Mechanical Properties of Plasterboards: Experimental Tests and Statistical Analysis

Abstract

Plasterboard components are widely used in current buildings worldwide. Despite their extensive use, the lack of a comprehensive test campaign on plasterboards in the current literature is denoted. An extensive test campaign, consisting of 302 tests, on plasterboards is performed both in tension and compression. A set of five plasterboard typologies is selected. The tests are performed in two different load directions, i.e. parallel or transversal to the direction of production. Tensile strength of boards is systematically smaller than compressive strength, whereas elastic modulus values in compression and in tension are similar. Two different regression laws are defined, matching compression and tension behavior, respectively. An orthotropic behavior is exhibited in case the boards are loaded in tension. The significant influence of board thickness on their mechanical properties is also highlighted. Finally the most appropriate probability distribution function is estimated for several mechanical parameters and the corresponding data dispersion is evaluated. The performed activities can be used as reference for future numerical studies involving plasterboards.

Mechanical and Non-Destructive Testing of Plasterboards Subjected to a Hydration Process

“…Gypsum plasterboards were composed of a plaster core encased in and firmly bonded to outer paper liners. Due to its fabrication method, the lining and also the board as a whole showed significant anisotropic properties [17][18][19][20]. Therefore, the mechanical properties of plasterboard sheets were determined in parallel and perpendicular to the sheet production direction, applying standard EN 520 [21].…”

“…This experiment showed that product merely discarded in the environment could be also recycled. The influence of humidity on the properties of concrete was investigated by using contact and non-contact methods and was reported in [17], but, so far, no similar research in relation to plasterboards was performed.…”

Theoretical and experimental evaluation of timber-framed partitions under lateral drift

“…Gypsum plasterboard has relatively low compressive and tensile strengths which can result in early onset of damage [57,71]. The corners of the gypsum plasterboards crushed, creating wrinkles Table 7: Parameters for the tested specimen.…”

Loadbearing Capacity of LSF Walls Under Fire Exposure

“…The LSF is the only material to be considered for the loadbearing capacity of the wall. All other materials, that may contribute to the strength and collapse mode of the structure (Petrone, Magliulo, & Manfredi, 2016), will not be considered for the calculation of the loadbearing capacity. An incremental and iterative solution method was applied to determine the loadbearing capacity.…”
