Russian Research

Most of Russian research about composite structure fire resistance are dedicated to the composite slab behavior. The composite beams fire resistance had been never investigated in enough volume: the temperature evaluation within the scope of the actual Russian design codes leads to the significant reduction in the shear connection strength. Meanwhile, there no correlation between the strength decreasing and type of the shear connection. The article provides an overview of the relevant researches and offers some approaches which could take into account bearing capacity reduction of the shear connectors within composite structures design.

Research Situation

Thin wall steel-concrete composite wall panels can be used as bearing member and also as maintenance structural plates, which can satisfy functional requirements of building including bearing capacity, heat insulation and preservation. The problem relating unilateral contact buckling of thin wall steel composite panels has received attention from many construction engineers. The investigation progress is analyzed in general and the investigation questions are illustrated. The research approach and technical routes of delaminated critical load are also presented.
