Flexural Strength of Exterior Metal Building Wall Assemblies with Rigid Insulation
MetadataShow full item record
The goal of this research study is to observe and quantify the influence of rigid board insulation on through-fastened girt capacity. Rotational restraint tests are performed to study local rotational stiffness at the flange-insulation contact point. Vacuum box tests on through-fastened wall systems are conducted to explore the effect of insulation thickness on the R-factor. The results will be used to support new code language in AISI S100-07 D6.1 that accommodate capacity prediction of metal building wall systems with rigid board insulation.
