Abstract

fetched live from OpenAlex

Structural Insulated Panels (SIPs) gained popularity in construction literature since Nicholls introduced the concept in 1991. SIPs have advantages over conventional methods like light-frame construction due to their stiffness, which governs their general structural behavior. Corrugated panels, as highly rigid materials, could bring stiffness to this system. While corrugated panels are known for their high rigidity, their mechanical application in SIPs has not been well-documented in the literature. This study aims to address this gap by investigating the mechanical performance of innovative corrugated SIP prototypes. Prior to full-scale manufacturing, cohesion tests were conducted to verify laboratory bonding. Two types of tests were carried out to evaluate the mechanical performance of the prototypes. Firstly, compression tests were performed on 2400 mm x 1200 mm samples. The results indicated that the prototypes exhibited greater stiffness than wood light frames, with minimal buckling deformation and brittle fractures. Secondly, shear tests were conducted on 2400 mm x 2440 mm specimens, revealing that they were four to seven times stronger than lightweight timber frames. The prototypes also demonstrated increased stiffness, with minimal displacement and brittle fractures. In comparing existing lightweight structural systems and prototypes it became evident that the prototypes demonstrated greater strength with minimal buckling deformation. However, it was noted that the prototypes exhibited brittleness and would require the addition of ductility through connectors. • Under compressive loads, corrugated panels increase SIPs’ performance. • Prototype's racking performance can be 6 times greater than wood light-frame. • PISOND SIPs require ductile connectors for brittle behavior.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
