric study is performed on four models in order to study the effects of gypsum board thickness, inclusion of fibers as reinforcement in the infill wall, and local strengthening of the peripheral regions of the infill wall. Each of these factors is related to considerable performance improvement such as strength and ductility of the models. It is observed that adding fibers to the infill wall leads to increase in the strength and ductility of the models up to 3.2 and 6.3 times, respectively. Doubling the thickness of the infill wall results in an increase of 6.7 and 3.3 times in strength and stiffness, respectively; however, this modification causes a significant decrease in the ductility of the infilled frames. Negligible improvement in strength and ductility is achieved through local strengthening of the peripheral regions of the infill walls, whereas it leads to a 30% increase in the stiffness of the models.

A Review Study on Comparison of G+10 Structure with Several Materials Masonry, Concrete and Glass Fiber Reinforced Gypsum Panel (GFRG)

“…The model's stiffness is increased by 30% due to local reinforcement at the borders of the infill walls, but there is very little gain in strength and ductility. [12] Actually, 40% of global energy consumption is attributed to the construction industry. Furthermore, by lowering the interior temperature by 2°C, less energy was used for operating the building's air conditioning system and less energy was needed overall.…”

“…The daily temperature variation on the internal surface of the roof in the air gaped and reinforced regions was decreased by 5.1 and 6.7°C, respectively, with TAGFRG roof cooling. Movahedni, Mehrdad and S. Mohammad Mirhosseini, (2019) [12] in this paper, finite element simulations was used to examine the behavior of steel frames with plasterboard infills. The reference model was a standard steel frame with tested infill walls.…”

“…The infill walls were strengthened in response to damage seen in earlier versions, when stress concentrations caused massive cracks at the infill walls' edges. [12] The GFRG pilot building's internal energy is just 5.24 GJ/m 2 , indicating that, when compared to traditional building technologies, GFRG reduces internal energy by over 50%. This saves electricity and lowers the energy required to cool the building.…”

Macro-Modelling Approach for the In-Plane Cyclic Response of Cold-Formed Steel Partition Walls

“…Using the material test results of GBs [28], σ b is assumed to be 1.48 MPa. Finally, the maximum load-bearing capacity can be obtained from the summation of f gb at expected locations of the corner crushing.…”

Experimental and analytical studies of infill wall with sliding joints considering a door opening

“…29,30 The first approach aims at alleviating the natural fragility of the infill wall with a door opening, employing local strengthening materials like zin-coated steel wire, 31 steel rebars or hoops, 32 perforated steel plates, 33 concrete or wooden lintel, 34 engineered cementitious composites, 35 and textile-reinforced mortar. 28 Additionally, the application of door panels, 36 steel ring frames, 37,38 gypsum board infill walls, 39 and concrete sandwich panels 40 can globally strengthen the resistance of the infill walls. Despite their efficacy in fortifying infill walls around door openings, the potential adverse infill-frame interaction remains a persistent challenge.…”
