In order to study the bearing performance of new prefabricated airport pavement panel (PAPP) structure, a three-dimensional finite element model (3D-FEM) “square PAPP – stratum” was established based on ABAQUS analysis platform, and then mechanical deformation under single wheel various limit load positions carried out. The research showed that influence radius less than side length R panel, ma...

The association between moisture-related microbial growth (mesophilic fungi and bacteria) within insulated exterior walls and microbial concentrations in the indoor air was studied. The studied apartment buildings with precast concrete external walls were situated in a subarctic zone. Actinomycetes in the insulation layer were found to have increased concentrations in the indoor air. The moistu...
