After unexplained breakage of glass within an installed glass balcony railing system, CDC was hired to investigate the conditions, and peer review the project drawings and calculations. We concluded that the railing stanchion plates were overstressed. CDC modeled the condition in ANSYS, analyzing stress and deformation of the materials under design loading - demonstrating that the design was not adequate to resist loads applied. CDC designed a new, structurally adequate stanchion plate within the thickness and width constraints of the existing conditions.
