Ageenko S. Stress-strain state and stability of the scaffold structures with elements of increased flexibility

Object - the scaffolding frame and modular designs for work on facades of buildings of different heights; methods - the basic tenets of the theory of longitudinal-transverse bending and stability of compressed and compressed-bent elastic rods, methods of resistance of materials, finite element method using a software system SCAD; experimental research methods of building structures; newness - formulated the factors that significantly affect the carrying capacity of design of scaffolding the modular and frame types, the method of calculation of stress-strain state rectilinear elastic rods by deformed the scheme with the taking into account the initial and additional of stress-strain state; the method of calculation of stress-strain state on the deformed scheme constructions and modular scaffolding frame types and their stability taking into account change their calculation schemes in the process of the loading phased due to the exclusion of the initial compliances in the joints of struts with the transition of the hinge in the last rigid; in general defined as the bearing capacity stands at the junction of a rigid scheme provided perpendicular to the axis of the pipe ends in a joint rack and provide full contact ends of the pipe by cross-section interface, solved the problem of calculating the influence of pliability bracing struts for increased flexibility and sustainability of stress-strain state constructions scaffolding modular and frame types, using the finite element method to solve the problem of bearing capacity of in bending the supporting screws scaffolding with the taking into account inclusion of their work in the thread.
