Chuchmai A. The development of analytical and numerical methods for the calculation of reinforced concrete caisson ceilings

The object of research - the process of deformation of structures caisson type; goal - development of analytical, numerical and experimental methods of investigation of the stress-strain state of reinforced concrete coffered ceilings; methods - linear algebra, numerical and analytical methods of structural mechanics, computer modeling, methods of experimental investigations; results - developed methodology for integrated studies of the stress-strain state coffered ceilings based on the joint use of analytical, numerical and experimental methods; spatial analysis model of the system of cross-beams and the method of its calculation; an engineering method of determining the torsional stiffness of beams with normal cracks; analytical dependences of numerical-analytical boundary element method applied to structural analysis of caisson type; developed practical methods of modeling and calculation coffered ceilings with software SCAD and ANSYS; introduced - embedded in design practice.
